Lots of answers from googling, for example...
In Unix, how can I read a file that ends in .Z, .z, .gz, or .bz2?

Lots of Google topics?
We are looking for a JAVA library/class that will decompress a .Z file.

Welcome to the JavaRanch, repton. You must have missed our naming policy on the way in. In short, we ask that everyone use a first and last name, seperated by a space and not obviously fake as their display name. You can change your name here.
As for your question, you can always use Runtime.exec() to invoke compress/decompress, or you can read up on how Lempel-Ziv compression works and create your own class.

My bad. I missed the java part and wondered why you didn't post in the unix forum. 
The ant task gunzip works for .gz, doesn't seem to work for .Z (although the gunzip unix command I just tried did work on a compressed .Z). FYI, I don't think .z and .Z are the same thing.
