Java calculate days in year, or between two dates

Question

Is there a method in any native Java class to calculate how many days were/will be in a specific year? As in, was it a Leap year (366 days) or a normal year (365 days)?

Answer 1

The GregorianCalendar standar class has an isLeapyear() method. If all you've got is a year number (say, 2008), then construct a date using this constructor, and then check the isLeapYear() method afterwards.
