Java代码如何打印一个二维数组呢?

实现思路:
    使用两个for循环
	即可输出一个二维数组

package com.java265;
 
public class ArrayExample {
 
    public static void main(String[] args) {
 
        //二维数组定义方式1 
        int[][] num2d = new int[2][3];
 
        num2d[0][0] = 88;
        num2d[0][1] = 99;
        num2d[0][2] = 100;
 
        num2d[1][0] = 222;
        num2d[1][1] = 333;
        num2d[1][2] = 444;
 
        //二维数组定义方式2
        int[][] num2dInit = {
                {88,99,100},
                {222,333,444}
        };
 
        print2dArray(num2d);
    }
 
    static void print2dArray(int[][] num2d) {
        int index1d, index2d = 0;
 
        for (int[] num1d : num2d) {
            index1d = 0;
            for (int num : num1d) {
                System.out.println("[" + index2d + "][" + index1d + "] = " + num);
                index1d++;
            }
            index2d++;
        }
    }
}
