java求救，这题怎么编

1. 把二维数组当作是一维的：

在鸡西等地区，都构建了全面的区域性战略布局，加强发展的系统性、市场前瞻性、产品创新能力，以专注、极致的服务理念，为客户提供成都网站建设、网站制作 网站设计制作按需搭建网站,公司网站建设,企业网站建设,成都品牌网站建设,网络营销推广,外贸网站建设,鸡西网站建设费用合理。

例: 有数组char[3][3], 如 char[2][2]可以下标对应的数值为2×3 + 2 = 8，这个应该是第三行第三列的数据下标

2. 使用随机数生成器生成一定范围的下标（例如，0～8），反算数组中的位置，这个位置作为下子的地方。（下子就是把对应的数组中设成黑子或者白子）

3. 循环第二步，直至放满

（注意，可能会产生重复下标，需要先判断看看有没有已经有棋子在其上）
