I‘ve created a Service class in my current company’s utility library for these kinds of problems:
public class Service implements Runnable {
private boolean shouldStop = false;
public synchronized stop() {
shouldStop = true;
notify();
}
private synchronized shouldStop() {
return shouldStop;
}
public void run() {
setUp();
while (!shouldStop()) {
doStuff();
sleep(60 * 1000);
}
}
private synchronized sleep(long delay) {
try {
wait(delay);
} catch (InterruptedException ie1) {
/* ignore. */
}
}
}
Of course this is far from complete but you should get the gist. This will enable you to simply call the stop() method when you want the program to stop and it will exit cleanly.
