Stopping a Thread</h3>
The proper way to stop a running thread is to set a variable that the
thread checks occasionally. When the thread detects that the variable
is set, it should return from the <code>run()</code> method.
<P> Note: <code>Thread.suspend()</code> and <code>Thread.stop()</code> provide
asynchronous methods of stopping a thread. However, these methods have
been deprecated because they are very unsafe. Using them often results
in deadlocks and incorrect resource cleanup.
<pre>
// Create and start the thread
<font color="#0066ff"><i>MyThread</i></font> thread = new <font color="#0066ff"><i>MyThread</i></font>();
thread.start();
// Do work...
// Stop the thread
thread.allDone = true;
class <font color="#0066ff"><i>MyThread</i></font> extends Thread {
boolean allDone = false;
// This method is called when the thread runs
public void run() {
while (true) {
// Do work...
if (allDone) {
return;
}
// Do work...
}
}
}
</pre>
