导读：服务器，使用ServerSocket监听指定的端口，端口可以随意指定（由于1024以下的端口通常属于保留端口，客户端，使用Socket对网络上某一个服务器的某一个端口发出连接请求，一旦连接成功，打开会话；会话完成后， java.io.* 建立连接打开输出流封装输出流

服务器，使用ServerSocket监听指定的端口，端口可以随意指定（由于1024以下的端口通常属于保留端口，

客户端，使用Socket对网络上某一个服务器的某一个端口发出连接请求，一旦连接成功，打开会话；会话完成后，

java.io.* 建立连接打开输出流封装输出流向客户端发送数据关闭打开的输出流关闭打开的socket对象 ServerSocket s = ServerSocket(8888 ( Socket socket = OutputStream os = DataOutputStream dos = .getInetAddress()获取远程ip地址，s

.getPort()远程客户端的断后好 dos.writeUTF("你好,客户端地址信息: " + + "t客户端通信端口号: " + dos.writeUTF("i'm a server,my name is hongten！" } } }

java.io.* Socket s1 = Socket("127.0.0.1",8888 InputStream is = DataInputStream dis = } }

你好,客户端地址信息: /127.0.0.1 客户端通信端口号: 2800 i'm a server,my name is hongten！

???? 2.实现单线程的聊天室

java.io.* ServerSocket s = ServerSocket(8888 Socket s1 = OutputStream os = DataOutputStream dos = InputStream is = DataInputStream dis = InputStreamReader isr = BufferedReader br = ( info = System.out.println("对方说: " + (info.equals("bye" info = (info.equals("bye" } System.out.println("网络连接异常，程序退出!" } }

java.io.* Socket s1 = Socket("localhost",8888 OutputStream os = DataOutputStream dos = InputStream is = DataInputStream dis = InputStreamReader isr = BufferedReader br = ( info = (info.equals("bye" info = System.out.println("对方说: " + (info.equals("bye" } }

对方说: 13 代售点

对方说: 你今?? 13 对方说: 代售??

info =

info = dis.readUTF();

???? 3.实现多线程的聊天室

  
  java.io.*  java.net.* 
 
       
                               
             ServerSocket s =  ServerSocket(8888             
             Socket s1 = 
                           
             
             OutputStream os =             
             DataOutputStream dos =              
             InputStream is =             
             DataInputStream dis =              
                                   }      
 
  MyServerReader       
              .dis =  
                              (                                  
                 info =                 
                 System.out.println("对方说: " +                  (info.equals("bye"                     System.out.println("对方下线，程序退出!"                     System.exit(0           }      
 
  MyServerWriter       
              .dos =  
               
         InputStreamReader isr =          
         BufferedReader br =                         (                 info =                   (info.equals("bye"                     System.out.println("自己下线，程序退出!"                     System.exit(0           }     }

java.io.* java.net.* Socket s1 = Socket("127.0.0.1",8888 InputStream is = DataInputStream dis = OutputStream os = DataOutputStream dos = } MyClientReader .dis = ( info = System.out.println("对方说: " + (info.equals("bye" System.out.println("对方下线，程序退出!" System.exit(0 } MyClientWriter .dos = InputStreamReader isr = BufferedReader br = ( info = (info.equals("bye" System.out.println("自己下线，程序退出!" System.exit(0 } }

对方说: 我是服务器端，这说我说的第一句话，hehe

对方说: 这是客户?? 我是服务器端，这说我说的第一句话，hehe
