Why my program runs fast when I make a call to System.nanoTime() outside the System.out.println statement?
The second one creates a new StringBuilder and appends a String to it before taking the timings. The first one takes the timing before doing this extra work. The second one is equivalent to System.out.println(new StringBuilder().append("Time: ") .append(System.nanoTime() - t).toString()); or StringBuildler sb = new StringBuilder().append("Time: "); // included in timing l
