 1 package com.pingfan.array;
 2 
 3 public class ArrayDemo2 {
 4     public static void main(String[] args) {
 5         //静态初始化：创建 + 赋值
 6         int[] a ={1,2,3,4,5,6,7,8};
 7         System.out.println(a[0]);
 8         //动态初始化：包含默认初始化
 9         int[] b = new int[10];
10         b[0] = 10;
11         b[1] = 10;
12         System.out.println(b[0]);
13         System.out.println(b[1]);
14         System.out.println(b[2]);
15         System.out.println(b[3]);
16         System.out.println(b[4]);
17     }
