package com.test.reflection;import java.lang.reflect.Array;public class ArrayTest1{public static void main(String[] args) throws Exception{Class<?> clazz = Class.forName("java.lang.String");//创建一个长度为10的字符串数组Object array = Array.newInstance(clazz, 10);//把索引位置为10的元素设为“Hello Word”；Array.set(array, 9, "Hello Word");//获取索引位置10的元素的值String reuslt = (String) Array.get(array, 9);System.out.println("Result is + " + reuslt);}}
