Sun has always gave their JDK's away for free. Go to
http://java.sun.com to download.

On the other end, they'll probably need to go to http://www.apple.com
to get an Apple Java Runtime Environment, if they don't already have one
installed.

One note: while the basic syntax of Java is similar to C, Java is
_not_ C. Java is Object-Oriented. It has its own API that has no
similarity to any of the standard C APIs. You shouldn't have too hard
of a time learning the language, but don't think for a second that this
is going to be a simple "cut, paste, and change a few lines of code in
the header" task.

Of course. Java is write-once, run anywhere. There is no problems
with you compiling your Java class files on a PC and running them
anywhere else -- that's the whole point of Java (well, one of the big
ones at least :) ). And file I/O is a pretty basic operation in Java --
the "java.io" package contains everything you'll need to open files and
work with data in structured and unstructured streams.

HTH!

Thanks, I'll give it a bash...

I had heard that Java is actually "Write Once, Debug Many"...we shall see!

Re: Porting C file read/write program to Java

I thought that MS VS C++ had "#ifdef MAC" like stuff that you could
use, the library source code uses it.
