In this article, we’re going to have a look at how to measure elapsed time in Java.While this may sound easy, there’re a few pitfalls that we must be aware of. We’ll explore standard Java classes and external packages that provide functionality to measure elapsed time. 2. Simple Mea...
In Java, you can use the following ways to measure elapsed time in Java. 1. System.nanoTime() This is the recommended solution to measure elapsed time in Java. ExecutionTime1.java package com.mkyong.time; import java.util.concurrent.TimeUnit; public class ExecutionTime1 { public static void...
public class MeasureTimeExampleJava { public static void main(String args[]) { //measuring elapsed time using System.nanoTime long startTime = System.nanoTime(); for(int i=0; i < 1000000; i++){ Object obj = new Object(); } long elapsedTime = System.nanoTime() - startTime; System...

public static longnanoTime() Returns the current value of the most precise available system timer, in nanoseconds. This method can only be used to measure elapsed time and is not related to any other notion of system or wall-clock time. The value returned represents nanoseconds since some fixe...
This method can only be used to measure elapsed time and is not related to any other notion of system or wall-clock time. The value returned represents nanoseconds since some fixed but arbitrary time (perhaps in the future, so values may be negative). This method provides nanosecond precision...

The information written to this file is similar to the output of -verbose:gc with the time elapsed since the first GC event preceding each logged event. The -Xloggc option overrides -verbose:gc if both are given with the same java command. Example: -Xloggc:garbage-collection.log -Xmax...
So we employ the definition of the duration of a second to measure the passing of time. We can notably use seconds (and its fractions) to measure durations: how long it takes us to go shopping, how long it takes to boil an egg. A duration is the answer to the question "how long"...
