Palindrome Testing Applet

What is a palindrome? A palindrome is a word or phrase which reads the same forward or backward. Here are some examples: "radar", "Abba", "Madam, I'm Adam"

This little applet let's you type in a phrase and then analyzes it to see if it is a palindrome. Spaces and some punctuation marks are ignored, as are differences in case. Therefore, "A man, a plan, a canal: Panama" is a valid palindrome.

To use the applet, just type a phrase in the 'Input' area, and either hit Return or click on the 'Test for Palindrome' button. The verdict will be displayed in the middle of the applet's display area.
