public class sig {
    public static void main(String[] args) throws Exception {
        final Object obj = new Object();
        synchronized (obj) {
            SignalHandler handler = new SignalHandler() {
                public void handle(Signal sig) {
                    System.out.println(sig);
                    System.exit(0);
                }
            };

            for (String sig : args) {
                Signal.handle(new Signal(sig), handler);
            }

            obj.wait();
        }
