Lab Description
This lab experiment will be based on the Movable interface which student will create three classes: Car(), Plane(), and Ship() that implements it. These three classes will implement from Movable with the given interface Movable():

public interface Movable {
public void moveForward();
public void moveBackward();
public void stop();
public void moveLeft();
public void moveRight();
}

We will create a program that will polymorphically process an array of movable which will call each of the interface methods. The object of each one of the classes will be created and implemented so the compiled and processed result should output as following:

Plane flying forward
Plane taxiing backward
Plane landed
Plane flying left
Plane flying right
———————
Car drives forward
Car drives backward
Car parked
Car turns left
Car turns right
———————
Ship navigates forward
Ship navigates backward
Ship docked
Ship navigates left
Ship navigates right
———————

		for (Movable m: myMovable){
			m.moveForward();
			m.moveBackward();
