There are two options available to get an instance of GregorianCalendar: Calendar.getInstance()and using one of the constructors. Using the static factory method Calendar.getInstance() isn’t a recommended approach as it will return an instance subjective to the default locale.

With Java 8, new methods have been introduced to GregorianCalendar. The from() method gets an instance of GregorianCalendarwith the default locale from a ZonedDateTime object. Using getCalendarType() we can get the type of the calendar instance.The available calendar types are ‘gregory’, ‘buddhist’ and ‘japanese’. We can use this, for example, to m...
The calendar fields can be modified using the methods add(), roll() and set(). The add() method allows us to add time to the calendar in a specified unitbased on the calendar’s internal ruleset: We can also use the add()method to subtract time from the calendar object: Execution of the add()method forces an immediate re-computation of the calendar’...
JAXB allows mapping Java classes to XML representations. The javax.xml.datatype.XMLGregorianCalendar type can help in mapping the basic XSD schema types such as xsd:date, xsd:time and xsd:dateTime. Let’s have a look at an example to convert from GregorianCalendar type into the XMLGregorianCalendartype: Once the calendar object has been translated i...
We can use the Calendar classes’ compareTo()method to compare dates. The result will be positive if the base date is in the future and negative if the base data is in the past of the date we compare it to:
We can convert GregorianCalendar into a specific format by using a combination of ZonedDateTime and DateTimeFormatterto get the desired output:
GregorianCalendarprovides several get methods which can be used to fetch different calendar attributes. Let’s look at the different options we have: 1. getActualMaximum(int field) – returns the maximum value for the specified calendar field taking into consideration the current time values. The following example will return value 30 for the DAY_OF_...
A Calendar object can produce all the calendar field values needed to implement the date-time formatting for a particular language and calendar style (for example, Japanese-Gregorian, Japanese-Traditional).
