    The main API for dates, times, instants, and durations.

    The main API for dates, times, instants, and durations.

    The classes defined here represent the principal date-time concepts, including instants, durations, dates, times, time-zones and periods. They are based on the ISO calendar system, which is the de facto world calendar following the proleptic Gregorian rules. All the classes are immutable and thread-safe.

    Each date time instance is composed of fields that are conveniently made available by the APIs. For lower level access to the fields refer to the org.threeten.bp.temporal package. Each class includes support for printing and parsing all manner of dates and times. Refer to the org.threeten.bp.format package for customization options.

    The org.threeten.bp.chrono package contains the calendar neutral API. This is intended for use by applications that need to use localized calendars. It is recommended that applications use the ISO-8601 dates and time classes from this package across system boundaries, such as to the database or across the network. The calendar neutral API should be reserved for interactions with users.

    Dates and Times

    org.threeten.bp.Instant is essentially a numeric timestamp. The current Instant can be retrieved from a org.threeten.bp.Clock. This is useful for logging and persistence of a point in time and has in the past been associated with storing the result from java.lang.System#currentTimeMillis().

    org.threeten.bp.LocalDate stores a date without a time. This stores a date like '2010-12-03' and could be used to store a birthday.

    org.threeten.bp.LocalTime stores a time without a date. This stores a time like '11:30' and could be used to store an opening or closing time.

    org.threeten.bp.LocalDateTime stores a date and time. This stores a date-time like '2010-12-03T11:30'.

    org.threeten.bp.OffsetTime stores a time and offset from UTC without a date. This stores a date like '11:30+01:00'. The ZoneOffset is of the form '+01:00'.

    org.threeten.bp.OffsetDateTime stores a date and time and offset from UTC. This stores a date-time like '2010-12-03T11:30+01:00'. This is sometimes found in XML messages and other forms of persistence, but contains less information than a full time-zone.

    org.threeten.bp.ZonedDateTime stores a date and time with a time-zone. This is useful if you want to perform accurate calculations of dates and times taking into account the org.threeten.bp.ZoneId, such as 'Europe/Paris'. Where possible, it is recommended to use a simpler class. The widespread use of time-zones tends to add considerable complexity to an application.

    Duration and Period

    Beyond dates and times, the API also allows the storage of period and durations of time. A org.threeten.bp.Duration is a simple measure of time along the time-line in nanoseconds. A org.threeten.bp.Period expresses an amount of time in units meaningful to humans, such as years or hours.

    Additional value types

    org.threeten.bp.Year stores a year on its own. This stores a single year in isolation, such as '2010'.

    org.threeten.bp.YearMonth stores a year and month without a day or time. This stores a year and month, such as '2010-12' and could be used for a credit card expiry.

    org.threeten.bp.MonthDay stores a month and day without a year or time. This stores a month and day-of-month, such as '--12-03' and could be used to store an annual event like a birthday without storing the year.

    org.threeten.bp.Month stores a month on its own. This stores a single month-of-year in isolation, such as 'DECEMBER'.

    org.threeten.bp.DayOfWeek stores a day-of-week on its own. This stores a single day-of-week in isolation, such as 'TUESDAY'.

    Provides classes to print and parse dates and times.

    Printing and parsing is based around the DateTimeFormatter class. That class contains common formatters and factory methods. The DateTimeFormatterBuilder class is available for advanced and complex use cases.

    Localization occurs by calling withLocale(Locale) on the formatter. Further customization is possible using DecimalStyle.

DateTimeBuilder

final class DateTimeBuilder extends TemporalAccessor with Cloneable

Builder that can holds date and time fields and related date and time objects.

The builder is used to hold onto different elements of date and time. It is designed as two separate maps:

  • from TemporalField to long value, where the value may be outside the valid range for the field
  • from Class to TemporalAccessor, holding larger scale objects like LocalDateTime.
Specification for implementors

This class is mutable and not thread-safe. It should only be used from a single thread.

Creates an empty instance of the builder.

  10. def get(field: TemporalField): Int

    Gets the value of the specified field as an int.

    Gets the value of the specified field as an int.

    This queries the date-time for the value for the specified field. The returned value will always be within the valid range of values for the field. If the date-time cannot return the value, because the field is unsupported or for some other reason, an exception will be thrown.

    Specification for implementors

    Implementations must check and handle all fields defined in ChronoField. If the field is supported and has an int range, then the value of the field must be returned. If unsupported, then a DateTimeException must be thrown.

    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument.

    Implementations must not alter either this object.

    Checks if the specified field is supported.

    This checks if the date-time can be queried for the specified field. If false, then calling the range and get methods will throw an exception.

    Specification for implementors

    Implementations must check and handle all fields defined in ChronoField. If the field is supported, then true is returned, otherwise false

    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.isSupportedBy(TemporalAccessor) passing this as the argument.

    Implementations must not alter this object.

  19. def query[R](query: TemporalQuery[R]): R

    Queries this date-time.

    Queries this date-time.

    This queries this date-time using the specified query strategy object.

    Queries are a key tool for extracting information from date-times. They exists to externalize the process of querying, permitting different approaches, as per the strategy design pattern. Examples might be a query that checks if the date is the day before February 29th in a leap year, or calculates the number of days to your next birthday.

    The most common query implementations are method references, such as LocalDate::from and ZoneId::from. Further implementations are on TemporalQueries. Queries may also be defined by applications.

    Specification for implementors

    Implementations of this method must behave as follows: 

    public <R> R query(TemporalQuery<R> type) {
// only include an if statement if the implementation can return it
if (query == TemporalQueries.zoneId())  return // the ZoneId
if (query == TemporalQueries.chronology())  return // the Chrono
if (query == TemporalQueries.precision())  return // the precision
// call default method
return super.query(query);
}

  20. def range(field: TemporalField): ValueRange

    Gets the range of valid values for the specified field.

    Gets the range of valid values for the specified field.

    All fields can be expressed as a long integer. This method returns an object that describes the valid range for that value. The value of this temporal object is used to enhance the accuracy of the returned range. If the date-time cannot return the range, because the field is unsupported or for some other reason, an exception will be thrown.

    Note that the result only describes the minimum and maximum valid values and it is important not to read too much into them. For example, there could be values within the range that are invalid for the field.

    Specification for implementors

    Implementations must check and handle all fields defined in ChronoField. If the field is supported, then the range of the field must be returned. If unsupported, then a DateTimeException must be thrown.

    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.rangeRefinedBy(TemporalAccessorl) passing this as the argument.

    Implementations must not alter either this object.

    field

    Resolves the builder, evaluating the date and time.

    This examines the contents of the builder and resolves it to produce the best available date and time, throwing an exception if a problem occurs. Calling this method changes the state of the builder.
