public abstract class DateFormat extends Format
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:
myString = DateFormat.getDateInstance().format(myDate);
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.
DateFormat df = DateFormat.getDateInstance(); for (int i = 0; i < myDate.length; ++i) { output.println(df.format(myDate[i]) + "; "); }
To format a date for a different Locale, specify it in the call to getDateInstance()
.
DateFormat df = DateFormat.getDateInstance(DateFormat.LONG, Locale.FRANCE);
If the specified locale contains "ca" (calendar), "rg" (region override), and/or "tz" (timezone) Unicode extensions, the calendar, the country and/or the time zone for formatting are overridden. If both "ca" and "rg" are specified, the calendar from the "ca" extension supersedes the implicit one from the "rg" extension.
You can use a DateFormat to parse also.
myDate = df.parse(myString);
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 as12.13.52
or3:30pm
-
MEDIUM
is longer, such asJan 12, 1952
-
LONG
is longer, such asJanuary 12, 1952
or3:30:32pm
-
FULL
is pretty completely specified, such asTuesday, 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.
- Implementation Requirements:
- The
format(Date, StringBuffer, FieldPosition)
andparse(String, ParsePosition)
methods may throwNullPointerException
, if any of their parameter isnull
. The subclass may provide its own implementation and specification aboutNullPointerException
. - The
setCalendar(Calendar)
,setNumberFormat(NumberFormat)
andsetTimeZone(TimeZone)
methods do not throwNullPointerException
when their parameter isnull
, but any subsequent operations on the same instance may throwNullPointerException
. - The
getCalendar()
,getNumberFormat()
andgetTimeZone()
methods may returnnull
, if the respective values of this instance is set tonull
through the corresponding setter methods. For Example:getTimeZone()
may returnnull
, if theTimeZone
value of this instance is set assetTimeZone(null)
.

- keeps track on the position of the field within the returned string. For example, given a date-time text"1996.07.10 AD at 15:08:56 PDT"
, if the givenfieldPosition
isYEAR_FIELD
, the begin index and end index offieldPosition
will be set to 0 and 4, respectively. Notice that if the same date-time field appears more than once in a pattern, thefieldPosition
will be set for the first occurrence of that date-time field. For instance, formatting aDate
to the date-time string"1 PM PDT (Pacific Daylight Time)"
using the pattern"h a z (zzzz)"
and the alignment fieldTIMEZONE_FIELD
, the begin index and end index offieldPosition
will be set to 5 and 8, respectively, for the first occurrence of the timezone pattern character'z'
. - Returns:
- the string buffer passed in as
toAppendTo
, with formatted text appended. - Throws:
-
IllegalArgumentException
- if theFormat
cannot format the givenobj
. - See Also:

format
public abstract StringBuffer format(Date date, StringBuffer toAppendTo, FieldPosition fieldPosition)
Formats a Date
into a date-time string. The formatted string is appended to the given StringBuffer
.
- Parameters:
-
date
- a Date to be formatted into a date-time string. -
toAppendTo
- the string buffer for the returning date-time string. -

- keeps track on the position of the field within the returned string. For example, given a date-time text"1996.07.10 AD at 15:08:56 PDT"
, if the givenfieldPosition
isYEAR_FIELD
, the begin index and end index offieldPosition
will be set to 0 and 4, respectively. Notice that if the same date-time field appears more than once in a pattern, thefieldPosition
will be set for the first occurrence of that date-time field. For instance, formatting aDate
to the date-time string"1 PM PDT (Pacific Daylight Time)"
using the pattern"h a z (zzzz)"
and the alignment fieldTIMEZONE_FIELD
, the begin index and end index offieldPosition
will be set to 5 and 8, respectively, for the first occurrence of the timezone pattern character'z'

format
public final String format(Date date)
Formats a Date
into a date-time string.
- Parameters:
-
date
- the time value to be formatted into a date-time string. - Returns:
- the formatted date-time string.
parse
public Date parse(String source) throws ParseException
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(String, ParsePosition)
method for more information on date parsing.
- Parameters:
-
source
- AString
whose beginning should be parsed. - Returns:
- A
Date
parsed from the string. - Throws:
-
ParseException
- if the beginning of the specified string cannot be parsed.
parse
public abstract Date parse(String source, ParsePosition pos)
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
- The date/time string to be parsed -
pos
- 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. - Returns:
- A
Date
, ornull
if the input could not be parsed
parseObject
public Object parseObject(String source, ParsePosition pos)
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(String, ParsePosition)
method for more information on date parsing.
- Specified by:
-
parseObject
in classFormat
- Parameters:
-
source
- AString
, part of which should be parsed. -
pos
- AParsePosition
object with index and error index information as described above. - Returns:
