前言

相对于推箱子游戏，五子棋游戏加入了判断方法，即是否五子连棋。

---

一、Java二维数组

通过对Java二维数组的创建、修改、打印和字符判断实现五子棋游戏。

二、实现方法

1.引入库

代码如下：

import java.util.Scanner;

2.创建棋盘

创建长度11*11棋盘，代码如下：

 String[][] arr = new String[11][11];
        arr[0] = new String[] {" 0"," 1"," 2"," 3"," 4"," 5"," 6"," 7"," 8"," 9"," 10"};
        arr[1]=new String []{" 1"," -"," -"," -"," -"," -"," -"," -"," -"," -"," -"};
        arr[2] =new String[]{" 2"," -"," -"," -"," -"," -"," -"," -"," -"," -"," -"};
        arr[3] =new String[]{" 3"," -"," -"," -"," -"," -"," -"," -"," -"," -"," -"};
        arr[4] =new String[]{" 4"," -"," -"," -"," -"," -"," -"," -"," -"," -"," -"};
        arr[5] =new String[]{" 5"," -"," -"," -"," -"," -"," -"," -"," -"," -"," -"};
        arr[6] =new String[]{" 6"," -"," -"," -"," -"," -"," -"," -"," -"," -"," -"};
        arr[7] =new String[]{" 7"," -"," -"," -"," -"," -"," -"," -"," -"," -"," -"};
        arr[8] =new String[]{" 8"," -"," -"," -"," -"," -"," -"," -"," -"," -"," -"};
        arr[9] =new String[]{" 9"," -"," -"," -"," -"," -"," -"," -"," -"," -"," -"};
        arr[10] =new String[]{"10"," -"," -"," -"," -"," -"," -"," -"," -"," -"," -"};
        print(arr);

3.创建黑白落子行为函数

数组内容替换，将“-”替换为“黑”或者“白”，代码如下：

static void black(String [] [] arr,Scanner sc) //黑棋落子
    {
        System.out.println("请输入黑子坐标：");
        int blackx =sc.nextInt();
        int blacky=sc.nextInt();
        if(blackx<=10&blacky<=10&blackx>=1&blacky>=1)
        {
            if(arr[blacky][blackx]==" -")
            {
                arr[blacky][blackx]="黑";
                print(arr);
            }
            else
            {
                System.out.println("此处有子！！");
                print(arr);
            }    
        }

    }
    static void white(String[][] arr,Scanner sc) //白棋落子
    {
        System.out.println("请输入白子坐标：");
            int whitex =sc.nextInt();
            int whitey=sc.nextInt();
            if(whitex<=10&whitey<=10&whitex>=1&whitey>=1)
            {
                if(arr[whitey][whitex]==" -")
                {
                    arr[whitey][whitex]="白";
                    print(arr);
                }
                else
                {
                    System.out.println("此处有子！！");
                    print(arr);
                }
            }
    }

4.遍历数组，判断是否五子连棋

数组长度一致，判断横竖和对角线是否五个字符一致，代码如下：

static boolean judge(String [][] arr,String color) //五子连棋判断
    {
        boolean x=false;
        for (int i=1;i<=arr.length-3;i++)
        {
            for(int j=3;j<=arr[i].length-3;j++)
            {
                if(arr[i][j]==arr[i][j+1]&arr[i][j+2]==arr[i][j]&arr[i][j]==arr[i][j-1]&arr[i][j-2]==arr[i][j]&arr[i][j]==color)
                {
                    System.out.println(color+"子"+"胜利！！！");
                    x=true;
                }   
            }
        }
        for(int i=3;i<=arr.length-3;i++)
        {
            for(int j=1;j<arr.length;j++)
            {
                if(arr[i][j]==arr[i+1][j]&arr[i+2][j]==arr[i][j]&arr[i][j]==arr[i-1][j]&arr[i][j]==arr[i-2][j]&arr[i][j]==color)
                {
                    System.out.println(color+"子"+"胜利！！！");
                    x=true;
                }
            }
        }
        for(int i=3;i<=arr.length-3;i++)
        {
            for(int j=3;j<=arr.length-3;j++)
            {
                if(arr[i][j]==arr[i+1][j+1]&arr[i+2][j+2]==arr[i][j]&arr[i-1][j-1]==arr[i][j]&arr[i-2][j-2]==arr[i][j]&arr[i][j]==color)
                {
                    System.out.println(color+"子"+"胜利！！！");
                    x=true; 
                }
            }
        }
        for(int i=3;i<=arr.length-3;i++)
        {
            for(int j=3;j<=arr.length-3;j++)
            {
                if(arr[i][j]==arr[i-1][j+1]&arr[i-2][j+2]==arr[i][j]&arr[i+1][j-1]==arr[i][j]&arr[i+2][j-2]==arr[i][j]&arr[i][j]==color)
                {
                    System.out.println(color+"子"+"胜利！！！");
                    x=true; 
                }
            }
        }
        return x;    
    }

---

5.创建main主函数

main函数为一循环，黑白双方轮流落子，当黑或白连成五子时，跳出循环，游戏结束。代码如下：

ko:
        for(int num=1;num<=100;num++)
        {
            Scanner sc=new Scanner(System.in);
            white(arr,sc);
            if (judge(arr,"白")==true)
            {break ko;}
            black(arr,sc);
            if (judge(arr,"黑") ==true)
            {break ko;}
        }

---

6.测试效果

总结

跳出循环的方法 使用xx:为循环命名，当满足条件后使用break xx;跳出循环。
