Use the tools in your operating system, say: in Windows you can see this information in the task manager, or in Linux use the top command.

I think he wants to do it programatically.
@JBentley that's possible, yes. I'm just providing a simpler alternative, it might be enough to meet the OP's needs.

I would suggest running jconsole, it will give you these statistics for all currently running Java applications. It can be found in the bin directory of your Java installation.

This should be a comment, not an answer
Sorry... what's the difference? I'm relatively new to SO
An answer contains a solution to the problem. Anything else should be a comment.
Providing a link is not really an answer, it should be posted as a comment in the question. Now if you add some additional information, an explanation, or some code, then that should be posted as an answer. As it is, this answer is risking getting downvoted (not by me, but who knows if someone else decides to do it?)

Use the tool that comes with the java SDK called VisualVM. It can show you much much more than just CPU usage, in real time.
