Write a class called MovableCircle that implements the Movable interface given in Lab1 problem. This class contains three int fields x, y, and r, that represents the center and radius of the circle, and one constructor that takes three parameters indicating the initial x and y and radius of the point. Write the constructor and the four methods.

Note: for the MovableCircle, the size() and area() returns the radius and area of the circle,move() method shifts the circle to new position with the specified value of x & y-coordinates given by the user and the printShape prints a string on the console this is a circle at location: xx, yy, where the xx, and yy are the location x and y of the circle.

Extend the given testInterface_HW class to creates a MovablePoint object or a MovableCircle object depending on the users input.

Sample Output:

Enter 1 for movable point and 2 for movable circle. For the Lab assignment, enter only 1.

2

Enter the x coordinate of the circle as an integer

3

Enter the y coordinate of the circle as an integer

4

Enter the radius of the circle as an integer
