Need some Java help

hi everyone,

i would really appreciate it if some1 could help me out a bit/give me a hint or something for some work i am doing.

Basically i am trying to make a turtle move around a track, which i have done. But the turtle also has to find the track in the first place. Whatever i put into the method body of the findTrack() method nothing happens. The turtle does absolutely nothing.
I am not sure what i am missing, have i missed something in the constructor or something, i am not sure, this has been bugging me for a whole week now.

You can download the code from my personal website so you can have a look at it:

just compile all the classes and then run MAIN, which will launch the turtle. which does nothing because it cant find the track.
I will be really really really gratefull if you can have a look at this for five minutes because my brain is about to explode! i just need a hint or something so i know where to get started.
Thanks,
ThaGeza
