What are the oop concept of java

OOP concepts in Java are the main ideas behind Java’s Object Oriented Programming. They are abstraction, encapsulation, inheritance, and polymorphism. Grasping them is key to understanding how Java works. Basically, Java OOP concepts let us create working methods and variables, then re-use all or part of them without compromising security.

HOPE THIS HELPED IS NOT SORRY.

OOP stands for Object Oriented Programming. In Java, we create classes to represent different things. For instance:

public class MyClass {

   public static void main(String args[]) {

     Car cr = new Car();

     cr.createCar("Ford", "Green", 2000);

     cr.printInfo();

   }

}

class Car{

   private String model, color;

   private int year;

   void createCar(String md, String cl, int yr){

       model = md;

       color = cl;

       year = yr;

   }

   void printInfo(){

       System.out.println("Car Info:");

       System.out.println("Model: "+model);

       System.out.println("Color: "+color);

       System.out.println("Year: "+year);

   }

}

We create a car object derived from the Car class with whatever properties we want and then we can display the properties of our car with the printInfo() method.

This is just one example of the OOP concept of Java.

you can not change you age soon as you signed up. the only way is too delete your account and use another account to sign up and put your correct age.
