在Java上配置多维数组

Question

哪个先考虑?[col][row]还是[row][col]?

public class multiDiArray {
    public static void main(String[] args) {
        char [][] name = {  
                {'A','B','C','D','Q'},
                {'E','F','G','H','R'},
                {'I','J','K','L','S'},
                {'M','N','O','P','T'},
                {'U','V','W','X','Y'}
        };
        System.out.println(name[1][0]);  // shows J
        /*System.out.println(name[0][0]);  // shows A
        System.out.println(name[3][1]);  // shows N
        System.out.println(name[3][1]);  // shows N
        System.out.println(name[0][0]);  // shows A  
        System.out.println(name[3][4]);  // shows T
        System.out.println(name[2][0]);  // shows I
        System.out.println(name[3][1]);  // shows N
        */
    }
}

Answer 1

(行)(col)是正确的顺序,所以[0][0]= A [1] [0] = E [0] [1] = B

0 {'A','B','C','D','Q'},
1 {'E','F','G','H','R'},
2 {'I','J','K','L','S'},
3 {'M','N','O','P','T'},
4 {'U','V','W','X','Y'}
    0   1   2   3   4

我希望这就是你要找的

Answer 2

java默认多维数组为arrays[column][row].

你甚至可以在代码中使用顺序

例如，您想先打印行再打印列。
