问题 How can you make LocalDate to return Date in a specific format ? Ex . LocalDate ld = LocalDate.now(); The above statement will return date like 2018-11-24 but i want it to return like 24-11-2018 . ** Dont say use formatter because formatter will not return date , it will return String which is of no use for me . 回答1: Your question is contradictory, for example you want "24-11-2018" but also want "date" instead of "String" and overlook the fact that "24-11-2018" is a date in string form.

I'm very new to javascript so I can't find the right property to use instead of .toIsostring. What should I do ? function nextWeekdayDate(date, day_in_week) { var ret = new Date(date || new Date()); ret.setDate(ret.getDate() + (day_in_week - 1 - ret.getDay() + 7) % 7 + 1); return ret; } let nextFriday =

问题 I have an Instant coming from a source that should, according to the spec, be a LocalDate, but don't see any methods in LocalDate for the conversion. What is the best way to do this? 回答1: LocalDate.ofInstant(...); I believe was added in Java 9.
