Java Exercise

3. Movable Point
A. Write the classes as shown in the following class diagram. Movable is an interface and MovablePoint implements it. ‘~’ means package access but you can just make it public. (pic1.png)

B. Now add the class MovableCircle which also implements the interface Movable and is composed of a MovablePoint. Add a tester that allows the user to enter the radius and center of a MovableCircle. After that ask the user if they want (yes/no) to move the circle and how they want to move it (up, down, left, right). Everytime the circle is moved, you should output its changed position. If the user says “no” the program ends. (pic2.png)
