Timing code

This one is quick.

Java

Here is how you do it :

import java.lang.Thread;  

public class Main {
  public static void main(String[] args)  throws Exception {
        
    long startTime = System.nanoTime();
    Thread.sleep(3000);
    long endTime = System.nanoTime();
    //divide by 1000000 to get milliseconds.
    int duration = (int) ((endTime - startTime) / (1000000 * 1000));  

    System.out.println("it took: " + duration + " secs");
  }
}

-----

it took: 3 secs

Prolog

?- numlist(1, 100, L).
L = [1, 2, 3, 4, 5, 6, 7, 8, 9|...].

?- time(numlist(1, 100, L)).
% 105 inferences, 0.000 CPU in 0.000 seconds (94% CPU, 1126344 Lips)
L = [1, 2, 3, 4, 5, 6, 7, 8, 9|...].
