You have two assignments to pick from.  JUST DO ONE!  ONLY DO ONE!  YOU CAN ONLY GET POINTS FOR
ONE!

You can only get 7 points.  ONLY DO 7 OF THE THINGS.  DON'T DO ALL 8.


The Stack of Plates
-------------------
You should make a program that shows the numbers a person has pushed in 
order by time.  When the user presses the delete key, the most recent 
number disappears.  When the user presses a number key, the new number 
is added to the top.

* There is an array that holds the numbers.
* When you press the delete key, the most recent number disappears.
* When you enter a number, it appears on top.
* The bottom (first entered) number is at (100,500).
* Works with letters as well as numbers.
* The array can flip when the user wants (might be hard. do last)
* Uses the buttun class to clear the display.
* Turned in by Wednesday of finals week at 4pm.

Hint:  If you want to get an integer from a keypress, you can do this:
   int integerTheyPressed = ke.getKeyChar() - '0';
I will help with this for anyone who wants.








The Head Bopper
---------------
You should make an object named 'Head'.  The program should display five heads.  When
the user clicks on a head, that head should turn into something else (be creative).

* There is both a main class and a helper class.
* The helper class has a paint method.
* The helper class has x and y variables that tell where it is.
* Different heads have different sizes.
* The helper class has a 'clicked(int mouseX, int mouseY)' method that changes
  the icon if the mouse clicks on the icon.
* The program can print the number of icons still in the original (unclicked)
  shape.  (This might be hard.  Do last.)
* Uses the buttun class to reset the display.
* Turned in by Tuesday of finals week at 4pm.
