1、开发一个托盘程序操作系统实验报告年级、专业、班级2010级信安一班姓名 实验题目开发一个托盘程序实验时间 2013.4.23实验地点主教0416实验成绩 实验性质验证性 设计性 综合性教师评价：算法/实验过程正确； 源程序/实验内容提交 程序结构/实验步骤合理；实验结果正确； 语法、语义正确； 报告规范； 其他： 评价教师签名：一、实验目的1）了解操作系统API函数的结构和调用基本知识；2）会使用API函数。3）加强程序设计练习。二、实验项目内容在Windows环境下开发一个完整的托盘程序。程序功能：1）获取系统时间，每1秒钟刷新1次。2）获取CPU基本信息，至少包括：CPU主频，CPU序列号
2、，CPU型号3）获取内存信息，至少包括：内存总量，可用内存量三、实验过程或算法（源程序）系统时钟的编程实现： 程序通过调用系统时间的函数类型java.util.Calendar 定义了一个时间变量System.DateTime currentTime = new System.DateTime()，并通过API函数Calendar currentTime = Calendar.getInstance()来获得当前的系统时间，并且按照固定格式输出。在时钟时间的实现中，首先实现了对JPanel类的继承类clock的定义，并且对其paintComponent(Graphics g)函数进行重载。代码
