How do I do calendar arithmetic with java.util.Date?

Question

Currently I have a Date object representing a time. How would I add 5 minutes to this object?

Answer 1

With Java 8 there are new options. In fact Joda Time recommends moving to Java 8 Date and Time APIs as soon as possible. Here is an example of adding time from this link:

https://docs.oracle.com/javase/tutorial/datetime/iso/period.html

The following code adds 5 minutes to the current time:

LocalDateTime now = LocalDateTime.now();
now = now.plusMinutes(5);
System.out.println(now);
