私はいつか Java でチェス ゲームを自分で作成し、使用したコードを見つけました。
だからここにあなたを始めるための何かがあります：
チェス盤テスト:
public class ChessBoardTest {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
try {
Image blackBlock=ImageIO.read(new File("c:/bblock.jpg"));
Image whiteBlock=ImageIO.read(new File("c:/wblock.jpg"));
Board board = new Board(whiteBlock,blackBlock);
//add pieces to board
board.addPiece(new ImageIcon("c:/castle.jpg"), "A1");//just one example
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
Board.java:
import java.awt.*;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

実際には、オンラインの roseindia で非常に合理的な例があります。
