Possibly not. If you compile with a different Java version
than they used, the class file format's version number might be
different. If you use different compiler options than they did,
the class files may contain different kinds and amounts of debugging
information. Even if the class files are identical, the archive's
hash code may be different if you used a different ZIP utility.
The "payload" in the class files should be identical (barring
severe version skew), but you'll need something more context-aware
than a full-file checksum.
> Second question: Should i compile this through a linux environment? For example Ubuntu, or can i do the compile from Windows environment too? For example windows 8.1 ?
If the code is entirely in Java, it'll be "the same" (see above)
no matter what environment it's compiled on. If there's any native
(non-Java) code, or if the archive includes things like installers
and such, all bets are off.
