推荐答案

属性code>日历 类可以为您提供帮助。

The WEEK_OF_YEAR attribute of the Calendar class can be usefull for you.

创建一个新日期，该日期将是给定的月份。获取当天的一周，假设你有开始价值。

Create a new date that will be the first day of the given month. Get the week of the year for this day, let say you got start value.

创建一个新日期，将是给定月份的最后一天。获取当天的一周，所以现在你得到结束值。

Create a new date that will be the last day of the given month. Get the week of the year for this day, so now you got end value.

最后，创建一个简单的 int [] 将包含从开始到结束的值。

Finally, create a simple int[] that will contains values from start to end.
