Java Date/Time Introduction 🎯

Welcome to our comprehensive guide on Java Date and Time! This tutorial is designed to help both beginners and intermediates understand the intricacies of working with dates and times in Java. Let's dive right in!

Understanding the Java Date and Time API 📝

In Java, the java.util.Date class has been replaced by the more modern java.time package. This package provides a rich set of classes to work with dates and times in a more intuitive and flexible way.

Key Classes in the java.time Package 💡

  • LocalDate: Represents a date (year, month, day) without time of day and time zone information.
  • LocalTime: Represents a time of day without date and time zone information.
  • LocalDateTime: Represents a date and time of day without time zone information.
  • ZonedDateTime: Represents a date and time of day along with the time zone.

Working with LocalDate 📝

Creating a LocalDate 💡

You can create a LocalDate instance using one of the several factory methods provided by the LocalDate class. Here's an example:

java
LocalDate today = LocalDate.now(); System.out.println(today);

Manipulating LocalDate 💡

You can manipulate a LocalDate using various methods like plusYears(), plusMonths(), plusDays(), and more.

java
LocalDate birthday = LocalDate.of(1990, 12, 31); LocalDate ageFromBirthday = LocalDate.now().minusYears(birthday.getYear()); System.out.println(ageFromBirthday);
