In this case we need to specify a time-of-day to go along with our date-only value, to be combined for a java.util.Date object. First moment of the day likely makes sense. Let java.time determine the time of that first moment as it is not always 00:00:00.0. We also need to specify a time zone, as the date varies by time zone.
The isSupported method of TemporalAccessor can be used in most situations. // Example birthdays ordered from the best known to the completely unknown TemporalAccessor [] birthdays = { LocalDate.of (1955, Month.MARCH, 22), YearMonth.of (1978, Month.MAY), Year.of (1969), IsoEra.CE }; for (TemporalAccessor birthday : birthdays) { String yearString
LocalDate.of( 2026 , 1 , 23 ) // Pass: ( year , month , day ) java.time. Some other Answers are correct in showing how to gather input from the user, but use the troublesome old date-time classes that are now legacy, supplanted by the java.time classes. LocalDate. For a date-only value without time-of-day and without time zone, use the

Let's say I have the current day, the next day, and the previous day. And I want to write a method that finds the first business day of the month by doing logical operations on them. For example, the first working day of November 2021 starts on the 4th, because the 3rd of the month has no working days due to holidays.

このクイックチュートリアルでは、JavaのDateからYear、Month、およびDayの整数値を抽出する方法について説明しました。 古い Date クラスと Calendar クラス、およびJava8の新しい日時ライブラリを使用してこれらの値を抽出する方法を示しました。
Date Input - Parsing Dates. If you have a valid date string, you can use the Date.parse() method to convert it to milliseconds.. Date.parse() returns the number of milliseconds between the date and January 1, 1970:
