Calculating time difference in Milliseconds

Question

I am making a call to a method by passing ipAddress and it will return back the location of ipAddress like Country, City, etc etc. So I was trying to see how much time it is

Answer 1

From Java 8 onward you can try the following:

import java.time.*;
import java.time.temporal.ChronoUnit;

Instant start_time = Instant.now();
// Your code
Instant stop_time = Instant.now();

System.out.println(Duration.between(start_time, stop_time).toMillis());

//or

System.out.println(ChronoUnit.MILLIS.between(start_time, stop_time));
