Java 提供的多线程 功能 用多线程可完成多点对多点的聊天 主要有两个应用程序 分别为服务器程序和客户端程序 服务器应用程序主要用于消 息转发 以及向所有用户发送系统消息等 客户端应用程序主要用于客户聊天记录的显示 和信息输入 采用 Client Server C S 体系结构 即客户机 服务器体系结构 聊天服务器 专门用于监控用户状态和转发消息 客户端负责接收消息的用户序列和消息文本发送到服 务器 该聊天系统实现私聊 群聊 用户登陆 退出聊天系统等功能 本系统的主要功能有以下几个部分组成 本系统的主要功能有以下几个部分组成 服务器端模块 系统信息的输入 可以输入任何信息 功能 将系统信息广播至各个客户端 踢除用户 服务器可以选择性删除在线的用户 客户端模块 登陆服务器 列出当前在线用户信息 私聊和多人聊天的选择 发言 对输入的数据进行发送 离开状态 嘉兴学院 Java 综合实训报告 2
