Java8 calculate time difference milliseconds 2018-03-23 05:17
In this blog I will show you how to calculate two milliseconds in Java8. Java8 adds a new package java.time. It is easy to handle time by using the class in this package. The example code is here.
public class TimeDifferentClient {
public static void main(String[] args) throws InterruptedException {
Instant firstTime = Instant.ofEpochMilli(System.currentTimeMillis());
Thread.sleep(10 * 1000);
Instant secondTime = Instant.ofEpochMilli(System.currentTimeMillis());
Duration timeElapsed = Duration.between(firstTime, secondTime);
System.out.println("duration second:" + timeElapsed.getSeconds());
}
}
The example code needs 10 seconds to run. The output will be "duration second:10".
