    Default Connect Four GUI Help needed

    Hi, my name is Hobbs and I'm obviously new to these forums. Im a beginner Java student who right now is in a bit of trouble. For my final project I am suppose to make a connect four game complete with GUI. Unfortunately we were not taught GUI in the class and the only chapter in the book tells us how to make a window with buttons. I think the rest of my code is good but I have no idea how to make the game board to show pieces and have it work with my array and such. Any help is appreciated.

    You'll want to post your pertinent code here in the forum for all to see as many will not click on links. If you do post this, please be sure to use [code] [/code] tags per the forum FAQ.

    The tutorials are a good place to start for learning how to write GUI:
    Trail: Creating a GUI With JFC/Swing (The Java™ Tutorials)
    If you don't understand my answer, don't ignore it, ask a question.
