Lab Description:

In this lab we are to use interface to write the following program. Than make 3 program Plane, Car and Ship that implements the program.

CODE:

package lab6;

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

package lab6;

public  class Plane implements Movable {

	@Override
	public void moveForward() {
		System.out.println("Plane flying forward");
	}

	@Override
	public void moveBackward() {
		System.out.println("Plane taxiing backward");
	}

	@Override
	public void stop() {
		System.out.println("Plane landed");
	}

	@Override
	public void moveLeft() {
		System.out.println("Plane flying left");
	}

	@Override
	public void moveRight() {
		System.out.println("Plane flying right");
	}
}

package lab6;

public  class Car implements Movable {

	@Override
	public void moveForward() {
		System.out.println("Car drives forward");
	}

	@Override
	public void moveBackward() {
		System.out.println("Car drives backward");
	}

	@Override
	public void stop() {
		System.out.println("Car parked");
	}

	@Override
	public void moveLeft() {
		System.out.println("Car drives left");
	}

	@Override
	public void moveRight() {
		System.out.println("Car drives right");
	}
}

package lab6;

public  class Ship implements Movable {

	@Override
	public void moveForward() {
		System.out.println("Ship navigates forward");
	}

	@Override
	public void moveBackward() {
		System.out.println("Ship navigates backward");
	}

	@Override
	public void stop() {
		System.out.println("Ship docked");
	}

	@Override
	public void moveLeft() {
		System.out.println("Ship navigates left");
	}

	@Override
	public void moveRight() {
		System.out.println("Ship navigates right");
	}
}

package lab6;

public class MovableStep {
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Movable[] myMovables = new Movable[3];
		myMovables[0] = new Plane();
		myMovables[1] = new Car();
		myMovables[2] = new Ship();

		for (Movable v: myMovables){
			v.moveForward();
			v.moveBackward();
			v.stop();
			v.moveLeft();
			v.moveRight();
			System.out.println("------------------");
		}
	}
}
