史上最简单的socket

1. client

import java.io.IOException;
import java.io.OutputStream;
import java.net.Socket;
import java.net.UnknownHostException;

public class TcpClient2 {

/**
* @param args
* @throws IOException
* @throws UnknownHostException
*/
public static void main(String[] args) throws Exception {
// TODO Auto-generated method stub
Socket s = new Socket("192.168.1.120",9998);
OutputStream os = s.getOutputStream();
os.write("i will go".getBytes());
os.close();
s.close();
}

}

2. Server

import java.io.IOException;
import java.io.InputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class TcpServer2 {

/**
* @param args
* @throws Exception
*/
public static void main(String[] args) throws Exception {
// TODO Auto-generated method stub
ServerSocket ss = new ServerSocket(9998);
System.out.println(ss.getInetAddress());
Socket s = ss.accept();
InputStream is= s.getInputStream();
byte[] buf = new byte[1024];
int len = is.read(buf);
System.out.println(new String(buf,0,len));
}

}
