Goals and Background

This lab introduces you to a symbolic debugger to use with Java programs. The debugger is part of the free Eclipse IDE. Eclipse is not installed on aludra, but is available on the campus lab machines. However, you may want to take this opportunity to install Eclipse on your own laptop and bringing it into lab.
Even if you figure out some of the errors in this lab without the debugger, you should go through the practice of using the debugger to get more information about your program; debuggers are useful tools for every programmer, this is a good opportunity to acquaint yourself with one. For some reason students aren't motivated to learn a new piece of software like this when they have a mysterious bug in a program due in 3 hours :-) so we'll give you points for trying it out now!
