Hi,

I'm working on this program for my CS class. Does anyone have
suggestions on how to do this efficiently?

Thanks

I would suggest an UCS or A* search..
on the tree of possible moves..

you could use distance of blocks to the target in Manhattan metric as a
heuristic to find your goal faster.

What have you got so far?

A good group for those learning Java is
comp.lang.java.help

Well, trying to get someone here to code it for you is
extremely inefficient*, but ..
- putting some study in,
- outlining a course of action, and
- asking for specific advice/critique on that course of action
..might be efficient.

* Because we won't.

Note also that a specific, relevant subject line is more
likely to attract the attention of those that can help with
answers to more specific questions.

This project seems to be a bit beyond true beginner, but the advice
about reading the assignment is very applicable. The description
contains a lot of good advice about how to approach it, and the issues
to consider.
