    And you're still not using code tags. Please do so, it makes the code much easier to read.

    Unfortunately that's not my problem.

    If you did what I have suggested you do without me having to repeat myself and having to keep asking for error messages and the latest code you would be a lot closer to finishing.

    At the bottom of every one of my post in blue writing it shows to use them. You can either type them in or highlight your code and click on the code tags button ('#').

    Re: i need help writing a program using array. ASAP!

    Sorry for triple post. Anyway that is the program, after i fixed error. Just ask if you dont under stand. I think you need to read more books because you need to know how to make a "function"(or called "method" in java) and "declare variable".
