Objective:
The goal for this lab is to create 3 classes which they are called Car(), Planes(), Ships() and for each class we are suppose to implement each class, and then we have to create a class that can process an array of Movable by calling classes.

Code:

package lab6;
public class MovableApp 
{
	public static void main(String[] args) 
	{
		Movable[] myMovables = new Movable[3];
		myMovables[0] = new car();
		myMovables[1] = new planes();
		myMovables[2] = new ships();
				for(Movable m: myMovables){

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

package lab6;
public interface Movable 
{
	public void moveForward();
	public void moveBackward();
	public void stop();
	public void moveLeft();
	public void moveRight();
}

package lab6;
public class car implements Movable
{
	public static void main(String[] args) 
	{
	}
	public void moveForward() 
	{
		System.out.println("Car drives forward");
	}
	public void moveBackward() 
	{
		System.out.println("Car drives backward");
	}
	public void stop() 
	{
		System.out.println("Car parked");
	}
	public void moveLeft() 
	{
		System.out.println("Car turns left");
	}
	public void moveRight() 
	{
		System.out.println("Car turns right");
	}
}

package lab6;
public class planes implements Movable 
{
	public static void main(String[] args) 
	{
	}
	public void moveForward() 
	{
		System.out.println("Planes Fly Foward");
	}
	public void moveBackward() 
	{
		System.out.println("Planes Fly backwards");
	}
	public void stop() 
	{
		System.out.println("Planes parked");
	}
	public void moveLeft() 
	{
		System.out.println("Planes turn left");
	}
	public void moveRight() 
	{
		System.out.println("Planes turn right");
	}
}

package lab6;
public class ships implements Movable 
{
	public static void main(String[] args) 
	{
	}
	public void moveForward() 
	{
		System.out.println("ships navegates Foward");
	}
	public void moveBackward() 
	{
		System.out.println("ships navegates backwards");
	}
	public void stop() 
	{
		System.out.println("ships Stop");
	}
	public void moveLeft() 
	{
		System.out.println("ships turn left");
	}
	public void moveRight() 
	{
		System.out.println("ships turn right");
	}
}
