在面板上绘图闪一下就没了
Java code

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import java.io.*;

public class FiveChess extends JFrame{
    private JPanel gamePanel = new JPanel();    
    public FiveChess(){
        super();
        this.setTitle("五子棋游戏");
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        this.setBounds(200,20,800,700);
        this.setResizable(false);
        this.getContentPane().setLayout(new BorderLayout());
        this.getContentPane().add(gamePanel, BorderLayout.CENTER);
        
        
        gamePanel.setBackground(new Color(112,122,12));
        
        
        this.setVisible(true);
        
        initGamePanel(gamePanel.getGraphics());
    }
        
    public void initGamePanel(Graphics g){
        g.setColor(Color.red);
        g.fill3DRect(0, 0, 200, 200, true);
        //gamePanel.repaint();
    }
    
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        new FiveChess();
    }

}
