阅读更多关于 Start and end date of a current month

It should be irrespective of the year and month. That is some month has 31 days or 30 days or 28 days. This should satisfy for a leap year too. Can you help me out with that? For example if I select month May in a list box I need starting date that is 1 and end date that is 31. There you go: public Pair<Date, Date> getDateRange() { Date begining, end; { Calendar calendar = getCalendarForNow(); calendar
