Known Direct Subclasses

SimpleDateFormat

is a concrete class for formatting and parsing dates in a locale-sensitive manner.

DateFormat is an abstract class for date/time formatting subclasses which formats and parses dates or time in a language-independent manner. The date/time formatting subclass, such as SimpleDateFormat, allows for formatting (i.e., date → text), parsing (text → date), and normalization. The date is represented as a Date object or as the milliseconds since January 1, 1970, 00:00:00 GMT.

DateFormat provides many class methods for obtaining default date/time formatters based on the default or a given locale and a number of formatting styles. The formatting styles include FULL, LONG, MEDIUM, and SHORT. More detail and examples of using these styles are provided in the method descriptions.

DateFormat helps you to format and parse dates for any locale. Your code can be completely independent of the locale conventions for months, days of the week, or even the calendar format: lunar vs. solar.

To format a date for the current Locale, use one of the static factory methods:

<code>myString = DateFormat.getDateInstance().format(myDate);
  </code>

If you are formatting multiple dates, it is more efficient to get the format and use it multiple times so that the system doesn't have to fetch the information about the local language and country conventions multiple times.

<code>DateFormat df = DateFormat.getDateInstance();
  for (int i = 0; i &lt; myDate.length; ++i) {
      output.println(df.format(myDate[i]) + "; ");
  }
  </code>

To format a date for a different Locale, specify it in the call to getDateInstance().

<code>DateFormat df = DateFormat.getDateInstance(DateFormat.LONG, Locale.FRANCE);
  </code>

You can use a DateFormat to parse also.

<code>myDate = df.parse(myString);
  </code>

Use getDateInstance to get the normal date format for that country. There are other static factory methods available. Use getTimeInstance to get the time format for that country. Use getDateTimeInstance to get a date and time format. You can pass in different options to these factory methods to control the length of the result; from SHORT to MEDIUM to LONG to FULL. The exact result depends on the locale, but generally:

SHORT is completely numeric, such as 12.13.52 or 3:30pm
MEDIUM is longer, such as Jan 12, 1952
LONG is longer, such as January 12, 1952 or 3:30:32pm
FULL is pretty completely specified, such as Tuesday, April 12, 1952 AD or 3:30:42pm PST.

You can also set the time zone on the format if you wish. If you want even more control over the format or parsing, (or want to give your users more control), you can try casting the DateFormat you get from the factory methods to a SimpleDateFormat. This will work for the majority of countries; just remember to put it in a try block in case you encounter an unusual one.

You can also use forms of the parse and format methods with ParsePosition and FieldPosition to allow you to

progressively parse through pieces of a string.
align any particular field, or find out where it is for selection on the screen.

Synchronization

Date formats are not synchronized. It is recommended to create separate format instances for each thread. If multiple threads access a format concurrently, it must be synchronized externally.

Inherited functions

From class Format

String!

format(obj: Any!)

Formats an object to produce a string. This is equivalent to format(obj, new StringBuffer(), new FieldPosition(0)).toString();

AttributedCharacterIterator!

formatToCharacterIterator(obj: Any!)

Formats an Object producing an AttributedCharacterIterator. You can use the returned AttributedCharacterIterator to build the resulting String, as well as to determine information about the resulting String.

Each attribute key of the AttributedCharacterIterator will be of type Field. It is up to each Format implementation to define what the legal values are for each attribute in the AttributedCharacterIterator, but typically the attribute key is also used as the attribute value.

The default implementation creates an AttributedCharacterIterator with no attributes. Subclasses that support fields should override this and create an AttributedCharacterIterator with meaningful attributes.

Any!

parseObject(source: String!)

Parses text from the beginning of the given string to produce an object. The method may not use the entire text of the given string.

Properties
Calendar	`calendar` The `Calendar` instance used for calculating the date-time fields and the instant of time.
NumberFormat	`numberFormat` The number formatter that `DateFormat` uses to format numbers in dates and times.

equals

Added in API level 1

open fun equals(other: Any?): Boolean

Overrides equals

Parameters
`obj`	the reference object with which to compare.

Return
`Boolean`	`true` if this object is the same as the obj argument; `false` otherwise.

format

Added in API level 1

    toAppendTo: StringBuffer, 
    fieldPosition: FieldPosition
): StringBuffer

Formats the given Object into a date-time string. The formatted string is appended to the given StringBuffer.

Parameters
`obj`	Any: Must be a `Date` or a `Number` representing a millisecond offset from the Epoch.
`toAppendTo`	StringBuffer: The string buffer for the returning date-time string.
`pos`	A `FieldPosition` identifying a field in the formatted text

Return
`Boolean`	`true` if the `calendar` is lenient; `false` otherwise.

See Also

java.util.Calendar#isLenient()

parse

Added in API level 1

open fun parse(source: String): Date?

Parses text from the beginning of the given string to produce a date. The method may not use the entire text of the given string.

See the parse(java.lang.String,java.text.ParsePosition) method for more information on date parsing.

WARNING: Don't use this method to deserialize a date. The underlying localized date/time format and parsing behaviors can change across Android versions as common usage in the locale changes. Consider using long type for storing a timestamp or java.time.format.DateTimeFormatter#ISO_INSTANT for deserializing the ISO-8601 instant format.

Parameters
`source`	String: A `String` whose beginning should be parsed.

Return
`Date?`	A `Date` parsed from the string.

Exceptions
`java.text.ParseException`	if the beginning of the specified string cannot be parsed.

parse

Added in API level 1

abstract fun parse(
    source: String, 
    pos: ParsePosition
): Date?

Parse a date/time string according to the given parse position. For example, a time text "07/10/96 4:5 PM, PDT" will be parsed into a Date that is equivalent to Date(837039900000L).

By default, parsing is lenient: If the input is not in the form used by this object's format method but can still be parsed as a date, then the parse succeeds. Clients may insist on strict adherence to the format by calling setLenient(false).

This parsing operation uses the calendar to produce a Date. As a result, the calendar's date-time fields and the TimeZone value may have been overwritten, depending on subclass implementations. Any TimeZone value that has previously been set by a call to setTimeZone may need to be restored for further operations.

Parameters
`source`	String: The date/time string to be parsed
`pos`	ParsePosition: On input, the position at which to start parsing; on output, the position at which parsing terminated, or the start position if the parse failed.

Return
`Date?`	A `Date`, or `null` if the input could not be parsed

parseObject

Added in API level 1

open fun parseObject(
    source: String, 
    pos: ParsePosition
): Any?

Parses text from a string to produce a Date.

The method attempts to parse text starting at the index given by pos. If parsing succeeds, then the index of pos is updated to the index after the last character used (parsing does not necessarily use all characters up to the end of the string), and the parsed date is returned. The updated pos can be used to indicate the starting point for the next call to this method. If an error occurs, then the index of pos is not changed, the error index of pos is set to the index of the character where the error occurred, and null is returned.

See the parse(java.lang.String,java.text.ParsePosition) method for more information on date parsing.

Parameters
`source`	String: A `String`, part of which should be parsed.
`pos`	ParsePosition: A `ParsePosition` object with index and error index information as described above.

Return
`Any?`	A `Date` parsed from the string. In case of error, returns null.

Exceptions
`java.lang.NullPointerException`	if `source` or `pos` is null.

setCalendar

Added in API level 1

open fun setCalendar(newCalendar: Calendar): Unit

Set the calendar to be used by this date format. Initially, the default calendar for the specified or default locale is used.

Any TimeZone and leniency values that have previously been set are overwritten by newCalendar's values.

Parameters
`newCalendar`	Calendar: the new `Calendar` to be used by the date format

setLenient

Added in API level 1

open fun setLenient(lenient: Boolean): Unit

Specify whether or not date/time parsing is to be lenient. With lenient parsing, the parser may use heuristics to interpret inputs that do not precisely match this object's format. With strict parsing, inputs must match this object's format.

This method is equivalent to the following call.

<code>getCalendar().setLenient(lenient)
  </code>

This leniency value is overwritten by a call to setCalendar().

Parameters
`lenient`	Boolean: when `true`, parsing is lenient

See Also

java.util.Calendar#setLenient(boolean)

setNumberFormat

Added in API level 1

open fun setNumberFormat(newNumberFormat: NumberFormat): Unit

Allows you to set the number formatter.

Parameters
`newNumberFormat`	NumberFormat: the given new NumberFormat.

setTimeZone

Added in API level 1

open fun setTimeZone(zone: TimeZone): Unit

Sets the time zone for the calendar of this DateFormat object. This method is equivalent to the following call.

<code>getCalendar().setTimeZone(zone)
  </code>

The TimeZone set by this method is overwritten by a setCalendar call.

The TimeZone set by this method may be overwritten as a result of a call to the parse method.

Parameters
`zone`	TimeZone: the given new time zone.

Properties

calendar
