the main thread and 'other' ones.

[Mike Curwen]

I'm just confirming something with y'all.

If I have something like:

class Foo {
  public static void main (String args[]) {
    
    MyThreadedClass foo = new MyThreadedClass();
  }
}
 
class MyThreadedClass implements Runnable{
 
  Thread _me;
  boolean _loop = true;
 
  public MyThreadedClass() {
    _me = new Thread(this);
    _me.start(); 
  }
  public void run() {
    while (_loop) {
      // do something interesting
      // do something boring
    }
  }
 
}
 

the 'main' thread will conclude very swiftly, but the JVM will not exit (and so my program will still be 'running'), because of the thread started by MyThreadedClass. Or does the 'main' thread hang around until something finally kills the _me thread ?

The main thread will end, but the JVM won't exit until all non-daemon threads have ended.
