Description:

The main purpose of this lab was to create an interface with three separate classes. The three classes we had to create were car, plane, and ship. The main interface code was provided to us by the professor for the classes. We just had to implement each class using the keyword implements.

Code:

Movable

package lab6;

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

MovableApp

package lab6;

public class MovableApp {

	public static void main(String[] args) {
		Movable[] myMovables = new Movable[3];
		myMovables[0] = new Plane();
		myMovables[1] = new Car();
		myMovables[2] = new Ship();

		for (Movable m: myMovables){

			m.moveForward();
			m.moveBackward();
			m.stop();
			m.moveLeft();
			m.moveRight();
			System.out.println("---------------------");
		}
	}
}

Car

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 turns left");

	}

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

	}
}

Plane

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");

	}
}

Ship

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");

	}
}
