java实现五子棋游戏

以下是 Java 实现五子棋游戏的简单步骤：

1. 创建一个棋盘类（Board），在棋盘上绘制出 15×15 的网格。

2. 定义一个棋子类（Piece），包括棋子的颜色和位置。

3. 创建一个游戏类（Game），它包括一个棋盘和两个玩家。可以通过键盘输入或鼠标点击来落子。

4. 实现落子规则，每当一个玩家下完一步棋后，判断是否有五个同色棋子相连，如果有则该玩家获胜。

5. 实现 AI 玩家，让计算机能够下棋。可以使用简单的算法，如随机下棋或简单的搜索算法。

以下是示例代码：

棋盘类 Board：

public class Board {
    private int[][] grid;

    public Board() {
        grid = new int[15][15];
    }

    public void draw() {
        // 绘制棋盘
    }

    public boolean isValidMove(int x, int y) {
        // 判断落子是否合法
    }

    public void placePiece(Piece piece) {
        // 在棋盘上放置棋子
    }

    public boolean checkWin(Piece piece) {
        // 判断是否获胜
    }
}

棋子类 Piece：

public class Piece {
    private int x;
    private int y;
    private int color;

    public Piece(int x, int y, int color) {
        this.x = x;
        this.y = y;
        this.color = color;
    }

    public int getX() {
        return x;
    }

    public int getY() {
        return y;
    }

    public int getColor() {
        return color;
    }
}

游戏类 Game：

import java.util.Scanner;

public class Game {
    private Board board;
    private Player player1;
    private Player player2;
    private Player currentPlayer;

    public Game() {
        board = new Board();
        player1 = new Player("Player 1", 1);
        player2 = new AIPlayer("AI", 2);
        currentPlayer = player1;
    }

    public void start() {
        while (true) {
            board.draw();
            System.out.println(currentPlayer.getName() + " turn.");
            int x, y;
            if (currentPlayer instanceof AIPlayer) {
                x = ((AIPlayer) currentPlayer).getNextMove(board);
                y = ((AIPlayer) currentPlayer).getNextMove(board);
                System.out.println("AI placed a piece at (" + x + ", " + y + ")");
            } else {
                Scanner scanner = new Scanner(System.in);
                System.out.print("Enter x: ");
                x = scanner.nextInt();
                System.out.print("Enter y: ");
                y = scanner.nextInt();
            }
            Piece piece = new Piece(x, y, currentPlayer.getColor());
            if (board.isValidMove(x, y)) {
                board.placePiece(piece);
                if (board.checkWin(piece)) {
                    System.out.println(currentPlayer.getName() + " wins!");
                    break;
                }
                currentPlayer = (currentPlayer == player1) ? player2 : player1;
            } else {
                System.out.println("Invalid move.");
            }
        }
    }
}

玩家类 Player：

public class Player {
    private String name;
    private int color;

    public Player(String name, int color) {
        this.name = name;
        this.color = color;
    }

    public String getName() {
        return name;
    }

    public int getColor() {
        return color;
    }
}

AI 玩家类 AIPlayer：

import java.util.Random;

public class AIPlayer extends Player {
    private Random random;

    public AIPlayer(String name, int color) {
        super(name, color);
        random = new Random();
    }

    public int getNextMove(Board board) {
        int x = random.nextInt(15);
        int y = random.nextInt(15);
        while (!board.isValidMove(x, y)) {
            x = random.nextInt(15);
            y = random.nextInt(15);
        }
        return x;
    }
}

以上是一个基本的五子棋游戏实现，可以根据需求进行修改和扩展。
