如何在Java中使用两个或多个单个数组声明多维数组变量？

Question

Is it possible to use many simple array values to declare as multidimensional array values?

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

With " " you declare a String. Use ' ' for a character.

But yes it is possible, but you have to remove [] :

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

Answer 2

There are a couple of ways to declare multidimensional array:

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];
