描述：基于tcp的Socket与ServerSocket的通信，客户端和服务端的聊天  
实现语言：java  
一：服务端的代码  
1：服务端的键盘录入代码

package chat;
    
    import java.io.BufferedReader;
    import java.io.BufferedWriter;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.io.OutputStreamWriter;
    import java.net.ServerSocket;
    import java.net.Socket;
    
    public class ServerWrit implements Runnable{ 
        Socket socket;
        public ServerWrit(Socket socket){
            this.socket=socket;
        }
        public void run(){
            try {
                BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
                BufferedWriter bw=new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
                String line="";
                while((line=br.readLine())!=null){
                    bw.write(line+"\r\n");
                    bw.flush();
                }
                socket.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }

2：读取客户端发来的信息：

package chat;
    
    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.net.ServerSocket;
    import java.net.Socket;
    
    public class ServerRead implements Runnable{ 
        Socket socket;
        public ServerRead(Socket socket){
            this.socket=socket;
        }
        public void run(){
            try {
                //获得输入
                BufferedReader read=new BufferedReader(new InputStreamReader(socket.getInputStream()));
    
                //进行读取
                String str="";
                while((str=read.readLine())!=null){
                    System.out.println("接受到客户端的话："+str);
                }
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }

3：服务端的启动代码：

package chat;
    
    import java.net.ServerSocket;
    import java.net.Socket;
    
    public class ServerTest { 
        public static void main(String[] args) throws Exception {
            ServerSocket servers=new ServerSocket(9090);
            Socket socket=servers.accept();
    
            new Thread(new ServerRead(socket)).start();
            new Thread(new ServerWrit(socket)).start();
            //servers.close(); 
        }
    
    }

二：客户端的实现：  
1：键盘录入线程

package chat;
    
    import java.io.BufferedReader;
    import java.io.BufferedWriter;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.io.OutputStreamWriter;
    import java.net.Socket;
    
    public class ClinckWrit implements Runnable{ 
        Socket socket;
        public ClinckWrit(Socket socket){
            this.socket=socket;
        }
        public void run(){
            try {
                //获得输出流
                BufferedWriter bw=new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
    
                //获得输入流
                BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
    
                String str="";
                while((str=br.readLine())!=null){
                    bw.write(str+"\r\n");
                    bw.flush();
                }
            }  catch (IOException e) {
                e.printStackTrace();
            }
    
        }
    
    }

2：读取客户端的消息线程

package chat;
    
    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.net.Socket;
    
    public class ClientRead implements Runnable{ 
        Socket socket;
        public ClientRead(Socket socket){
            this.socket=socket;
        }
        public void run(){
            try {
                BufferedReader br =new BufferedReader(new InputStreamReader(socket.getInputStream()));
                String str="";
                while((str=br.readLine())!=null){
                    System.out.println("服务端回应："+str);
                }
                socket.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    
    }

3：启动客户端的程序

package chat;
    
    import java.net.InetAddress;
    import java.net.Socket;
    
    public class ClientT { 
        public static void main(String[] args) throws Exception {
            Socket socket=new Socket(InetAddress.getLocalHost(),9090);
            new Thread(new ClinckWrit(socket)).start();
            new Thread(new ClientRead(socket)).start();
        }
    }

先启动服务端，然后再启动客户端，这样就可以愉快地聊天了  
稍作改动就可以做成群聊了
