javac and unjar questions

[Anoop Ranganath <An...@factory23.com>]

I've got two questions.  The first is regarding javac.  Is it possible to
specify attributes so that javac only compiles those source files that have
a newer timestamp than their class files.  (only compile changed files)

And also, it is possible to use unjar to only extract one file?

Thanks,

Anoop

This is exactly how javac works - just make sure your classes are
organized in a directory structure that matches your package structure
and point the task to the root of it. I.e. class a.b.C must live in
${srcdir}/a/b/C.java.

No.
