main() method
that started your application. In an applet this will be the thread into which
the applet viewer or web browser was launched.Next, there's a low priority thread that handles garbage collection and runs finalizers.
In programs that use the AWT, there's also a screen updater thread that checks to see if anything needs to be repainted about 100 times a second.
Finally there are any threads your program has explicitly spawned. However
you're program is always running in one thread or another. You're never outside the thread system. You can determine the currently executing thread
with the static Thread.currentThread() method:
public static native Thread currentThread()
public class PrimaryThread {
public static void main(String[] args) {
System.out.println(Thread.currentThread());
}
}
currentThread() method to get a reference to
the current thread so you can manipulate it.
