Getting the Local port

     

In this section you will learn that how a user can access the Local port. Here we are going to make it easier to understand the step be step process by the complete example on this topic. If we consider the example it will display the server's local port. For which we use a class ServerSocket which creates a server socket, bound to the specified port.

Here is The Complete Code :

LocalPort.java

import java.net.*;
import java.io.*;

public class LocalPort{
  public static void main(String[] args) {
  for (int i = 1; i <= 7000; i++) {
  try {
  ServerSocket server = new ServerSocket(i);
  }
  catch (IOException e) {
  System.out.println("There is a server on port " + i + ".");
  }
  }
  }
}

The output of the above example is as under in which the program display all the local port of the server.

Here is the Output of the Example :

C:\roseindia>javac LocalPort.java

C:\roseindia>java LocalPort
There is a server on port 135.
There is a server on port 139.
There is a server on port 445.
There is a server on port 1025.
There is a server on port 1027.
There is a server on port 1030.
There is a server on port 1032.
There is a server on port 1036.
There is a server on port 1038.
