package com.karl1;

public class ArrayDemo2 {
    public static void main(String[] args) {
        //数组的遍历
        int[] ages = {12,24,36};
        //             0  1  2
        for (int i = 0; i < ages.length; i++) {
            System.out.println(ages[i]);

        }
        //快捷：数组名.fori+回车
    }
