1、JAVA面向对象程序设计实验指导代码内容简介 本书是Java面向对象程序设计的配套实验指导和习题解答。本书的第一部分为16次上机实践的内容，每次上机实践由若干个实验组成。每个实验由相关知识点、实验目的、实验要求、实验模版、实验知道和实验报告组成。在进行实验之前，首先通过实验目的了解实验要完成的关键主题、通过实验要求知道本实验应达到怎样的标准，然后，完成实验模板，填写实验报告。本书的第二部分为主教材的习题参考解答。上机实践1 Java入门实验1 一个简单的应用程序5程序模板Hello.javapublic class Hello public static void main (String a
