 82                 
 83             } catch (Exception e) {
 84                 // TODO: handle exception
 85                 e.printStackTrace();
 86             }
 87         }
 88     }
 89     
 90     public void getSocket(){
 91         jTextArea.append("正在与劲爆聊天室进行连接..."+"\n");
 92         try {
 93             socket=new Socket("127.0.0.1",PortNumber.PORT.getNumber());
 94             jTextArea.append("劲爆聊天开始..."+"\n");
 95             bufferedReader=new BufferedReader(new InputStreamReader(socket.getInputStream()));
 96             printWriter=new PrintWriter(socket.getOutputStream(),true);
 97             new Thread(this).start();
 98         } catch (Exception e) {
 99             // TODO: handle exception
100             e.printStackTrace();
101         }
102     }
103     
104 }

考虑到多客户端，此处用到了多线程。Socket确实有意思....

非常感叹T公司如果把一个IM软件，做到亿级用户量，如何解决并发，如何解决Server的及时回应，如何完成数据存储...

想不出来了...
