Determining When a Thread Has Finished
This example demonstrates a few ways to determine whether or not a
thread has returned from its run() method.
// Create and start a thread
Thread thread = new MyThread();
thread.start();
// Check if the thread has finished in a non-blocking way
if (thread.isAlive()) {
// Thread has not finished
} else {
// Finished
}
// Wait for the thread to finish but don't wait longer than a
// specified time
long delayMillis = 5000; // 5 seconds
try {
thread.join(delayMillis);
if (thread.isAlive()) {
// Timeout occurred; thread has not finished
} else {
// Finished
}
} catch (InterruptedException e) {
// Thread was interrupted
}
// Wait indefinitely for the thread to finish
try {
thread.join();
// Finished
} catch (InterruptedException e) {
// Thread was interrupted
}
