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();
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()

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();
