标签：mamicode print generated 动态 输出 java i++ sum oid 编写一个简单程序，要求数组长度为5，动态赋值，并在控制台输出该数组的值。 3.定义字符型数组，分别存储c、h、 i、n、a 并在控制台输出 5.定义数组{12,53,23,44,53} 用for和foreach分别输出，再倒序输出 6.定义一个整型数组，赋值(动态静态都可以)后求出奇数个数和偶数个数 定义一个整型数组，赋值后求出奇数个数和偶数个数 生成一个100长度数组，里面的数分别是1-100，并输出 java7 标签：mamicode print generated 动态 输出 java i++ sum oid 原文地址：https://www.cnblogs.com/gxl920/p/14682383.html
