如何在Java中制作瓷砖

import java.awt.*;
import javax.swing.*;

public class TileMaker extends JFrame {
    private static final int TILE_SIZE = 50; // 瓷砖大小
    private static final int NUM_TILES = 8; // 瓷砖数量

    public TileMaker() {
        setTitle("瓷砖制作");
        setSize(NUM_TILES * TILE_SIZE, NUM_TILES * TILE_SIZE);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLocationRelativeTo(null);
    }

    public void paint(Graphics g) {
        super.paint(g);
        for (int i = 0; i < NUM_TILES; i++) {
            for (int j = 0; j < NUM_TILES; j++) {
                if ((i + j) % 2 == 0) {
                    g.setColor(Color.WHITE);
                } else {
                    g.setColor(Color.BLACK);
                }
                g.fillRect(i * TILE_SIZE, j * TILE_SIZE, TILE_SIZE, TILE_SIZE);
            }
        }
    }

    public static void main(String[] args) {
        EventQueue.invokeLater(() -> {
            TileMaker tileMaker = new TileMaker();
            tileMaker.setVisible(true);
        });
    }
}
