Find speed of local application using java

If you have a local application and you would like to know how much time its taking to load, you can try this simple code snipped to find the load time and get insights on how much time its taking to load.

Code:
==================================================================
import java.net.*;
import java.io.*;
public class TimerTest
{
    public static final Double NANO_TO_MILLIS = 1000000.0;
    public static void main(String[] args) throws MalformedURLException, IOException
    {
        int i =0;
        while(i<5){
        // start timer
        long nanoStart = System.nanoTime();
        long milliStart = System.currentTimeMillis();
        // do work to be timed
        doWork();
        // stop timer
        long nanoEnd = System.nanoTime();
        long milliEnd = System.currentTimeMillis();
        // report response times
        long nanoTime = nanoEnd - nanoStart;
        long milliTime = milliEnd - milliStart;
        reportResponseTimes(nanoTime, milliTime);
        i++;
        }
    }
    private static void reportResponseTimes(long nanoTime, long milliTime)
    {
        // convert nanoseconds to milliseconds and display both times with three digits of precision (microsecond)
        String nanoFormatted = String.format("%,.3f", nanoTime / NANO_TO_MILLIS);
        String milliFormatted = String.format("%,.3f", milliTime / 1.0 );
        //System.out.println("Milliseconds using nanoTime(): " + nanoFormatted);
        System.out.println("Milliseconds using currentTimeMillis: " + milliFormatted);
    }
    private static void doWork() throws MalformedURLException, IOException
    {
        URL url = new URL("http://google.com");
        URLConnection conn = url.openConnection();
        BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        System.out.println("Checking "+url.toString());
       
        while (in.readLine() != null) {
            //System.out.println(in.readLine());
        }
        in.close();
    }
}
