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. «interface>> Movable +moveUp():void +moveDown():void +moveleft(): void +moveright():void implements 4 MovablePoint Movablecircle x:int wy:int -xSpeed: int nySpeed:int -radius:int 1 -center: MovablePoint +MovablePoint(x:int,y:int, xSpeed: int,ySpeed:int) +tostring():String +moveUp(): void +moveDown ():void +moveleft ():void +moveRight():void composes MovableCircle(x:int,y:int xSpeed:int, ySpeed:int, radius:int) +tostring():String +moveUp(): void +moveDown ():void +moveleft():void +moveRight(): void
