如何在java中声明一个包含两个或更多单个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为多维数组值？

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

使用" "声明一个String。使用' '作为角色。

但是有可能，但您必须删除[]：

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

Answer 2

有几种方法可以声明多维数组：

1. char [] [] alpha = {{'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];
