如何用Java Swing制作一个动画数字计数器？

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class CounterFrame extends JFrame {
    private JLabel counterLabel;

    public CounterFrame() {
        setTitle("动画数字计数器");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(300, 200);
        setLayout(new FlowLayout());

        counterLabel = new JLabel("0");
        counterLabel.setFont(new Font("Arial", Font.BOLD, 48));
        add(counterLabel);

        setVisible(true);
    }
}

public void startCounterAnimation() {
    Timer timer = new Timer(1000, new ActionListener() {
        int count = 0;

        @Override
        public void actionPerformed(ActionEvent e) {
            counterLabel.setText(String.valueOf(count));
            count++;
        }
    });
    timer.start();
}

public static void main(String[] args) {
    CounterFrame counterFrame = new CounterFrame();
    counterFrame.startCounterAnimation();
}
