Extend the Shape application you have already developed to include the following:
a. Add buttons (and associated logic) to Draw, Store and Load shapes. Store and Load should allow the user to specify a file name.
b. Associate a random color with each shape and display it in its outline form (if not already coded)
c. Add the facility to specify how many shapes to draw (this should replace the original command line option).
d. Create a border around the shape drawing region i.e. so no shape touches the edge of the frame

Hints we got-
Action listeners will be needed for the buttons
Review the JFileChooser class.
Consider developing storeDrawing and loadDrawing methods
ObjectOutputStream and ObjectInputStream might be useful classes to explore however classes must implement the serializable interface. When reading an object from a file it will have to be cast to an appropriate type.
Use the repaint method when you want to display a new drawing
Some of the classes you use might throw exceptions and in some cases you may have to catch them in order to compile your program.

Sorry if this is too easy but its just to get me started.

"Extend the Shape application you have already developed"
Are you kidding?`

We didn't develope anything.

Post a question if you have problems and we'll be glad to help, but do not expect us to do your work.
