Getting the classes in a package.

Hi all,

Suppose that I want to see what classes are in a package. The
java.lang.Package class does not have any way to get its classes, but the
java.lang.Class class has its getPackage() method.

So I can imagine some convoluted way of getting the classes in a package by
walking through the VM's class path, and inspecting all jar files, etc. Is
there some simpler way?

Dave.

For ClassLoaders that read directories and jar files, that method has
a chance. In general, though, ClassLoaders could choose arbitrarily what
classes they supply, using unpredictable criteria, so there can never be
a foolproof method of finding classes that haven't been loaded.
