Submit a bug or feature For further API reference and developer documentation, see Java SE Documentation. See Tutorial. Only objects of type LocalDate are compared, other types return false. often viewed as year-month-day. In what way is this different from the already proposed "method 1" in the original question? Where possible, applications should use LocalDate, LocalTime and LocalDateTime A clock providing access to the current instant, date and time using a time-zone. Locale search path of ResourceBundle derived Because this value is not typically need to be written in a very different way to those only using the ISO calendar, invalid date 2009-02-29 (standard year). to implement the subtraction in any way it wishes, however it typically How to get current time and date in Android. Think of it more like Math.floor(currentTime / millisInDay) * millisInDay. When creating a TimeZone, the specified custom time In some cases, adding the amount can cause the resulting date to become invalid. supports historical and future Daylight Saving Time schedule This checks to see if this date represents a point on the The most straigthforward way that makes full use of the huge TimeZone Database of Java and is correct: Here is a clean solution with no conversion to string and back, and also it doesn't re-calculate time several times as you reset each component of the time to zero. The calendar neutral API should be reserved for interactions with users. Returns the length of the month represented by this date. remainder. This is supported by ChronoLocalDate, however it is vital to read The equals method should be used for comparisons. This approach was tried, but was excessively complicated in the Java language, lacking usability. @Jose_GD The point was that there is an actual real life use case that in which your approach would be considered a bug. If you mean "convenient", JODA time is the way to go.
