数组初始化，哪里不对呢？

Question

int next[][][] = new int[][][]{};
    int next[0][][] = new int[0][][]{
                               {0,1,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0},
                               {1,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},
                               {0,1,0,1,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0},
                               {0,0,1,0,1,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0},
                               {0,0,0,1,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},
                               {0,0,0,0,1,0,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0},
                               {0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},
                               {0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},
                               {0,0,0,1,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0},

                               {0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0},
                               {0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0},
                               {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0},
                               {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,1,0},
                               {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,1},
                               {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,0}
                           };

Answer 1

you need to specify the array size when you declare it.

Answer 2

还有这个函数    public int[][] setdata(int i)
    {
        return next[i][][];
    }
怎么弄呢？很菜的问题，不知到哪里找。谢谢帮忙了。

Answer 3

2维不就可以了。
int next[][] = new int[][]{
  //你上面的数据
}另外，你上面的函数显然是getdata

Answer 4

前面三维数组有什么用么？？
没有的话用2维取吧
报错是因为你数组初始化没定size

Answer 5

二维数组的初始化：
int next[][]=new int[][]{{1,2},{2,1}},
三维数组的初始化：
int next[][][]=new int[][][]{{{1,2},{2,1}},{{3,4},{5,6}}},楼主的数组是三维数组,但赋值的时候却用了二维数组的赋值方式,所以发生错误.你可以:
1.把数组变成二维数组
或
2.按照三维数组的赋值方式赋值
