如何在java中聲明一個具有兩個或多個單數組的多維數組變量？

Question

是否可以使用許多簡單的數組值來聲明多維數組值？

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

隨着" "你聲明一個字符串。使用' '作爲角色。

但是是有可能的，但你必須刪除[]：

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

Answer 2

有一對夫婦的方式來聲明多維數組：

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];
