java实验3技术实验报告模板

1、Java 技术实验实验（三）：年月日学院计算机与信息学院专业班级计算机科学与技术 13-3 班学号2013211700实验名称基于 GUI 的网络通信程序设计指导教师教师评语教师签名：年月日一、实验目的掌握 Java 中 GUI 程序的编写，包括事件 机制。掌握 Java 的网络通信编程，ServerSocket，Socket 类的使用。 3掌握 Java 中多线程的编程，Thread 类，Runnable 接口的使用。 4掌握用面 象的方法分析和解决复杂问题。二、实验原理三、使用硬件、环境PC 计算机一台，配置为 CPU 为 1.5G，内存为 4GB，硬盘为 128G，安装 Windows7

2、 操作系统。另外，使用 JCreator，JDK1.6.0 等四、实验过程、步骤及原始(算法、原程序、，分析等)1 安装 Jdk1.5.0 集成环境,安装成功后，配置 path，classpath 路径，让用户在任何目录下均可用到 Java 的系统资源。2 源代码：服务器：import import import importimportjava.io.*; .*; javax.swing.*; java.awt.event.*;java.awt.*;publicclass ServerUI extendsJFrameJTextArea mainArea; JTextField sendAre
