Yes that is what hardwired is saying. Whenever you try to run a java class the system looks for a method with the signature

Code:

    public static void main(String[] args)

and that is where your code starts executing. What you need to do is instantiate your clock class and then call the methods as you need them

Code:

    public static void main(String[] args) {
        ClockRx clock = new ClockRx();
        // now you can access fields and call
        // methods in the ClockRx class. for example

       // print details of clock
       System.out.println(clock.);

      // tick the clock
       clock.tick();

       // print details of clock
       System.out.println(clock.);
    }
