Description
This Lab was the sum of a lot of topics learned in this course. it was very interesting to see how everything functions and how the change of one word makes a difference. From the lectures I was able to understand what the implications meant when Professor Reyes was explaining yet in the lab, it should me that it wasn’t as simple as the professor made it appear. but this lab really help me to put to practice what the professor said. im starting to enjoy working with Java.

Codes

package lab4;

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

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

package lab4;

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

}
