用BufferedImage实现多线程绘图

import java.awt.Graphics;
import java.awt.image.BufferedImage;
import javax.swing.JFrame;

public class MultiThreadDrawing extends JFrame {
    private BufferedImage image;

    public MultiThreadDrawing() {
        super("Multi-Thread Drawing");
        setSize(400, 400);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        image = new BufferedImage(getWidth(), getHeight(), BufferedImage.TYPE_INT_ARGB);
    }

    public void paint(Graphics g) {
        super.paint(g);
        g.drawImage(image, 0, 0, this);
    }

    public static void main(String[] args) {
        MultiThreadDrawing frame = new MultiThreadDrawing();
        frame.setVisible(true);

        for (int i = 0; i < 10; i++) {
            Thread thread = new Thread(new DrawingThread(frame.image));
            thread.start();
        }
    }

    private static class DrawingThread implements Runnable {
        private BufferedImage image;

        public DrawingThread(BufferedImage image) {
            this.image = image;
        }

        public void run() {
            Graphics g = image.getGraphics();
            // 在此处进行图像绘制操作

            g.dispose();
        }
    }
}
