Java计算一年中的天数 [英] Java calculate days in year

问题描述

在任何本机Java类中是否有一个方法来计算在特定年份中有多少天？如同，是闰年（366天）还是正常年份（365天）？

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)?

或者我需要自己写吗？

我计算两个日期之间的天数，例如，直到我的生日有多少天。我想考虑闰年的2月29日。

I'm calculating the number of days between two dates, for example, how many days left until my birthday. I want to take into account the February 29 of Leap year. I have it all done except that 29th.

推荐答案

GregorianCalendar standar类有一个 isLeapyear（）方法。如果你有一个年份（例如 2008 ），那么使用此构造函数，然后检查 isLeapYear（） 方法。

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.
