Add keyListener to thread

[Qlubbie]

Hello,

I want to try and run a thread that starts running on start and quits after pressing a key.
I cant seem to detect keypresses. can anyone help me out with this?

Thanks in advance..
i cant seem to add code:
Post denied. New posts are limited by number of URLs it may contain and checked if it doesn't contain forbidden words.

its just a code snippit without links or anything...

this is a small part... but how do i add a keyListener in here that listends to a random key?
The class implements KeyListener and the overrided method "keyPressed" sets the isRunning boolean to false... but the keyPressed method is never executed.

public static void main(String[] args) {
		Thread thread = new Thread() {
			public void run() {
 
				while(isRunning){
					System.out.println("running");
					try {
						sleep(1000);
					} catch (InterruptedException e) {
						// TODO Auto-generated catch block
						e.printStackTrace();
					}
			    }
			}
		};
		thread.start();
	}

This is a console program, not a GUI, right?

actually i was hoping to be able to do it with just a thread in the background but i dont think it's possible...
I want a background thread to keep track of key presses and kill the thread after pressing a key like esc or something...

Like a keylogger. but for a different purpose

Listeners, in general, are used with GUI (AWT/Swing) components ..... not for any non-GUI application.

If you want to receive keyboard events "globally" on the system, even if the user is interacting with any other application, beware that this is not possible with the standard Java SE framework.
For these things, you need to know and use some native O.S. functions (if there are, and at least for the Windows platform, the Win32 API contains these functions). And from Java you need to use JNI, Java Native Interface to use these functions. All these are advanced things, that are very specific for each O.S.
