This lab illustrates the following concepts

• recursion
• swing and events
• MVC

Sun libraries documentation

1) Recursion

Recursion slides

Example 1 (solution):

• Write a recursive method that takes a string and returns true if the string is a palindrome
• Write a recursive method that takes an integer and returns the number of digits in that integer
• Write a recursive method that prints the solution to the Towers of Hanoi puzzle (see the slides given above)

Example 2:

• Sample: Box.java, BoxViewer.java
• Solution: Box.java, BoxViewer.java

2) Swing and events

Sample: Face.java, FaceTest.java

Solution: Face.java, FaceTest.java

3) MVC

Do 2) using an MVC approach (solution: Lab.zip)
