DESCRIPTION:

In this experiment  an interface named Movable was given, and  I had to create three class CAR(), PLANE() and SHIP(). These classes will implement the interface as well as  I had to create a program that will polymorphically  run an array of the interface by calling each of its methods after creating an object for each one of the classes.

CODE:

public class MovableAction {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub

		Movable[] myMovable = new Movable[3];

		myMovable[0] = new CAR();

		myMovable[1] = new Plane();

		myMovable [2] = new Ship();

			for(Movable m: myMovable){

				m.moveForward();

				m.moveBackward();

				m. stop();

				m.moveRight();

				m.moveLeft();

				System.out.println("-----------------------");

			} 
	}

}
