Java上多维数组的配置

Question

谁先考虑？[列][行]或[行][列]

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

[row][col]的顺序正确，因此[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

我希望这就是你想要的

Answer 2

java多维数组中的default是arrays[column][row]

甚至您也可以在代码中按顺序进行操作

例如，您希望先打印行，然后打印列
