What will be the output of the following Java program?

import java.lang.System;
class Output
{
     public static void main(String args[])
     {
         long start, end;   
         start = System.currentTimeMillis();
         for (int i = 0; i < 10000000; i++);
         end = System.currentTimeMillis();
         System.out.print(end - start);
     }
}
