OOPS Concept

OOPS Concept:

Java is an object-oriented programming language, and it follows the fundamental concepts of OOP. Here are some of the key OOP concepts in Java:

1. Classes and Objects: In Java, everything is an object, and classes are the blueprints for creating objects. A class is a template that defines the data and behavior of an object, while an object is an instance of a class.
2. Encapsulation: Encapsulation is the practice of hiding the internal details of an object and providing a public interface for accessing and modifying its state. In Java, encapsulation is achieved using access modifiers such as public, private, and protected.
3. Inheritance: Inheritance is the mechanism by which a new class is created from an existing class by inheriting its properties and behavior. In Java, inheritance is achieved using the “extends” keyword.
4. Polymorphism: Polymorphism is the ability of an object to take on multiple forms or behaviors. In Java, polymorphism is achieved through method overloading and method overriding.
5. Abstraction: Abstraction is the process of simplifying complex systems by modeling them as objects with specific properties and behaviors. In Java, abstraction is achieved using abstract classes and interfaces.

These OOP concepts in Java help in writing efficient and reusable code, improving the overall performance of the application, and reducing code duplication.
