本文提供了Java中Server端与Client端通信的示例代码。Server端监听10000端口并接收Client消息，反馈确认信息。Client连接Server并发送用户输入的消息。

Server端程序:

import java.net.*; 

import java.io.*; 

public class Server 

{ 

private ServerSocket ss; 

private Socket socket; 

private BufferedReader in; 

private PrintWriter out; 

public Server() 

{ 

try 

{ 

ss=new ServerSocket(10000); 

while(true) 

{ 

socket = ss.accept(); 

String RemoteIP = socket.getInetAddress().getHostAddress(); 

String RemotePort = ":"+socket.getLocalPort(); 

System.out.println("A client come in!IP:"+RemoteIP+RemotePort); 

in = new BufferedReader(new 

InputStreamReader(socket.getInputStream())); 

String line = in.readLine(); 

System.out.println("Cleint send is :" + line); 

out = new PrintWriter(socket.getOutputStream(),true); 

out.println("Your Message Received!"); 

out.close(); 

in.close(); 

socket.close(); 

} 

}catch (IOException e) 

{ 

out.println("wrong"); 

} 

} 

public static void main(String[] args) 

{ 

new Server(); 

} 

};

Client端程序:

import java.io.*; 

import java.net.*; 



public class Client 

{ 

Socket socket; 

BufferedReader in; 

PrintWriter out; 

public Client() 

{ 

try 

{ 

System.out.println("Try to Connect to 127.0.0.1:10000"); 

socket = new Socket("127.0.0.1",10000); 

System.out.println("The Server Connected!"); 

System.out.println("Please enter some Character:"); 

BufferedReader line = new BufferedReader(new 

InputStreamReader(System.in)); 

out = new PrintWriter(socket.getOutputStream(),true); 

out.println(line.readLine()); 

in = new BufferedReader(new InputStreamReader(socket.getInputStream())); 

System.out.println(in.readLine()); 

out.close(); 

in.close(); 

socket.close(); 

}catch(IOException e) 

{ 

out.println("Wrong"); 

} 

} 

public static void main(String[] args) 

{ 

new Client(); 

} 

};
