五子棋源代码用JAVA实现

以下是一个简单的五子棋游戏的源代码，使用 Java 语言实现：

import java.util.Scanner;

public class FiveChess {
    private int boardSize = 15;  // 棋盘大小
    private int[][] board = new int[boardSize][boardSize];  // 棋盘数组
    private int current_player = 1;  // 当前玩家

    public void put_chess(int x, int y) {
        if (x < 0 || x >= boardSize || y < 0 || y >= boardSize) {
            System.out.println("输入不合法，请重新输入！");
            return;
        }
        if (board[x][y] != 0) {
            System.out.println("此处已有棋子，请重新输入！");
            return;
        }
        board[x][y] = current_player;
    }

    public boolean check_win(int x, int y) {
        int[][] directions = {{0, 1}, {1, 0}, {1, 1}, {1, -1}};
        for (int[] d : directions) {
            int count = 1;
            int dx = d[0], dy = d[1];
            int tx = x+dx, ty = y+dy;
            while (tx >= 0 && tx < boardSize && ty >= 0 && ty < boardSize && board[tx][ty] == current_player) {
                count++;
                tx += dx;
                ty += dy;
            }
            dx = -d[0];
            dy = -d[1];
            tx = x+dx;
            ty = y+dy;
            while (tx >= 0 && tx < boardSize && ty >= 0 && ty < boardSize && board[tx][ty] == current_player) {
                count++;
                tx += dx;
                ty += dy;
            }
            if (count >= 5) {
                return true;
            }
        }
        return false;
    }

    public void play() {
        Scanner scanner = new Scanner(System.in);
        while (true) {
            System.out.println("当前玩家：" + (current_player == 1 ? "黑方" : "白方"));
            System.out.print("请输入棋子的横坐标：");
            int x = scanner.nextInt();
            System.out.print("请输入棋子的纵坐标：");
            int y = scanner.nextInt();
            put_chess(x, y);
            if (check_win(x, y)) {
                System.out.println((current_player == 1 ? "黑方" : "白方") + "获胜！");
                break;
            }
            current_player = -current_player;
        }
        scanner.close();
    }

    public static void main(String[] args) {
        FiveChess game = new FiveChess();
        game.play();
    }
}

运行该程序，即可开始五子棋游戏。
