Educoder-学习-Java数组之二维字符数组之按字母序排序

脑袋大，等我缓缓

import java.util.Arrays;

public class Transpose {
    public static void main(String[] args) {
        // 定义二维数组并初始化
        char[][] a = {{'d','v','g','r'},{'h','s','r','a'},{'q','e','t','z'},{'o','p','d','s'}};

        for (int i = 0; i < 4 ;i++){
            for (int j = 0; j < 4; j++){
                int n = j + 1;
                for (int m = i; m < 4; m++){
                    for (;n < 4; n++){
                        if (a[i][j] < a[m][n]){
                            char max = a[m][n];
                            a[m][n] = a[i][j];
                            a[i][j] = max;
                        }
                    }
                    n = 0;      //此处是给n从第二个一维数组开始取0这个坐标
                }
            }
        }
        for (int i = 0; i < 4; i++){
            for (int j = 0; j < 4; j++){
                System.out.print(a[i][j] + " ");
            }
            System.out.println();
        }   
    }
}
