java实现简单聊天室单人版

本文实例为大家分享了java实现简单聊天室的具体代码，供大家参考，具体内容如下

先整理下思路：

1.创建一个通信服务端，传入端口号和相关的流后等待客户端连接，并初始化图形界面。
2.创建一个jframe，用于写出聊天的界面，这里界面名称由其他类传入。
3.把客户端创建的方法写进jframe（当然这里很粗糙的方法）
4.设置按钮的监听事件，发送消息和离线功能

首先创建一个服务端的类

import java.io.ioexception;
import java.net.serversocket;
import java.net.socket;
import com.jero.jframe.chatsocketjframe;
//创建服务端
public class chatserversocket{
  //构造初始化方法
  public chatserversocket(string name,int port) throws ioexception{
    //创建socket服务连接对象  
      serversocket serversocket = new serversocket(port);
    //等待客户端连接
      socket client = serversocket.accept();
    //初始化聊天界面  
      try {
        new chatsocketjframe(name,client);
      } catch (exception e) {
        // todo auto-generated catch block
        e.printstacktrace();
      }
    //关闭流
      serversocket.close();
  }
  public static void main(string[] args) throws exception{
    new chatserversocket("服务端",8001);//启动服务端，指定网名和端口
  }

}

package com.jero.jframe;
