{
       int speed;
       vehicle1()
       {
              speed=50;
       }
       void stop()
       {
              System.out.println("vehicle stopped");
       }
       void move()
       {
              System.out.println("Every vehicle should move this way only");
       } //overridden method
}//super class

class car1 extends vehicle1
{
       int speed;
       car1()
       {
              speed=80;
       }
       void move()
       {     
              System.out.println("As a car I move in any own way also");
              System.out.println("own speed :"+speed);
              System.out.println("parent given speed :"+super.speed);
       }//overriddingmethod
}//sub class

public class superusage {
      
       public static void main(String[] args) {
              car1 c1= new car1();
              c1.stop();
              c1.move();
       }

Note: non-static nested class is known as “inner class”. In the above example class B is nested but not an inner class. Ex: class D {        static c        {                      } //nested class, but not an inner class , because of static class. } //outer class. ->we have three different kinds of inner classes. 1) Member inner class 2) Meth...
