I'm trying to display the current time in a `JFrame`. How can I refresh the text in the `JLabel` without opening a separate frame each time it has to update? 

Here's all of my code so far...

`Test`
------

```
public class Test{

    static String timeDisplay = "";

    public static class time extends Thread{
        static int timeHours = 7;
        static int timeMins = 30;
        static int timeSecs = 0;
        @Override
        public void run(){

            while(true){
                try{

                    time.sleep(1000);
                    timeSecs++;

                    if(timeSecs == 60){
                        timeMins++;
                        timeSecs = 0;
                    }
                    if(timeMins == 60){
                        timeHours++;
                        timeMins = 0;
                    }

                    if(timeHours < 10){
                        if(timeMins < 10){
                            if(timeSecs < 10){
                                timeDisplay = "0" + timeHours + ":" + "0" + timeMins + ":" + "0" + timeSecs;
                            }
                            else{
                                timeDisplay = "0" + timeHours + ":" + "0" + timeMins + ":" + timeSecs;
                            }
                        }
                        else{
                            if(timeSecs < 10){
                                timeDisplay = "0" + timeHours + ":" + timeMins + ":" + "0" + timeSecs;
                            }
                            else{
                                timeDisplay = "0" + timeHours + ":" + timeMins + ":" + timeSecs;
                            }
                        }
                    }
                    else{
                        if(timeMins < 10){
                            if(timeSecs < 10){
                                timeDisplay = timeHours + ":" + "0" + timeMins + ":" + "0" + timeSecs;
                            }
                            else{
                                timeDisplay = timeHours + ":" + "0" + timeMins + ":" + timeSecs;
                            }
                        }
                        else{
                            if(timeSecs < 10){
                                timeDisplay = timeHours + ":" + timeMins + ":" + "0" + timeSecs;
                            }
                            else{
                                timeDisplay = timeHours + ":" + timeMins + ":" + timeSecs;
                            }
                        }
                    }

                    System.out.println(timeDisplay);
                    //CountDown time = new CountDown(timeDisplay);

                }
                catch(Exception e){
                    System.out.println("Something went wrong :(");
                }
            }

        }

    }

    public static void main(String[] args){

        time time = new time();
        time.start();
            try {
                TimeUnit.SECONDS.sleep(1);
                CountDown window = new CountDown(timeDisplay);
                window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                window.setSize(500, 500);
                window.setVisible(true);
            }
            catch (Exception e) {
                e.printStackTrace();
            }

    }

}

```

`CountDown`
-----------

```
public class CountDown extends JFrame{

    private static final long serialVersionUID = 1L;

    static JLabel label = new JLabel();

    public CountDown(String time){

        super("Title");
        setLayout(new FlowLayout());

        add(label);
        label.setText("Current Time: " + time);

        Handler eventHandler = new Handler();

    }

    private class Handler implements ActionListener{

        public void actionPerformed(ActionEvent event){

            String string = "";

            if(event.getSource()==""){
                string = String.format("label 1: %s", event.getActionCommand());
            }

        }

    }

}

```

My intentions for this program was to make a frame that displayed the current time. It's using local time from the program, not the actual time. Thanks in advance, and feel free to let me know if I should change anything in my code to make it better.
