identify the ending of a thread

java.lang.Threads
A thread is finished, when the run()-method was left.

// start a thread:
Thread thread = new MyThread();
thread.start();
 
// call up, if the thread is still running:
if (thread.isAlive()) {
   // thread is still running...
} else {
   // thread is finished
}
 
// wait a stated time for the ending of a thread:
long waitMillis = 10000; // 10 seconds
try {
   thread.join(waitMillis);
   if (thread.isAlive()) {
      // The 10 seconds are over sind um; the thread is still running
   } else {
      // Thread is finished
   }
} catch (InterruptedException e) {
   // The thread was stopped
}
 
// Wait until the thread is finished: finish
try {
   thread.join();
   // This Code will be worn out when the thread is ready.
} catch (InterruptedException e) {
   // Thread was stopped
}
