Abstraction in OOPs
Abstraction is the process of hiding the internal details of an application from the outer world. Abstraction is used to describe things in simple terms. It’s used to create a boundary between the application and the client programs.
Abstraction is similar to data encapsulation and very important in OOP. It shows only the necessary information and hides the other irrelevant information. Abstraction is implemented using Abstraction classes and interfaces . The problems in Abstraction are solved at design or interface level.
Objects are the building blocks of Object-Oriented Programming. An object contains some properties and methods. We can hide them from the outer world through access modifiers. We can provide access only for required functions and properties to the other programs. This is the general procedure to implement abstraction in OOPS.
Abstraction can be found in practically all real-world machines.
Your automobile is an excellent illustration of abstraction. Turning the key or pressing the start button is how you start a car. You don't need to know how your car's engine starts or what components it contains. The user is completely unaware of the car's internal implementation and complicated logic.
We can heat our food in Microwave. We press some buttons to set the timer and type of food. Finally, we get a hot and delicious meal. The microwave internal details are hidden from us. We have been given access to the functionality in a very simple manner.
Types of Abstraction
There are two types of abstraction.
Data Abstraction
Process Abstraction
Data abstraction
When the object data is not visible to the outer world, it creates data abstraction. If needed, access to the Objects’ data is provided through some methods.
Data abstraction is a technique for creating complicated data types and exposing only the actions that are necessary to interact with the data type, while keeping the implementation details hidden from outside activities.
The benefit of this approach involves capability of improving the implementation over time e.g. solving performance issues is any. The idea is that such changes are not supposed to have any impact on client code since they involve no difference in the abstract behavior.
Process Abstraction
We don't have to offer information about all of an object's functions. Process abstraction is achieved by hiding the internal implementation of the many functions involved in a user operation.
A piece of software is essentially a set of statements written in any programming language. The majority of the time, statements are similar and are repeated in several locations.
The process of finding all such assertions and exposing them as a unit of work is known as process abstraction. When we build a function to execute any task, we usually use this feature.
Abstraction Implementation in Java
Java provides a non-access modifier “abstract” for implementing abstraction. This abstract modifier can be used with classes and methods but not variables.
The interface provides complete abstraction i.e. it only provides method prototypes and not their implementation. An abstract class provides partial abstraction wherein at least one method should not be implemented.
//abstract class abstract class Car{ abstract void accelerate(); } //concrete class class Suzuki extends Car{ void accelerate(){ System.out.println("Suzuki::accelerate"); } } class Main{ public static void main(String args[]){ Car obj = new Suzuki(); //Car object =>contents of Suzuki obj.accelerate(); //call the method } }
The simple abstraction example that is given above has a class Car. In this class Car, we have an abstract method to accelerate (). Then we inherit this class in the Suzuki class. Inside the Suzuki class, we implement the accelerate method.
The above example simply shows the way in which an abstract class is defined, inherited, and then used in the program.
Advantages of Abstraction
It reduces the complexity of viewing the things.
Helps to increase security of an application or program as only important details are provided to the user.
Avoids code duplication and increases reusability.
Can change internal implementation of class independently without affecting the user.
Conclusion
The principle of data abstraction, allows developers to provide only important data. Averting access to the background details of the data. It is used in the approach that relies on the isolation of the code’s implementation and interface.
With this article at Logicmojo, you must have the complete idea of Abstraction in OOPs.
Frequently Asked Questions (FAQs)
A key concept in object-oriented programming (OOP) is abstraction. It involves hiding an object's implementation details and only showing the user the information that is absolutely necessary. This makes it simpler to read and maintain the code.
Consider the class "Car," for instance. The "Car" class may include attributes like "make," "model," "year," and "color." Additionally, it might have methods like "drive," "startEngine," and "stopEngine."
The internal workings of the 'Car' class are not necessary for the user to understand. They simply need to be aware of the crucial information, such as the disclosed properties and methods. This makes it simpler to read and maintain the code.
The use of abstraction in OOP has numerous advantages. Among the advantages are:
• Improved readability and maintainability of code: Because abstraction hides implementation details, it makes code simpler to read and comprehend. Making modifications to the code and locating and fixing faults may be made simpler as a result.
• Reduced complexity of code: By combining related functions, abstraction can help to make code less difficult. The code may become simpler to comprehend and maintain as a result.
• Improved code reuse : By offering a standard interface for many implementations, abstraction can facilitate code reuse. When creating new code, this can save time and effort.
• Increased code flexibility: By allowing many implementations to be used for the same interface, abstraction can increase code flexibility. As a result, the code may be more changeable.
In OOP, abstraction can be accomplished in a variety of methods. Among the most popular methods are:
• Abstract classes include: Classes that can't be instantiated are called abstract classes. They serve as a standard base class for other classes.
Interfaces are agreements that specify the methods that a class must implement. They are employed to guarantee that the functionality of classes that implement the interface is the same.
• Abstract techniques: Methods that are declared but not specified are called abstract methods. The classes that derive from the abstract class must implement them.
• Abstract characteristics: Declared but undefined attributes are known as abstract properties. The classes that derive from the abstract class must implement them.
OOP code can be made more readable, maintainable, and flexible by using abstraction, a potent tool. It is a core idea in OOP and is applied in numerous contexts.
Abstraction is a key concept in Object-Oriented Programming (OOP) that includes hiding extraneous information and reflecting only the essential characteristics of an object or system. This method has a number of advantages that improve the overall efficacy and efficiency of software development. The advantages of abstraction in OOP are detailed below:
1. Better readability and maintainability of code: By obscuring complicated implementation details, abstraction helps to make code simpler. The code becomes simpler to comprehend and work with by exposing only the fundamental properties and behaviors of an object or system. By making the code more readable, it becomes easier to maintain over time. Instead of getting bogged down in the intricate implementation details, developers may concentrate on the higher-level design and functionality.
2. Less difficult code thanks to abstraction: Instead of having to deal with low-level implementation details, abstraction enables developers to work with higher-level concepts and entities. As a result, the codebase is less complex and easier to manage. Developers may concentrate on the essential functionality and design by abstracting away superfluous complexity, which results in cleaner, more manageable code. The total development process is enhanced and the likelihood of mistakes and faults is decreased thanks to this simplification.
3. Better code reuse: Abstraction encourages the development of classes or components that can be used repeatedly. Developers can lay the groundwork for the construction of various objects or systems by establishing abstract classes or interfaces that offer a common set of behaviors. Multiple classes can extend or implement these abstract entities, allowing for code reuse and fostering a modular and scalable architecture. This not only speeds up development but also ensures consistency and lessens codebase redundancy.
4. More adaptable code: The design and implementation of code are made more adaptable through abstraction. Changes to the underlying code can be done without having an impact on the higher-level code that depends on it by abstracting away particular implementation details. By encouraging loose coupling between components, the codebase is made more flexible and changeable in the future. Additionally, it makes maintenance and updates simpler because changes can be made locally on the appropriate abstract entities without affecting the entire codebase.
There are two primary categories of abstraction in object-oriented programming (OOP):
1. Data Abstraction: Data abstraction aims to conceal the complexity and underlying intricacies of data structures. It enables you to declare an object's fundamental traits and behaviors while keeping the implementation specifics hidden. Data abstraction's major objective is to present a condensed and high-level view of an object so that the user may interact with it without having to worry about how the data is handled or kept within. Classes are commonly used to do this, keeping internal data members private and only exposing relevant operations or methods to the outside world through public interfaces.
2. Method Abstraction: In a class, method abstraction entails hiding the specifics of how a method or function is implemented. It enables you to specify an object's behavior or functionality without disclosing its inner workings. The implementation of concrete methods in derived classes can be modeled using interfaces or abstract classes, which are used to achieve method abstraction. You can create a contract that describes the methods that must be implemented by the derived classes without prescribing the exact implementation details by creating abstract methods or interfaces. This enables polymorphism, in which various objects can be interchangeably treated based on their same interface.
In order to achieve encapsulation and modularity in object-oriented programming, promote code reuse, and facilitate maintainability and flexibility in software development, both data abstraction and method abstraction play critical roles.
Data abstraction, an important concept in object-oriented programming (OOP), entails hiding the internal implementation details of data and simply providing the user with the necessary features or interface. Users can interact with the data without having to comprehend the intricate details of how it is handled or stored. Data abstraction's major objective is to present a high-level, simplified picture of the data so that it is simpler to use and manipulate while still guaranteeing data security and integrity.
Let's use an illustration to clarify data abstraction:
Think about the "BankAccount" class, which represents a bank account. Account number, account holder name, balance, and transaction history are just a few examples of the attributes that can be found in the BankAccount class' internal data. We can hide the internal details of these properties by using data abstraction, while still providing the necessary methods or interfaces for interacting with the account, such as ways to deposit money, withdraw money, and check the balance.
The advantages of data abstraction:
1. Simplicity: Data abstraction offers a high-level view that makes using complicated data structures simpler. Users need just be aware of the fundamental procedures and operations; they don't need to worry about the specifics of implementation.
2. Modularity: Data abstraction encourages modularity in programs by obscuring underlying information. As long as the core interface does not change, a class's or data structure's internal implementation changes have no impact on the code that utilizes them.
3. Security: By limiting access to internal data, data abstraction improves security. You can prevent unwanted modifications and access to sensitive data by only exposing the methods and attributes that are absolutely necessary.
4. Code Reusability: Code reuse is made possible by data abstraction. Once a well-defined abstraction has been built, it may be quickly used to a variety of situations, encouraging the efficient and modular development of code.
5. Maintenance and Debugging: Code maintenance and debugging are made simpler by data abstraction. Finding and fixing problems is considerably easier since adjustments or modifications can be made to the internal implementation without affecting the exterior usage.
In object-oriented programming (OOP), a term called Method abstraction refers to hiding the internal implementation details of a method or function and only exposing the user to the information that is absolutely necessary. It enables people to apply the approach without having to comprehend its subtleties or underlying logic. Method abstraction's major objective is to present a high-level, simplified representation of the method to make it simpler to use and comprehend.
Let's look at a sample of Method abstraction.
Think about the "Calculator" class, which does fundamental arithmetic operations. 'Add()', 'Subtract()', 'Multiply()', and 'Divide()' are examples of methods that may be included in the Calculator class' internal implementation. We can hide the specific techniques or formulas utilized in these methods and create a straightforward and understandable interface for carrying out arithmetic operations by using method abstraction.Method abstraction advantages:
1. Simplified Usage: By offering a clear and simple interface, method abstraction makes it easier to use complex functions. Without needing to comprehend the underlying methods, users can interact with the method using a small number of parameters and get the required output.
2. Encapsulation: By obscuring the implementation specifics, method abstraction encourages encapsulation. As long as the fundamental interface stays constant, you can change or improve a method's internal logic without having an impact on the code that utilizes it.
3. Code Reusability: Code reusability is made possible by method abstraction. A method abstraction can be used in several contexts without modification once it has been defined. This encourages the efficient and modular creation of code.
4. Polymorphism: Polymorphism, which enables the interchangeability of objects of various classes based on a common interface, is made possible by method abstraction. This offers design and implementation flexibility and extension for complicated systems.
5. Maintenance and Debugging: Code maintenance and debugging are made simpler by method abstraction. The method implementation can be changed internally or fixed without having an impact on outward usage. Finding and fixing problems is much easier as a result.
Data Abstraction in object-oriented programming (OOP) offers several advantages that contribute to the overall quality, readability, maintainability, and flexibility of code. Here are the key advantages of Data Abstraction:
1. Increased readability and maintainability of code: By obscuring complicated implementation details, abstraction helps to make code simpler.

By encouraging loose coupling between components, the codebase is made more flexible and changeable in the future. Additionally, it makes maintenance and updates simpler because changes can be made locally on the appropriate abstract entities without affecting the entire codebase.
Although Data Abstraction in object-oriented programming (OOP) has many advantages, it also has certain drawbacks. The following are the main drawbacks of data abstraction:
1. Reduced code performance: data The user and the underlying data or actions may be separated by an abstraction layer. This extra layer might result in a slight performance hit, especially when direct access to the data would be more effective. The abstraction may result in more method calls, object creation, or indirection, all of which could reduce the overall performance of the code. This expense may become a problem in applications where performance is crucial, thus it is important to carefully weigh the advantages of abstraction against any potential performance effects.
2. More difficult to debug: When utilizing Data Abstraction, the user is not made aware of the internal implementation details of the data and activities. Even though it offers simplicity and encapsulation, this can make debugging more difficult. Developers may need to go into the underlying abstraction when they run into problems or unexpected behavior in order to identify the root of the issue. This can make debugging more difficult and time-consuming as it necessitates following the code's flow via various abstraction levels.
3. Increasing testing difficulty: When compared to code that has direct access to implementation details, testing code that largely relies on data abstraction might be more challenging. It can be more difficult to isolate and test individual code units when dependencies and interactions between several components are introduced by abstraction. Within the abstraction layer, test cases can need to take into account a variety of scenarios and interaction combinations, thus adding complexity and effort to the testing process. To verify correctness, the abstraction layer itself might also need to be tested separately, which would add another level of testing complexity.
It's crucial to remember that these drawbacks are factors to take into account when using abstraction in code design rather than intrinsic limits of Data Abstraction. It is feasible to minimize these drawbacks and increase the advantages of data abstraction with proper preparation and thought. Selective optimizations can be used for performance-critical parts, and profiling tools can help locate potential bottlenecks. Effective logging, debugging tools, and an understanding of the abstraction layer can all help with debugging issues. Thorough test planning, including unit tests and integration tests that address the interactions within the abstraction layer, helps improve testing.

Thorough test planning, including unit tests and integration tests that address the interactions within the abstraction layer, helps improve testing.
There are various approaches to achieve abstraction in object-oriented programming (OOP), each providing a particular function. The typical techniques used in OOP to achieve abstraction are:
1. Abstract classes: A class that cannot be instantiated and is used as a template for derived classes is referred to as an abstract class. It has one or more declared but unimplemented abstract methods that are not part of the abstract class. Additionally, concrete methods with predefined behavior can be found in abstract classes. While leaving the precise implementation details to the derived classes, the abstract class describes the common traits and behaviors shared by its derived classes. A means to create a common interface for a group of related classes is provided by abstract classes.
2. Interfaces: A class must implement a contract or a set of behaviors that are defined by an interface, which is a collection of abstract methods. It does not include any implementation information; it merely defines the method signatures. All of the methods defined in an interface's implementation must be provided by the classes that use it. OOP's multiple inheritance is made possible by interfaces since classes can implement numerous interfaces. They give us a technique to establish polymorphism, which allows us to treat many classes interchangeably due to their same interface.
3. Abstract methods: A method that is declared within an abstract class or interface but does not have any implementation is referred to as an abstract method. It merely defines the method signature and is intended to be overridden or implemented in classes that implement the interface rather than in classes that derive from it. A way to impose a specific behavior or functionality in derived classes or classes that implement an interface is using abstract methods. They act as placeholders, which means the derived or implementing classes must implement them.
4. Abstract properties: Similar to abstract methods, abstract properties declare a property without offering any implementation, as opposed to defining a method signature. In order to guarantee the presence of specified attributes in the derived classes or implementing classes, abstract properties are often employed in abstract classes or interfaces. The implementation information for the abstract properties must be provided by the derived or implementing classes.
These various techniques for accomplishing abstraction offer flexibility and permit OOP's code reuse, modularity, and polymorphism. Since the derived classes or implementing classes offer the exact implementation details, they permit the separation of concerns because the abstract classes or interfaces specify the fundamental properties and behaviors. The exact requirements and design objectives of the program will determine whether to use abstract classes, interfaces, abstract methods, or abstract attributes.
In object-oriented programming, an abstract class is a class that cannot be instantiated or used directly to produce objects. It acts as a guide or model for the development of derived classes, which can derive from the abstract class and offer particular implementations for its abstract methods or replace its non-abstract methods.
A common base class that represents the shared traits, actions, or characteristics of a group of related classes is often defined using abstract classes. They offer a means of defining a standard interface or contract that the derived classes must follow. The properties, abstract methods, and concrete methods can all be found in an abstract class.
Important characteristics of an abstract class include:
1. Inability to instantiate: Abstraction prohibits direct instantiation of abstract classes. It implies that you are unable to produce instances of the abstract class itself. To implement the abstract methods and give specific implementations, you can make objects of its derived classes.
2. Abstract methods: One or more abstract methods may be defined by an abstract class. In the abstract class, these methods are specified but without any implementation. They act as placeholders, which the derived classes must implement. All the abstract methods inherited from the abstract class must have an implementation in each of the derived classes.
3. Concrete methods: Aside from abstract methods, an abstract class may also include concrete methods with established implementations. Both the abstract class and its descendant classes are able to utilise these concrete methods. The derived classes can use the shared functionality provided by concrete methods.
4. Inheritance: Derived classes extend the functionality of the abstract class and offer particular implementations for its abstract methods by inheriting from it. To be accepted, the derived classes must implement each and every abstract method specified in the abstract class.
In object-oriented programming, abstract classes are essential for achieving abstraction, mod
ularity, and code reuse. They offer a method for creating a common behavior or interface for a collection of related classes while enabling each derived class to have its own unique implementation. The base of class hierarchies are abstract classes, which support polymorphism and encourage effective code organization.In object-oriented programming, an abstract method is a method that is declared in an abstract class or interface but does not include any implementation information. It acts as a stand-in or contract, specifying a method signature without supplying the method's real source code. The classes that derive from the abstract class or implement the interface are in charge of implementing the abstract method.
The essential properties of an abstract approach are as follows:
1. Declaration without implementation: An abstract method is declared by stating its signature, which includes the method name, parameters, and return type, in the abstract class or interface. It does not, however, include any actual code or implementation information. Instead of a method body, a semicolon (;) marks the conclusion of the method.
2. Absence of a method body: Unlike normal methods, abstract methods lack a body or a group of words that specify their function. The derived classes or classes that implement the interface are where they will be overridden or implemented. The abstract method serves as a contract, requiring that the abstract method's implementation be provided by any class that derives from the abstract class or implements the interface.
3. Implementation in derived classes or implementing classes: The derived classes that derive from the abstract class or the classes that implement the interface are in charge of implementing the abstract method. The abstract method's concrete implementation must be provided by each deriving or implementing class, while conforming to the abstract class or interface's declared method signature. The derived class or implementing class fulfills the contract set out by the abstract method by offering the implementation.
In order to achieve polymorphism and enforce particular functionality or behavior in derived classes or implementing classes, abstract methods are crucial. They enable the abstract class or interface to specify a standard method signature that all deriving or implementing classes must have. Since abstract methods are flexible and extensible, different classes can offer their own distinctive implementations while still adhering to a standardized method signature.
It's crucial to remember that a class must be explicitly designated as abstract if it has one or more abstract methods. Although an abstract class cannot be directly instantiated, it can operate as a base class for derived classes that offer concrete implementations of its abstract methods.
An abstract method is, in essence, a method that is specified but not implemented in an abstract class or interface. It acts as a contract by defining a method signature that the derived classes or implementing classes must adhere to. Polymorphism is made possible through abstract methods, which also guarantee behavior uniformity between classes.
In object-oriented programming, an abstract property, commonly referred to as a virtual property, is a property that is specified in an abstract class or interface but does not have an accompanying implementation. It establishes a contract or demand that the derived classes offer a particular property with a predetermined behavior or data type.
The essential traits of an abstract property are as follows:
1. Declaration without implementation: An abstract property is declared by providing its name and data type in the abstract class or interface. It lacks a getter or setter method that specifies how the property is accessed or changed, unlike ordinary properties. It acts as a placeholder instead, stating that any class that implements the interface or derives from the abstract class must supply an implementation for the abstract property.
2. Absence of implementation information: An abstract property lacks a corresponding implementation or method for storing its value. It stands for a prerequisite or expectation that derived classes have to meet. The derived classes are responsible for the implementation details, such as how the property is computed or saved.
3. Implementation in derived classes: The derived classes that derive from the abstract class or the classes that implement the interface are in charge of implementing the abstract attribute. The concrete implementation of the abstract property must be provided by each deriving or implementing class. The getter and setter methods for changing and accessing the property are also defined here.
When you wish to ensure a consistent interface across derived classes or implementing classes, abstract properties come in handy. Any derived or implementing class must offer a property with a specific name and data type, according to the requirements set forth by the abstract class or interface by declaring an abstract property. Since multiple classes can be used interchangeably based on their shared interface, which contains the abstract trait, this enables polymorphism.
It's crucial to remember that a class that contains one or more abstract attributes must also be defined as such. A base class for derived classes that give concrete implementations for its abstract characteristics, an abstract class cannot be instantiated directly but acts as a base class for such classes.
There are a few recommended practices that can help optimize the advantages of abstraction in object-oriented programming (OOP) and raise the overall caliber of the code.
The main guidelines for employing abstraction are as follows:
1. Use abstraction to hide implementation details: One of abstraction's main goals is to conceal how classes, methods, or data structures are actually implemented internally. You give the consumers of your code a streamlined and high-level view by encapsulating the complexity into abstract classes, interfaces, or abstract functions. This division of duties enhances the organization, security, and maintainability of the code.
2. Use Abstraction to improve readability and maintainability of code: Use abstraction to develop clear, succinct interfaces that concentrate on crucial behaviors and functionalities. Abstraction enables you to design code that is easier to read and maintain. The code is made easier to read and understand by abstracting away pointless details. A further benefit of abstraction is that it encourages modular architecture, which makes it simpler to update and maintain code over time. A well-designed abstraction should be simple to understand and maintain, improving the codebase's overall readability and maintainability.
3. Use abstraction to make code less difficult: By offering high-level interfaces and obscuring sophisticated implementation details, abstraction makes code usage simpler. Abstraction lessens the cognitive load on users and makes the code more manageable by concentrating on the fundamental traits and behaviors. It prevents developers from being overburdened with needless complexity and enables them to think more abstractly. As a result, the code is simpler, less prone to errors, and simpler to understand and maintain.
4. Use abstraction to encourage code reuse: Abstraction encourages code reuse by establishing generic interfaces or abstract classes that can be used by various classes to extend or implement them. You can reduce waste and increase efficiency by encapsulating common behaviors or attributes in abstract classes or interfaces. Instead of starting from scratch every time, reuse existing abstractions to speed up development, assure consistency throughout the codebase, and prevent inconsistencies.
5. Use abstraction to make code more adaptable and flexible: Abstraction makes code more adaptable and flexible. You can improve or modify the internal details without impacting the external code that depends on them by separating the abstraction from its implementation. This adaptability makes it simpler to include new features, technological advancements, or requirement adjustments. A stable contract or interface provided by well-designed abstractions protects users from underlying changes, making the code more durable and adaptable.
