You Like Java?

Those "cannot resolve symbol," with the symbol being a method method, mean

• • • You misspelled the method name
    • You gave invalid parameters, for example:
      • Too many or too few parameters
      • Wrong type of parameters
    • You did not import the package containing the class cntaining the method
    • The object you are calling the method from does not have the method at all

Hope that helps you, I haven't gone over your code, but I glanced at it, it would be better if you found the erros and fixed them yourself, so you learn. If you have more trouble, post.

Sorry I just took out the errors I got from it and this works.
Perhaps you will find how to add back the features.I never wrote any programs so this is fun for me to play with.I will try harder to get the rest of it back.
