How do I time a method's execution in Java?

Anonymous User 1947 07-Aug-2015

How do I get a method's execution time? Is there a Timer utility class for things like timing how long a task takes, etc?

Most of the searches on Google return results for timers that schedule threads and tasks, which is not what I want.

There is always the old-fashioned way:

long startTime = System.nanoTime();
methodToTime();
long endTime = System.nanoTime();
long duration = (endTime - startTime);
