Is there a stopwatch in Java?

Question

Is there a stopwatch in Java? In google, I find only the code of stopwatches that do not work.

Answer 1

You can use org.apache.commons.lang.time.StopWatch. If you are looking for more precision, use System.nanoTime().

Spring also provides a class in the spring-core module

org.springframework.util.StopWatch

You can use it like this:

StopWatch stopWatch = new StopWatch();

stopWatch.start();

// Do something

stopWatch.stop();

System.out.println(stopWatch.getTotalTimeMillis());
