After downloading and examining your code, which does not appear to be in applet form, and since this is also an introduction, I've moved your thread to the New To Java sub-forum. Instead of posting zip files containing projects, which further contain classes that could possibly contain viruses- it is preferred that you simply enter the code that you have trouble with into your post- using [ code] [ /code] tags.
Note that you also include no specifications for your problem- thus how can we know what it is you need to have us take a look at ? All I see essentially is two source files, Math and TestMath, from that I cannot determine where you need help. You need to be specific. Therefore, please read the
FAQ before you post again.
Thank you for your understanding and cooperation. Once you've done the above, I'm sure someone will be happy to assist.
