Most idiomatic way to print a time difference in Java?

Question

I\'m familiar with printing time difference in milliseconds:

 long time = System.currentTimeMillis();
 //do something that takes some time...
 long completed         


        

Answer 1

If you actually want to see a millisecond difference, I don't think there's a shorter, simpler way.

If you need a more powerful (but certainly not simpler) way to collect performance statistics, there is Perf4J.
