JAVA中SCOKET通信2

 

Server端程序: 
package test; 
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();       //查看链接的主机IP
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: 
package test; 
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(); 
} 
};
