socket 长连接怎么写

Question

请问这个是不是一个短连接例子  我想做成一个长连接的例子请问怎么做  谢谢
import java.io.*;
import java.net.*;
public class EchoServer1 extends Thread {
   Socket socket1;
   public EchoServer1( Socket s) {
      socket1=s;
      start();
   }
   public void run() {
      try {
       BufferedReader in=new BufferedReader(new InputStreamReader(socket1.getInputStream()));
       //InputStream in=socket1.getInputStream();
         PrintWriter out =new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket1.getOutputStream())), true);
         char[] sa=new char[500];
         String stra=null;
String str=null;
int aaa=0;
aaa=in.read(sa);
str = new String(sa,0,30).trim();
//stra = new String(straa.getBytes("iso8859-1"),"gb2312");
            //str=in.readLine();
            System.out.println("Server receives: " +str);
            out.write("Server returns back "+str);

out.flush();
in.close();
out.close();
      }
        
   catch (IOException e) {
      System.err.println("IO Exception");
   }
   finally {
      try {
         socket1.close();
      }
      catch (IOException e) {
         System.err.println("Socket not closed");
      }
   }
}static final int PORT = 8082;
public static void main(String[] args) throws IOException {
   ServerSocket s = new ServerSocket(PORT);
      System.out.println("Server Started");
      try {
         while(true) {
            Socket socket1 = s.accept();
            try {
               new EchoServer1(socket1);
            }
            catch(Exception e) {
                socket1.close();
            }
         }
      }
      finally {
         s.close();
      }
   }
}

你所说的长连接是不是在两台不同电脑的连接？
如果是参考如下：
server端》
ServerSocket ss=new ServerSocket(port);//port通信端口
Socket soc=ss.accept();
OutputStream os=soc.getOutputStream();
.....
client端》
Socket socket=new Socket(serverInetAddress,port);//serverInetAddress为服务器地址
InputStream is=socket.getInputStream();
....
