The java.time.temporal.TemporalAdjuster interface and the java.time.temporal.TemporalAdjusters class are both part of the Java Date-Time API, and they work together for adjusting temporal objects. TemporalAdjuster interface: This is a functional interface, which means it has only one abstract method, adjustInto(). This method is meant to adjust a temporal object, such as LocalDate, LocalDateTime, YearMonth, etc. The […]
java.time.Duration is another useful class in Java for dealing with time. It measures time in seconds and nanoseconds and is most suitable for smaller amounts of time, like “20 seconds” or “3 hours”, and not for larger units like “3 days” or “4 months”. Here’s a guide on how to use it: 1. Creating a […]

These constants include DAYS, HOURS, SECONDS, etc., that are often used to measure a quantity of time with respect to the specifics of a calendar system. Here’s an example of how you can use the ChronoUnit […]
In the Java Date-Time API, the plus and minus methods can be used to calculate and modify dates, times, date/times, and durations. Each temporal class (LocalDate, LocalTime, LocalDateTime, and Duration) includes these methods. Here’s a basic example using the LocalDate class: package org.kodejava.datetime; import java.time.LocalDate; public class PlusMinusExample { public static void main(String[] args) { […]
The atDate() method is a part of LocalTime class in the Java Date-Time API. This method combines this time with a date to create an instance of LocalDateTime. Here’s an example: package org.kodejava.datetime; import java.time.LocalDate; import java.time.LocalDateTime; import java.time.LocalTime; public class AtDateExample { public static void main(String[] args) { // Create a LocalTime instance LocalTime […]
