3 Homework 11 Q: I have fixed all the errors in Palindrome.java, but the applet does not work when the Submit button is clicked. A: Check the error message in the command prompt window after the Submit button is clicked. Is there a line number? Check LoginApplet.java to see how variables like id and password are initialized. The variables cannot be used in a comparison statement unless they have values.
