可不可以用代码实现一下上面的需求呢

当然，以下是一个简单的Java代码实现：

import javax.swing.*;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import java.util.Calendar;
import java.util.GregorianCalendar;
import java.util.TimeZone;

public class DigitalClock {
    private JFrame frame;
    private JLabel hour1, hour2, minute1, minute2, second1, second2;
    private BufferedImage[] digits;
    private Timer timer;

    public DigitalClock() {
        frame = new JFrame("Digital Clock");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(400, 200);
        frame.setResizable(false);
        frame.setLayout(null);

        // Load digit images
        digits = new BufferedImage[10];
        for (int i = 0; i < 10; i++) {
            digits[i] = loadImage("digits/" + i + ".png");
        }

        // Create hour labels
        hour1 = new JLabel();
        hour1.setBounds(10, 50, 50, 100);
        frame.add(hour1);

        hour2 = new JLabel();
        hour2.setBounds(60, 50, 50, 100);
        frame.add(hour2);

        // Create minute labels
        minute1 = new JLabel();
        minute1.setBounds(120, 50, 50, 100);
        frame.add(minute1);

        minute2 = new JLabel();
        minute2.setBounds(170, 50, 50, 100);
        frame.add(minute2);

        // Create second labels
        second1 = new JLabel();
        second1.setBounds(230, 50, 50, 100);
        frame.add(second1);

        second2 = new JLabel();
        second2.setBounds(280, 50, 50, 100);
        frame.add(second2);

        // Start timer
        timer = new Timer(1000, e -> updateClock());
        timer.start();

        frame.setVisible(true);
    }

    private void updateClock() {
        // Get current time
        Calendar calendar = new GregorianCalendar();
        TimeZone timeZone = TimeZone.getDefault();
        calendar.setTimeZone(timeZone);
        int hour = calendar.get(Calendar.HOUR_OF_DAY);
        int minute = calendar.get(Calendar.MINUTE);
        int second = calendar.get(Calendar.SECOND);

        // Update hour labels
        int hour1Value = hour / 10;
        int hour2Value = hour % 10;
        hour1.setIcon(new ImageIcon(digits[hour1Value]));
        hour2.setIcon(new ImageIcon(digits[hour2Value]));

        // Update minute labels
        int minute1Value = minute / 10;
        int minute2Value = minute % 10;
        minute1.setIcon(new ImageIcon(digits[minute1Value]));
        minute2.setIcon(new ImageIcon(digits[minute2Value]));

        // Update second labels
        int second1Value = second / 10;
        int second2Value = second % 10;
        second1.setIcon(new ImageIcon(digits[second1Value]));
        second2.setIcon(new ImageIcon(digits[second2Value]));
    }

    private BufferedImage loadImage(String filePath) {
        BufferedImage image = null;
        try {
            image = ImageIO.read(new File(filePath));
        } catch (IOException e) {
            e.printStackTrace();
        }
        return image;
    }

    public static void main(String[] args) {
        new DigitalClock();
    }
}

在代码中，我们先加载0-9的数字图片素材，然后创建JFrame窗口和JLabel标签来显示数字时钟。定时器每秒更新一次时钟的显示，通过获取当前时间和将时间转换成字符串格式来更新数字图片的显示。注意在updateClock()方法中，我们需要将时区设置为默认时区，以便正确地获取当前时间。同时，我们还需要实现一个loadImage()方法来加载图片文件。在main()方法中，我们创建一个DigitalClock实例来启动时钟应用程序。
