Question

I have a program written in Java which uses 3 threads. Everything is working fine in the IDE (Netbeans) and when I kill it it destroys all the threads. When I launch it from the command line and Ctrl-C it the threads keep running. What’s the best way to deal with this ?

Does it kill the main thread as I guess I can use flags after that?

1. You can have some loop control mechanism for your threads using boolean.

2. Else try using Daemon threads, So as there will be No Non-Daemon thread, the JVM will get closed.

By defalut its Non-Daemon, but you can set the thread as Daemon before you call start() method on the thread of execution…

The JVM will terminate ONLY when all the non-daemon threads including the Main thread has terminated.

Eg:

      Thread t = new Thread(MyClass);
      t.setDaemon(true);
