Can you help to get the solution for this.

I want the solution like this.

localhost:8080 or some other ip server with port

You can try `System.out.println(System.getenv("HOSTNAME"));` — Elliott Frisch, Apr 02 '18 at 05:00

your can try this to get hostname

import java.net.InetAddress;
import java.net.UnknownHostException;

public class HostName {
public static void main(String a[]){
    try {
        InetAddress myHost = InetAddress.getLocalHost();
        System.out.println(myHost.getHostName());
    } catch (UnknownHostException ex) {
        ex.printStackTrace();
