Java OOPS concept

The Object-Oriented Programming (OOP) concepts are fundamental principles that form the basis of object-oriented programming languages such as Java. The OOP concepts include:

1. Encapsulation

    Encapsulation is the technique of hiding the internal details of an object and exposing only the necessary information to the outside world. It allows objects to be treated as a single entity, providing a clear separation between the implementation details and the public interface.


    2. Abstraction

      Abstraction is the technique of representing the essential features of an object, hiding its implementation details. It provides a general view of an object and reduces the complexity of the system.


      3. Inheritance

        Inheritance is a mechanism that allows a new class to inherit the properties and behavior of an existing class. It provides code reuse and enables the creation of a hierarchy of classes.


        4. Polymorphism

        Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as objects of the same class, providing a single interface to the outside world.



        Drawing a circle Drawing a rectangle

        In this example, the main method creates two objects of different classes Circle and Rectangle, both of which extend the Shape class. Both objects are referenced by the same reference variable Shape. The polymorphic behavior is demonstrated by the draw method being executed based on the actual object being referred to, rather than the reference type.
