Explain the OOPS concepts of Java in detail.

Question

Accepted Answer

Java OOP concepts include encapsulation, inheritance, polymorphism, and abstraction, forming the foundation of object-oriented programming.

Encapsulation: Bundling data and methods. Example: A class 'Car' with attributes like 'color' and methods like 'drive()'.
Inheritance: Mechanism to create a new class from an existing class. Example: 'Sedan' class inherits from 'Car' class.
Polymorphism: Ability to take many forms. Example: Method overriding where a subclass provides a specific implementation of a method.
Abstraction: Hiding complex implementation details. Example: Using interfaces like 'Vehicle' to define common behaviors without specifics.
