Answer 1

The proper way to stop a thread is to interrupt it (stop() is deprecated and may have nasty side effects):

t1.interrupt()

This will cause an InterruptedException to be thrown by methods like Thread.sleep() or Object.wait().

Then just add a catch block for this exception and simply break out of the while loop.

EDIT: I now realised that your infinite loop is running within the main thread, there's no thread created by your code, it's just run()ning a Runnable. You need to call Thread.start() at some point to spawn a new thread.
