Summary

In this chapter, I showed you several ways to temporarily and permanently stop a threads execution. Some of the lessons learned are

		interrupt() can be used to set a threads interrupted status to true and break a thread out of a blocked sleeping or waiting state.

		InterruptedException is thrown to indicate that a thread has noticed that it has been interrupted.

		isInterrupted() can be used at any time on any thread to check whether it has been interrupted, without altering the interrupted status.

		Thread.interrupted() can be used to check whether the current thread has been interrupted, and if so, it automatically resets the interrupted status flag back to false .

		suspend() , resume() , and stop() are deprecated as of JDK 1.2 and should also be avoided in earlier releases.

		Alternative techniques are available to replace the functionality of the deprecated methods .

		Daemon threads automatically stop when all the nondaemon threads have died.
