What is Java OOP's concept

Question

Accepted Answer

Java OOP's concept is a programming paradigm that uses objects to design applications and programs.

Java OOP's concept is based on four main principles: encapsulation, inheritance, polymorphism, and abstraction.
Encapsulation is the process of hiding the implementation details of an object from the outside world.
Inheritance allows a class to inherit properties and methods from another class.
Polymorphism allows objects to take on multiple forms or behaviors.
Abstraction is the process of simplifying complex systems by breaking them down into smaller, more manageable parts.
Example: A car is an object that has properties such as color, make, and model, and methods such as start and stop.
Example: Inheritance can be seen in a class hierarchy where a child class inherits properties and methods from a parent class.
Example: Polymorphism can be seen in a program that uses a single method to perform different actions depending on the object it is called on.
Example: Abstraction can be seen in a program that uses interfaces to define a set of methods that must be implemented by a class.
