简单的 socket 编程

//以下为客户端主程序
package a;
import java.io.*;
import java.net.Socket;
import java.lang.*;
public class Client
{
private Socket con;//客户端连接socket
private OutputStream out;
private String sen;
private byte b[];
public Client()
{
  clientInit();
}

public void clientInit()
{
  try
  {
   con=new Socket("localhost",10015);
   con.setSoTimeout(1000);
   b=new byte[1024];
   OutputStream out=con.getOutputStream();
   sen="hello serve,以TCP方式发送数据！";
   b=sen.getBytes();
   out.write(b);
   out.flush();
   out.close();
   con.close();
  }
  catch(IOException ie)
  {
   ie.toString();
  }
}
public static void main(String args[])
{
  new Client();
}
