Indeed the object ThreadMXBean provides the functionality you need (however it might not be implemented on all virtual machines).

In JDK 1.5 there was a demo program doing exactly what you need. It was in the folder demo/management and it was called JTop.java

Unfortnately, it's not there in Java6. Maybe you can find at with google or download JDK5.
