如何在java中声明一个具有两个或多个单数组的多维数组变量？

Question

是否可以使用许多简单的数组值来声明多维数组值？

char[] alpha1 = {"A","B","C","D","E"}; 
char[] alpha2 = {"F","G","H","I","J"}; 
//Is it possible? Give me a solution for this situation: 
char[][] alpha = { alpha1[] , alpha2[] }; 

Answer 1

随着" "你声明一个字符串。使用' '作为角色。

但是是有可能的，但你必须删除[]：

char[] alpha1 = {'A','B','C','D','E'}; 
char[] alpha2 = {'F','G','H','I','J'}; 
char[][] alpha = { alpha1 , alpha2 }; 

Answer 2

有一对夫妇的方式来声明多维数组：

1. 的char [] []的α= {{ 'A'，'B'，'C'，'D'，'E'}，{'F'，'G'，'H'，'I'，'J'}};
2. char [] [] alpha = new char [4] []; alpha [0] = new char [3]; alpha [1] = new char [2];
