(1) If I use the NetBeans IDE (6.8 version) and create a deployed version of a fairly large project will it be exactly the same as using the standard "javac" compiler deployed application on the command line.

Will the files produced by both tools be exactly the same. Can you, please, tell me the differences that will occur.

(2) Can you also give me a comparision of the Eclipse files produced on deployment versus the "javac" files produced. Will the two deployed projects be exactly the same.

NetBeans use the same Java compiler as you do command line, so the
generated byte code will be the same assuming you use the same
compiler options (and note that it is quite common to build
with some options for development and with other options for
real build).

If you package in jar files there will always be differences
in files as jar files contain timestamps.

Eclipse comes with its own Java compiler and it could
generate different code.

Best practice is to develop the code in the IDE and
create official build with tools like ant/maven based
on VCS. So it is not something there is much focus on.
