In general, it is better to use a Runnable rather than extending Thread.
You cannot start a Thread instance more than once. You can create
several Thread instances using the same Runnable, and start each Thread
once.

You may find you need a separate Runnable for each Thread, so that
they do not share fields, when you code the actual work, rather than a
simple print-out.
