Prompt

Design, implement and test a set of Java classes that allows a user to select a shape from a list of available shapes, enter appropriate dimensional parameters and then display that shape in a frame of your Swing-based GUI with the draw method. For 3-D shapes, load an image from a file and display that as a representative. Your list of shapes should be:

Circle

Square

Triangle

Rectangle

Sphere

Cube

Cone

Cylinder

Torus

Take advantage of various Swing AWT components including Layout Managers, Event Handlers, Listener Interfaces, Adapter Classes, Inner Classes, Buttons and other widgets as needed. Take your time on understanding how the graphical components and listeners work so you can easily display appropriate actions based on any event.
