如何将5个1D数组转换为2D数组

Question

因此，我必须创建一个这样做的宾果板，不要介意长代码对于第一列方法而言是重复的。 所以我想将这5个1D数组转换为1个2D数组，以便我可以检查宾果游戏。 有人可以详细向我解释我如何将这5个数组转换为1个2D数组，或者是否有可能检查5个1D数组。

Answer 1

int[] first = null;
int[] second = null;
int[] third = null;
int[] fourth = null;
int[] fifth = null;


int[][] arr2d = new int[][]{first , second , third , fourth , fifth};
