用Java实现一个GUI模式的五子棋游戏

以下是一个基本的Java GUI五子棋游戏实现。我们使用Swing库来构建GUI界面。

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

public class Gobang extends JFrame implements ActionListener{

    private static final long serialVersionUID = 1L;
    private final int ROWS = 15;
    private final int COLS = 15;
    private final int GAP = 30; 
    private final int WIDTH = COLS * GAP + 50;
    private final int HEIGHT = ROWS * GAP + 70;
    private JButton[][] board;
    private int[][] data;
    private int currentPlayer = 1; 
    
    public Gobang() {
        setTitle("五子棋");
        setSize(WIDTH, HEIGHT);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLocationRelativeTo(null);
        setResizable(false);
        initBoard();
        setVisible(true);
    }
    
    private void initBoard() {
        JPanel p = new JPanel();
        p.setLayout(new GridLayout(ROWS, COLS));
        board = new JButton[ROWS][COLS];
        data = new int[ROWS][COLS];
        for (int i = 0; i < ROWS; i++) {
            for (int j = 0; j < COLS; j++) {
                board[i][j] = new JButton();

                board[i][j].addActionListener(this);
                p.add(board[i][j]);
                data[i][j] = 0;
            }
        }
        add(p, BorderLayout.CENTER);
    }
    
    public void actionPerformed(ActionEvent e) {

            for (int j = 0; j < COLS; j++) {

                        board[i][j].setBackground(currentPlayer == 1 ? Color.BLACK : Color.WHITE);
                        data[i][j] = currentPlayer;
                        if (checkWin(i, j)) {
                            JOptionPane.showMessageDialog(this, "玩家 " + currentPlayer + " 获胜！");
                            System.exit(0);
                        }
                        currentPlayer = currentPlayer == 1 ? 2 : 1;
                    }
                }
            }
        }

        int count = 1;
        int r, c;
        //检查横向
        for (int i = col - 1; i >= 0; i--) {

        }
        //检查左上-右下斜线
        count = 1;
        r = row - 1;
        c = col - 1;
        while (r >= 0 && c >= 0) {
            if (data[r][c] == currentPlayer) {
                count++;
            } else {
                break;
            }
            r--;
            c--;
        }
        r = row + 1;
        c = col + 1;
        while (r < ROWS && c < COLS) {
            if (data[r][c] == currentPlayer) {

        }
        if (count >= 5) {
            return true;
        }
        return false;

    public static void main(String[] args) {
        new Gobang();
    }
}

我们首先定义了一个15x15的棋盘，使用了一个二维数组来存储每个位置的状态。玩家可以通过点击棋盘上的按钮来下棋。每次点击后，我们会检查当前玩家是否获胜，如果是，我们会弹出一个提示框。

在checkWin()方法中，我们会检查是否有5个同色棋子连成一线，如果是，返回true，否则返回false。

这只是一个简单的五子棋游戏实现，你可以根据自己的需求对其进行扩展和优化。
