LocalDateTime implements the {@link ReadablePartial} interface.To do this, certain methods focus on key fields Year, MonthOfYear, DayOfYear and MillisOfDay. However, all fields may in fact be queried.
Internally, LocalDateTime uses a single millisecond-based value to represent the local datetime. This value is only used internally and is not exposed to applications.
Calculations on LocalDateTime are performed using a {@link Chronology}. This chronology will be set internally to be in the UTC time zone for all calculations.
Each individual field can be queried in two ways:
getHourOfDay() hourOfDay().get() LocalDateTime is thread-safe and immutable, provided that the Chronology is as well. All standard Chronology classes supplied are thread-safe and immutable. @author Stephen Colebourne @since 1.3
{@code LocalDateTime} is an immutable date-time object that represents a date-time,often viewed as year-month-day-hour-minute-second. Other date and time fields, such as day-of-year, day-of-week and week-of-year, can also be accessed. Time is represented to nanosecond precision. For example, the value "2nd October 2007 at 13:45.30.123456789" can be stored in a {@code LocalDateTime}.
This class does not store or represent a time-zone. Instead, it is a description of the date, as used for birthdays, combined with the local time as seen on a wall clock. It cannot represent an instant on the time-line without additional information such as an offset or time-zone.
The ISO-8601 calendar system is the modern civil calendar system used today in most of the world. It is equivalent to the proleptic Gregorian calendar system, in which today's rules for leap years are applied for all time. For most applications written today, the ISO-8601 rules are entirely suitable. However, any application that makes use of historical dates, and requires them to be accurate will find the ISO-8601 approach unsuitable.
This is a value-based class; use of identity-sensitive operations (including reference equality ( {@code ==}), identity hash code, or synchronization) on instances of {@code LocalDateTime} may have unpredictable results and should be avoided.The {@code equals} method should be used for comparisons. @implSpec This class is immutable and thread-safe. @since 1.8
LocalDateTime is an immutable calendrical that represents a date-time, often viewed as year-month-day-hour-minute-second. This object can also access other fields such as day of year, day of week and week of year.
This class stores all date and time fields, to a precision of nanoseconds. It does not store or represent a time zone. Thus, for example, the value "2nd October 2007 at 13:45.30.123456789" can be stored in an LocalDateTime.
