I have seen recently code of GregorianCalendar in which I saw the function of isLeapYear:

That was as follows:




Now I really cann't relate why there is a reason to check whether is it divisible by 100 and 400 after checking divisible by 4.... I mean to say that if a number is divisible by 4 then it will be automatically divisible by 100 and 400.....

Then what is the use.......


COuld anybody explain this one...

I also don't understand why the code is checking that passed parameter is whether greater then 1582 or not.....

So 8 is divisible by 100?

As to 1582, the Gregorian Calendar did not exist before (and there is a 10-day leap in that year).
