标题: 二维数组相关题目

1. char[][]arr = new char[][]{{"8","5","0","1","3"},{"3","2","3","9"},{"10","11","4","8"},{"1","4","1"}};//这样写报错又是什么原因啊？
   

复制代码

char[][]arr = new char[][]{{'8','5','0','1','3'},{'3','2','3','9'},{'10','11','4','8'},{'1','4','1'}};
想这样创建二维数组就报错了

但是这样就不会报错 int[][]arr = new int[][]{{8,5,0,1,3},{3,2,3,9},{10,11,4,8},{1,4,1 }};
有谁知道为什么？

1. char[][]arr = new char[][]{{'8','5','0','1','3'},{'3','2','3','9'},{'10','11','4','8'},{'1','4','1'}};//想这样写会报错，有谁知道为什么不？

注意你的10，11不是一个字符。{'10','11','4','8'}

大哥，你把字符数组里面存字符串，你疯了，唉，多注意细节吧
