Some of the date and time classes also exhibit quite poor API design.For example, years in start at 1900, months start at 1, and days start at 0—not very intuitive.Some calendaring systems don’t even have a concept of a month or a week and calculations would need to be performed via the very generic field API.class covers the credit card start date and expiration date use cases and scenarios in which people have a date with no specified day.
There are also interfaces that correspond to core time point classes, but are parameterized by These classes are there purely for developers who are working on highly internationalized applications that need to take into account local calendaring systems, and they shouldn’t be used by developers without these requirements.
When constructing a value by its constituent fields, the factory is called Local Date Time time Point = Local Date Time.now( ); // The current date and time Local Date.of(2012, Month.
DECEMBER, 12); // from values Local Epoch Day(150); // middle of 1970 Local Time.of(17, 18); // the train I took home today Local Time.parse(""); // From a String // Set the value, returning a new object Local Date Time the Past = time Day Of Month( 10)Year(2010); /* You can use direct manipulation methods, or pass a value and field pair */ Local Date Time yet Another = the Weeks( 3).plus(3, Chrono Unit.
The project has been led jointly by the author of Joda-Time (Stephen Colebourne) and Oracle, under JSR 310, and will appear in the new Java SE 8 package Time zones, which disambiguate the contexts of different observers, are put to one side here; you should use these local classes when you don’t need that context.
A desktop Java FX application might be one of those times.
