计算机科学与技术13-3班实验

1、Java 技术实验实验（ 三 ）： 四号机房2014 年 12 月 15 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学号2013211698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、实验原理继承 JFrame 类创建两个类服务器，使之界面画。并且利用事件器对界面的操作做出相应反应

2、。其中通过实现 Runnable 线程类来同步其中的。三、使用硬件、环境PC 计算机一台，配置为 CPU 为 1.5G，内存为 512M，硬盘为 40G，安装 WindowsXP 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)源程序：1.接受器： package business;import java.io.EOFException; import java.io.IOException; import java.io.ObjectInputStream;import java.io.ObjectOutputStream; im
