是否有任何DateTime库支持Java的一年中的每季度和每周的某周?

问题描述：

我目前正在将jodaTime DateTime 类用于我的Java专案.但是它不支持一年中的季度和一年中的一周.

I am currently using jodaTime DateTime class for my Java project. But it does not have support for quarter of the year and week of the year.

有没有可以用于此目的的Java库?

Is there any Java library which can be used for that purpose?

答

在Java 8中

In java 8 DateTimeFormatter supports quarters using q format and week of the year using w:

LocalDate date = LocalDate.now();
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("qqq w");
String text = date.format(formatter);

今天的日期(7月25日)，是每年的第三季度和第31周的结果:

Results in third quarter and 31st week of the year for todays date (July 25th):

"Q3 31"
