Question

I wrote this code in java and now i have to add a GUI to draw Cube,Square and Circle object on the Drawing Panel. I should add the paint functions of the classes Circle, Cube and Square.I should add position information on the panel, abstract paint function and also update the mSide and mRadius types to int from float according to needs of this new program

Run Scenario is:

Select an object on the toolbar

Click a point on the blue drawing panel

Selected object is drawn on the drawing panel:

Circle center at the clicked point

Square top-left corner at the clicked point

Cube front-top-left corner at the clicked poin

Here is my code, Could you please help me add those GUI and paint functions to my program?
