Lab Description

Base on the Movable interface given to use we are to create three classes: Car(), Plane(), and Ship() that implement the movable interface:
moveForward();

          moveBackward();

          stop();

          moveLeft();

          moveRight();

After that we will create a program that will process an array for Movable interface by calling each of the interface method, after creating an object for each of the classes the output should display:

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

———————
