Java: Program closes, when it has to listen

Question

So I'm trying to "log" keys that are being pressed. The problem is when I run my code, the program just auto stops and sends me back to where I can code.

I use Eclipse

    import org.jnativehook.keyboard.NativeKeyEvent;
    import org.jnativehook.keyboard.NativeKeyListener;

    public class Listener implements NativeKeyListener {
        public static void main(String[] args) {
            System.out.print("Program started");
        }

        @Override
        public void nativeKeyPressed(NativeKeyEvent arg0) {
            System.out.print("A key was pressed");
        }

        @Override
        public void nativeKeyReleased(NativeKeyEvent arg0) {
            // TODO Auto-generated method stub

        }

        @Override
        public void nativeKeyTyped(NativeKeyEvent arg0) {
            // TODO Auto-generated method stub

        }   
    }

You need to add the listener to the GlobalScreen object and keep the program running.
