    Default Re: Simple Homework applet problems

    You need to let folks know what errors are happening and where rather than simply dumping your code in the forum. If your code has many compilation errors you're also going about your coding wrong -- you should not add any new code while a compilation error exists until the error has been fixed.

    Most importantly you'll want to read the Java tutorials to see how a program should be written. This is like math where all knowledge is built incrementally on a solid foundation. Without the foundation we won't be able to help you.

    Edit, this is a double post of an already active post in the forum. Please read the forum rules and don't do this. This thread is being locked. Do not do this again.
