一、内容简介：

五子棋小游戏是我们日常生活中经常玩的小游戏，游戏规则也很简单。下面就让我们使用Java来实现五子棋的编写吧！

二、基本流程

1.通过菜单选择开始游戏和退出游戏
2.创建并初始化棋盘为空格
3.打印棋盘
4.玩家以坐标的形式落子
5.判断输赢

三、具体步骤

1.菜单栏

public static void menu() {System.out.println("-------------------------------------------------------");System.out.println("---------------1.开始游戏      2.退出游戏----------------");System.out.println("-------------------------------------------------------");}

2.创建棋盘并初始化为空格

(1)定义行数、列数为常量

public static final int ROW = 10;//行数
public static final int COL = 10;//列数
public static final String BlackChess = "#";//黑方
public static final String WhiteChess = "*";//白方

(2)定义棋盘

String[][] board = new String[ROW + 1][COL + 1];

多的一行、一列为了添加坐标使用。

(3)给棋盘添加坐标并初始化棋盘为空格

	/*** 给棋盘添加坐标并初始化棋盘为空格** @param board 棋盘* @param row   行数* @param col   列数*/private static void InitBoard(String[][] board, int row, int col) {String[] arr = {"1 ", "2 ", "3 ", "4 ", "5 ", "6 ", "7 ", "8 ", "9 ", "10"};board[row] = arr;for (int i = 0; i < arr.length; i++) {board[i][col] = arr[i];}for (int i = 0; i < row; i++) {for (int j = 0; j < col; j++) {board[i][j] = " ";}}System.out.println();}}

3.打印棋盘

	/*** 打印棋盘* @param board 棋盘* @param row   行数* @param col   列数*/private static void PrintBoard(String[][] board, int row, int col) {for (int i = 0; i < row; i++) {for (int j = 0; j < col + 1; j++) {System.out.printf(" %s ", board[i][j]);if (j < col)System.out.print("|");}System.out.println();if (i < row - 1) {for (int j = 0; j < col + 1; j++) {System.out.print("---");if (j < col)System.out.print("|");}System.out.println();}}for (int j = 0; j < col; j++) {System.out.printf(" %s", board[row][j]);if (j < col - 1)System.out.print("|");}}

4.玩家落子

	/*** 玩家落子** @param board //棋盘* @param x     //横坐标* @param y     //纵坐标* @param Chess //棋子* @param row   // 行数* @param col   // 列数*/private static boolean PlayerMove(String[][] board, int x, int y, String Chess, int row, int col) {while (true) {if (x >= 0 && x < row && y >= 0 && y < col) {if (board[x][y].equals(" ")) {board[x][y] = Chess;return false;} else {System.out.println("该坐标已被占用！");return true;}} else {System.out.println("坐标非法，请您重新输入！");return true;}}}

如果落子成功，返回false，不进入外面的循环；如果落子失败，返回true，进入外面的循环，重新落子。

5.判断输赢

1.判断横着或竖着是否有连续的相同的5颗棋子，这个比较容易实现。
2.判断斜着是否有连续的相同的5颗棋子。
将下的这颗棋子为中心，分别判断它的左上、右下和左下、右上是否有连续的相同的5颗棋子。

	 /*** @param board     //棋盘* @param x         //横坐标* @param y         //纵坐标* @param Chess//棋子* @param row       //行数* @param col       //列数* @return //true或false*/private static boolean IsWin(String[][] board, int x, int y, String Chess, int row, int col) {//判断横或竖是否有相同的五颗棋for (int i = 0; i < row - 5; i++) {if (board[x][i].equals(Chess) && board[x][i + 1].equals(Chess) && board[x][i + 2].equals(Chess)&& board[x][i + 3].equals(Chess)&& board[x][i + 4].equals(Chess))return true;if (board[i][y].equals(Chess) && board[i + 1][y].equals(Chess) && board[i + 2][y].equals(Chess)&& board[i + 3][y].equals(Chess)&& board[i + 4][y].equals(Chess))return true;}//判断该棋子的左上、右下和左下、右上是否有连续的相同的五颗棋子int count1 = 1;int count2 = 1;int lx, ly;//左上for (lx = x - 1, ly = y + 1; lx >= 0 && ly >= 0; lx--, ly--) {if (board[lx][ly].equals(Chess)) {count1++;if (count1 >= 5)return true;} else {break;}}//右下for (lx = x + 1, ly = y - 1; lx >= 0 && ly >= 0; lx--, ly--) {if (board[lx][ly].equals(Chess)) {count1++;if (count1 >= 5)return true;} else {break;}}//左下for (lx = x - 1, ly = y - 1; lx >= 0 && ly >= 0; lx--, ly--) {if (board[lx][ly].equals(Chess)) {count2++;if (count2 >= 5)return true;} else {break;}}//右上for (lx = x + 1, ly = y + 1; lx >= 0 && ly >= 0; lx--, ly--) {if (board[lx][ly].equals(Chess)) {count2++;if (count2 >= 5)return true;} else {break;}}return false;//没有人赢}

四、代码实现

import java.util.Scanner;public class Main {public static final int ROW = 10;//行数public static final int COL = 10;//列数public static final String BlackChess = "#";public static final String WhiteChess = "*";public static void main(String[] args) {Scanner sca = new Scanner(System.in);menu();System.out.println("请您输入选择：");int input = sca.nextInt();while (true) {switch (input) {case 1://开始游戏beginGame(sca);break;case 2://退出游戏endGame();break;default:System.out.println("非法输入！");System.out.println("请您重新输入！");}break;}}/*** 退出游戏*/private static void endGame() {System.out.println("您已退出游戏！");return;}public static void menu() {System.out.println("-------------------------------------------------------");System.out.println("---------------1.开始游戏      2.退出游戏----------------");System.out.println("-------------------------------------------------------");}public static void beginGame(Scanner sca) {//1.定义棋盘String[][] board = new String[ROW + 1][COL + 1];//2.给棋盘添加坐标并初始化棋盘为空格InitBoard(board, ROW, COL);//3.打印棋盘PrintBoard(board, ROW, COL);/*** 开始下棋*/while (true) {boolean flag = true;//4.黑方落子System.out.println();int x = 0, y = 0;System.out.println("请黑方落子：");x = sca.nextInt() - 1;y = sca.nextInt() - 1;while (PlayerMove(board, x, y, BlackChess, ROW, COL)) {System.out.println("请重新输入！");x = sca.nextInt() - 1;y = sca.nextInt() - 1;}PrintBoard(board, ROW, COL);//打印棋盘//5.判断输赢boolean winer = IsWin(board, x, y, BlackChess, ROW, COL);if (winer) {System.out.println();System.out.println("黑方胜！");System.out.println("游戏结束！");break;}//6.白方落子System.out.println();System.out.println("请白方落子");x = sca.nextInt() - 1;y = sca.nextInt() - 1;while (PlayerMove(board, x, y, WhiteChess, ROW, COL)) {System.out.println("请重新输入！");x = sca.nextInt() - 1;y = sca.nextInt() - 1;}PrintBoard(board, ROW, COL);//打印棋盘//判断输赢if (IsWin(board, x, y, WhiteChess, ROW, COL)) {System.out.println();System.out.println("白方胜！");System.out.println("游戏结束！");break;}}return;}/*** 玩家落子** @param board //棋盘* @param x     //横坐标* @param y     //纵坐标* @param Chess //棋子* @param row   // 行数* @param col   // 列数*/private static boolean PlayerMove(String[][] board, int x, int y, String Chess, int row, int col) {while (true) {if (x >= 0 && x < row && y >= 0 && y < col) {if (board[x][y].equals(" ")) {board[x][y] = Chess;return false;} else {System.out.println("该坐标已被占用！");return true;}} else {System.out.println("坐标非法，请您重新输入！");return true;}}}/*** @param board     //棋盘* @param x         //横坐标* @param y         //纵坐标* @param Chess//棋子* @param row       //行数* @param col       //列数* @return //true或false*/private static boolean IsWin(String[][] board, int x, int y, String Chess, int row, int col) {//判断横或竖是否有相同的五颗棋for (int i = 0; i < row - 5; i++) {if (board[x][i].equals(Chess) && board[x][i + 1].equals(Chess) && board[x][i + 2].equals(Chess)&& board[x][i + 3].equals(Chess)&& board[x][i + 4].equals(Chess))return true;if (board[i][y].equals(Chess) && board[i + 1][y].equals(Chess) && board[i + 2][y].equals(Chess)&& board[i + 3][y].equals(Chess)&& board[i + 4][y].equals(Chess))return true;}//判断该棋子的左上、右下和左下、右上是否有连续的相同的五颗棋子int count1 = 1;int count2 = 1;int lx, ly;//左上for (lx = x - 1, ly = y + 1; lx >= 0 && ly >= 0; lx--, ly--) {if (board[lx][ly].equals(Chess)) {count1++;if (count1 >= 5)return true;} else {break;}}//右下for (lx = x + 1, ly = y - 1; lx >= 0 && ly >= 0; lx--, ly--) {if (board[lx][ly].equals(Chess)) {count1++;if (count1 >= 5)return true;} else {break;}}//左下for (lx = x - 1, ly = y - 1; lx >= 0 && ly >= 0; lx--, ly--) {if (board[lx][ly].equals(Chess)) {count2++;if (count2 >= 5)return true;} else {break;}}//右上for (lx = x + 1, ly = y + 1; lx >= 0 && ly >= 0; lx--, ly--) {if (board[lx][ly].equals(Chess)) {count2++;if (count2 >= 5)return true;} else {break;}}return false;//没有人赢}/*** 打印棋盘* @param board 棋盘* @param row   行数* @param col   列数*/private static void PrintBoard(String[][] board, int row, int col) {for (int i = 0; i < row; i++) {for (int j = 0; j < col + 1; j++) {System.out.printf(" %s ", board[i][j]);if (j < col)System.out.print("|");}System.out.println();if (i < row - 1) {for (int j = 0; j < col + 1; j++) {System.out.print("---");if (j < col)System.out.print("|");}System.out.println();}}for (int j = 0; j < col; j++) {System.out.printf(" %s", board[row][j]);if (j < col - 1)System.out.print("|");}}/*** 给棋盘添加坐标并初始化棋盘为空格** @param board 棋盘* @param row   行数* @param col   列数*/private static void InitBoard(String[][] board, int row, int col) {String[] arr = {"1 ", "2 ", "3 ", "4 ", "5 ", "6 ", "7 ", "8 ", "9 ", "10"};board[row] = arr;for (int i = 0; i < arr.length; i++) {board[i][col] = arr[i];}for (int i = 0; i < row; i++) {for (int j = 0; j < col; j++) {board[i][j] = " ";}}System.out.println();}}
