( "Your Date of birth is : " + dateOfBirth) in the following example it will represent 14th January, nothing is hidden about it. Here dates are represented in the way you write it e.g. year started from 1900, months starting from zero, etc. The good thing about this method is that it has not repeated mistakes done in previous API e.g. In the first example, we have seen that creating today's date was very easy because of the static factory method now(), but you can also create a date from any arbitrary date by using another useful factory method called LocalDate.of(), this takes a year, month and date and return an equivalent LocalDate instance.

Compare this with the older way of getting the current date, month, and year in Java.Įxample 3 - How to get a particular date in Java 8 You can see how easy it is to get a year or month from a date in Java 8, just use the corresponding getter method, nothing to remember, very intuitive. ( "Year : %d Month : %d day : %d \t %n", year, month, day) By using these methods, you can get whatever property of date you want, no need to use a supporting class like : You can also see Java SE 8 for Really Impatient to learn about different ways to create LocalDate in Java 8.Įxample 2 - How to get a current day, month, and year in Java 8 The LocalDate class has a convenient method to extract the year, month, day of the month, and several other dates attributes from an instance of LocalDate class. It also prints the date in a nicely formatted way, unlike the previous Date class which prints data non-formatted. You can see that it has created today's date without any time information. So anytime if you just to represent date without time, use this class. This class is little different than because it only contains the date, no time part. Java 8 has a class called LocalDate which can be used to represent today's date. birthday, anniversary, next bill date, next premium date, your credit card expiry, etc.Įxample 1 - How to get today's date in Java 8
how to represent today's date using the Java 8 Date Time library then move forward to create a date with time and time zone, exploring how to do more real-world tasks like creating a reminder application how to find a number of days to important dates e.g. I have created a list of 20 task-based examples to learn this new gem from Java 8. Java 8's new date and time API is no different. In short, it's a task that motivates you to explore and learn new APIs. There are too many real requirements in a real project, which prompts a developer to explore and learn a new library. Someone asked me what is the best way to learn a new library? My answer was, use that library as if you are using it for your real project.
It's also very affordable and you can buy in just $10 on Udemy sales which happen every now and then. When you will run those samples, it will surely return the correct values.ītw, if you are not familiar with the new Date and Time API added on Java 8 then I suggest you first go through a comprehensive and up-to-date Java course like The Complete Java MasterClass on Udemy. By the way, just remember that I wrote this article almost a year ago when Java was about to launch, so you will find examples that have dates of the previous year. Parsing and Formatting of Dates are also revamped with the new DateTimeFormatter class. They are also coming with better time zone support with ZoneOffSet and ZoneId.

Hey are also based on the ISO Calendar system and unlike their predecessor, class in java.time packages are both immutable and thread-safe. It also follows good things from the Joda library about keeping human and machine interpretation of date-time separated. instants, duration, dates, times, timezones, and periods. One of the many good things about new Date and Time API is that now it defines principle date-time concepts e.g. It seems, Java has realized a need for better Date and time support, which is good for a community which already used to of Joda Date and Time API. Java's handling of Date, Calendar, and Time is long been criticized by the community, which is not helped by Java's decision of making mutable and SimpleDateFormat not thread-safe.
Along with lambda expressions, streams, and several minor goodies, Java 8 has also introduced brand new Date and Time API, and in this tutorial, we will learn how to use Java 8 Date Time API with simple how-to-do task examples.
