int a[][]=new int[3][3];

for (int j = 0; j a.length; j++) {
a[i][j]=(int)(Math.random()*2);

for (int j = 0; j a.length; j++) {
x++;
System.out.print(a[i][j]+" ");
if(x%3==0)
System.out.println();
}
}
判断的话if（a[0][0]==a[0][2]==a[0][1])等等都写上就行了
我说下我的想法:
看坐标: 横坐标一致
或纵坐标一致
还有就是/.\两种情况下 固定的位置你事先固定好
当三个点都有了棋子就一直线
以前写过一个java的井字棋 ,
其中的重点是要判断每走一步后,是否有比赛的结果(输,赢,平)
可以使用swing 来作为外观进行显示.
表示棋盘如下
0 1 2
3 4 5
6 7 8
定义一个二维数组,每次走完后,匹配该数组, 如果匹配成功就赢了
int[][] WIN = { { 0, 1, 2 }, { 3, 4, 5 }, { 6, 7, 8 }, { 0, 3, 6 }, { 1, 4, 7 }, { 2, 5, 8 }, { 0, 4, 8 },
{ 2, 4, 6 } };
效果图
当然了,因为井字棋比较简单, 可以写一个比较简单的判断局势,然后自动下棋的AI .
(AI使用了很多的if else判断, 比如人现在的情况是什么样的,有几个棋子连在一起了,电脑自己的情况是怎么样的)
