Problem Description:

How to create a socket at a specific port?

Solution:

Following example shows how to sing Socket constructor of Socket class.And also get Socket details using getLocalPort() getLocalAddress , getInetAddress() & getPort() methods.

import java.io.IOException;
import java.net.InetAddress;
import java.net.Socket;
import java.net.SocketException;
import java.net.UnknownHostException;

public class Main {
   public static void main(String[] args) {
      try {
         InetAddress addr = 
         InetAddress.getByName("74.125.67.100");
         Socket theSocket = new Socket(addr, 80);
         System.out.println("Connected to " 
         + theSocket.getInetAddress()
         + " on port " + theSocket.getPort() + " from port "
         + theSocket.getLocalPort() + " of " 
         + theSocket.getLocalAddress());
      } 
      catch (UnknownHostException e) {
         System.err.println("I can't find " + e  );
      }
      catch (SocketException e) {
         System.err.println("Could not connect to " +e );
      }
      catch (IOException e) {
         System.err.println(e);
      }
   }
}

Result:

The above code sample will produce the following result.

Connected to /74.125.67.100 on port 80 from port 
2857 of /192.168.1.4
