Need help with program.

When I compile and run the following code it prints out 0.0 and null for four of the values.

Hi Devon, welcome to CodeRanch!

As it is now, you'll have a hard time getting your question answered. Your code is unformatted, too long, and we have no idea what it's supposed to do.

Take a look at these links and please try again:
- TellTheDetails
- IsolateTheProblem
- UseCodeTags

The program is supposed to get the information about Courses a student is taking.

I edited your post so it uses code tags correctly. Your code is still too long, you really should try to narrow down the part of the code that's broken. Test your methods individually using println() statements to find out if they are working as expected.
