Java GUI实现五子棋游戏

五子棋是一种双人对弈的棋类游戏，通常在棋盘上进行。棋盘为 15×15 的方格，黑白双方各执棋子，轮流在棋盘的格点上落子，先在横、竖、斜线上形成五个相连的同色棋子者获胜。五子棋规则简单，易学难精，兼具攻防和谋略，是一种极具智慧和趣味性的游戏。

以下是使用Java编写的五子棋游戏的示例代码：

棋盘类：

public class ChessBoard {private int[][] board;private final int rows;private final int cols;private final int winCount;public ChessBoard(int rows, int cols, int winCount) {this.rows = rows;this.cols = cols;this.winCount = winCount;board = new int[rows][cols];}public int getRows() {return rows;}public int getCols() {return cols;}public int getWinCount() {return winCount;}public int getChessman(int row, int col) {return board[row][col];}public boolean canPutChessman(int row, int col) {return board[row][col] == 0;}public void putChessman(int row, int col, int player) {board[row][col] = player;}public boolean isFull() {for (int i = 0; i < rows; i++) {for (int j = 0; j < cols; j++) {if (board[i][j] == 0) {return false;}}}return true;}public boolean hasWinner(int player) {for (int i = 0; i < rows; i++) {for (int j = 0; j < cols; j++) {if (board[i][j] == player) {if (checkHorizontal(i, j, player)) {return true;}if (checkVertical(i, j, player)) {return true;}if (checkDiagonal1(i, j, player)) {return true;}if (checkDiagonal2(i, j, player)) {return true;}}}}return false;}private boolean checkHorizontal(int row, int col, int player) {int count = 1;for (int j = col + 1; j < cols && board[row][j] == player; j++) {count++;}for (int j = col - 1; j >= 0 && board[row][j] == player; j--) {count++;}return count >= winCount;}private boolean checkVertical(int row, int col, int player) {int count = 1;for (int i = row + 1; i < rows && board[i][col] == player; i++) {count++;}for (int i = row - 1; i >= 0 && board[i][col] == player; i--) {count++;}return count >= winCount;}private boolean checkDiagonal1(int row, int col, int player) {int count = 1;for (int i = row + 1, j = col + 1; i < rows && j < cols && board[i][j] == player; i++, j++) {count++;}for (int i = row - 1, j = col - 1; i >= 0 && j >= 0 && board[i][j] == player; i--, j--) {count++;}return count >= winCount;}private boolean checkDiagonal2(int row, int col, int player) {int count = 1;for (int i = row + 1, j = col - 1; i < rows && j >= 0 && board[i][j] == player; i++, j--) {count++;}for (int i = row - 1, j = col + 1; i >= 0 && j < cols && board[i][j] == player; i--, j++) {count++;}return count >= winCount;}}

游戏界面类：

import java.awt.Color;
import java.awt.Graphics;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.JFrame;
import javax.swing.JPanel;public class GameUI extends JFrame {private final int rows;private final int cols;private final int winCount;private ChessBoard board;private int currentPlayer;private boolean gameOver;private final JPanel panel;public GameUI(int rows, int cols, int winCount) {this.rows = rows;this.cols = cols;this.winCount = winCount;setTitle("五子棋");setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);setSize(cols * 40, rows * 40); // 每个棋子为正方形，大小为40setLocationRelativeTo(null);currentPlayer = 1;board = new ChessBoard(rows, cols, winCount);gameOver = false;panel = new JPanel() {@Overridepublic void paintComponent(Graphics g) {super.paintComponent(g);for (int i = 0; i < rows; i++) {for (int j = 0; j < cols; j++) {int chessman = board.getChessman(i, j);if (chessman == 1) {g.setColor(Color.BLACK);g.fillOval(j * 40 + 5, i * 40 + 5, 30, 30);} else if (chessman == 2) {g.setColor(Color.WHITE);g.fillOval(j * 40 + 5, i * 40 + 5, 30, 30);g.setColor(Color.BLACK);g.drawOval(j * 40 + 5, i * 40 + 5, 30, 30);}}}}};panel.addMouseListener(new MouseAdapter() {@Overridepublic void mouseClicked(MouseEvent e) {if (gameOver) {return;}int col = e.getX() / 40;int row = e.getY() / 40;if (row < rows && col < cols && board.canPutChessman(row, col)) {board.putChessman(row, col, currentPlayer);panel.repaint();if (board.hasWinner(currentPlayer)) {gameOver = true;System.out.println("Player " + currentPlayer + " wins.");} else if (board.isFull()) {gameOver = true;System.out.println("Tie game.");} else {currentPlayer = 3 - currentPlayer; // 切换玩家}}}});add(panel);setVisible(true);}}

主程序：

public class Main {public static void main(String[] args) {new GameUI(15, 15, 5);}}

在主程序中创建游戏界面对象，传入行数、列数和获胜所需连续棋子个数，即可开始游戏。

效果如下：
