Sure, I'd be happy to help you create a digital clock using Java GUI! Here's an example code to get you started:
```
import javax.swing.*;
import java.awt.*;
import java.text.SimpleDateFormat;
import java.util.Calendar;
public class DigitalClock extends JFrame {
JLabel timeLabel;
public DigitalClock() {
setTitle("Digital Clock");
setSize(300, 100);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
timeLabel = new JLabel();
timeLabel.setHorizontalAlignment(JLabel.CENTER);
timeLabel.setFont(new Font("Arial", Font.PLAIN, 50));
add(timeLabel, BorderLayout.CENTER);
Timer timer = new Timer(1000, e -> updateTime());
timer.start();
}
private void updateTime() {
Calendar calendar = Calendar.getInstance();
SimpleDateFormat timeFormat = new SimpleDateFormat("HH:mm:ss");
String time = timeFormat.format(calendar.getTime());
timeLabel.setText(time);
}
public static void main(String[] args) {
DigitalClock clock = new DigitalClock();
clock.setVisible(true);
}
}
```
In this code, we create a `JFrame` window with a `JLabel` to display the time. We use a `Timer` to update the time every second, and a `SimpleDateFormat` to format the time as a string.
I hope this helps you get started with creating your own digital clock using Java GUI! Let me know if you have any further questions.
