Help with math program

  #1
Jan 7th, 2009
Hey, I am tutoring this kid in java and he has to use TurtleGraphics and BreezySwing, neither of which I have used in a while. I am having trouble figuring out some of his problems. I will post both his code and how I altered his code. I am wondering about a couple of things, one is he uses the method addLabel(), which I cant get to work and am wondering if that is really a method?

Also, he need a main method and I'm not sure what to put in the main method to make it all run.
Here is his code, below this will be how I altered the code:
Java Syntax (Toggle Plain Text) 
  1. //"Math is our Game" - A math testing program for First through Fourth grade students
  2.  
  3. //Import GUI packages

I figured out the addLabel thing. The main problem I am having now is wth the main method, I dont know what to put in it to make the program run.

How have you tested anything at all in order to alter it if you do not know what should go into main() to make it run?
No one here is going to be able to tell you for certain, since you are extending some "GBFrame" class which is not a standard JDK class, but you probably need to create an instance of Math, set a few properties on it, and set it to be visible.

Fixing up the formatting couldn't hurt as well, since the indentation is all screwed up in what is posted above. That would make it a lot easier for you to follow the logical blocks within the code.

Edit: And rename the classes to something more meaningful than "Math" and "Math2". "Math" certainly doesn't denote any logical relationship to a "GBFrame".

Ok I'll try that. The code isn't mine, if I had written it I would have definitely formatted it better and named stuff better.
