To add hours or minutes to the Java Instant Class object we can make use of the plus methods from the Instant class.
Example:import java.time.Instant;
import java.time.temporal.ChronoUnit;
public class JavaInstantClassExample {
public static void main(String[] args) {
int hoursToAdd = 4;
int minutesToAdd = 30;
Instant currentTimeStampInUTC = Instant.now();
System.out.println("Current Time: "+currentTimeStampInUTC);
System.out.println("Adding 4 hours and 30 minutes to current time");
Instant laterTime = currentTimeStampInUTC.plus(hoursToAdd,ChronoUnit.HOURS)
.plus(minutesToAdd,ChronoUnit.MINUTES);
System.out.println("Later Time: "+laterTime);
}
}
Output:
Current Time: 2022-05-13T18:37:55.991272Z
Adding 4 hours and 30 minutes to current time
Later Time: 2022-05-13T23:07:55.991272Z
