D. Debugging

Compile-Time Errors

The compiler is spewing error messages. I’m getting a weird compiler message, and it won’t go away. I can’t get my program to compile no matter what I do. I did what the compiler told me to do, but it still doesn’t work.

Run-Time Errors

My program hangs. When I run the program, I get an exception. I added so many print statements I get inundated with output.

Logic Errors

My program doesn’t work. I’ve got a big, hairy expression and it doesn’t do what I expect. My method doesn’t return what I expect. My print statement isn’t doing anything. I’m really, really stuck and I need help. No, I really need help. I found the bug!
