Is there a way to enumurate Java classes with-in a package ?

Question

A programmable way of enumurating java classes with-in a certain packge.

So the result will be a list, something like this:
List l = getClasses("java.lang")
// l == {"String","Thread",...}

Or something similar ?
Is there a way to do this?

thanks in advance!

If you know the package name (like in your example), then look at this:

To get to that point from any given object, get the object's class, and then get the Package object.

Class clazz = myObj.getClass();
Package package = clazz.getPackage();
String packageName = package.getName();
