Count the Monkeys

For this assignment:

1. Make the code runnable.

2. Code your answers on the sheet.

3. This link to JTextFields may prove useful. It explains Integer.parseInt (2b) and it shows how to clear a textField (2a).

4. You must submit your sheet by the end of the period. However, it shouldn't take you that long.

The 8 Pictures you need:

(name as: blank.gif, m1.gif, m2.gif, m3.gif, m4.gif, m5.gif, m6.gif, m7.gif)

The Starter Code: (Cut and paste and hit indent).
