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 < a.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);
 
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 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.

protected DateFormat()
Create a new date format.

Method Detail

format
public final StringBuffer format(Object obj,
                                 StringBuffer toAppendTo,
                                 FieldPosition fieldPosition)
Overrides Format. Formats a time object into a time string. Examples of time objects are a time value expressed in milliseconds and a Date object.

Specified by:
format in class Format

Parameters:
obj - must be a Number or a Date.
toAppendTo - the string buffer for the returning time string.
fieldPosition - keeps track of the position of the field within the returned string. On input: an alignment field, if desired. On output: the offsets of the alignment field. For example, given a time text "1996.07.10 AD at 15:08:56 PDT", if the given fieldPosition is DateFormat.YEAR_FIELD, the begin index and end index of fieldPosition will be set to 0 and 4, respectively. Notice that if the same time field appears more than once in a pattern, the fieldPosition will be set for the first occurrence of that time field. For instance, formatting a Date to the time string "1 PM PDT (Pacific Daylight Time)" using the pattern "h a z (zzzz)" and the alignment field DateFormat.TIMEZONE_FIELD, the begin index and end index of fieldPosition will be set to 5 and 8, respectively, for the first occurrence of the timezone pattern character 'z'.
Returns:
the formatted time string.

format
public abstract StringBuffer format(Date date,
                                    StringBuffer toAppendTo,
                                    FieldPosition fieldPosition)
Formats a Date into a date/time string.

Parameters:
date - a Date to be formatted into a date/time string.
toAppendTo - the string buffer for the returning date/time string.
fieldPosition - keeps track of the position of the field within the returned string. On input: an alignment field, if desired. On output: the offsets of the alignment field. For example, given a time text "1996.07.10 AD at 15:08:56 PDT", if the given fieldPosition is DateFormat.YEAR_FIELD, the begin index and end index of fieldPosition will be set to 0 and 4, respectively. Notice that if the same time field appears more than once in a pattern, the fieldPosition will be set for the first occurrence of that time field. For instance, formatting a Date to the time string "1 PM PDT (Pacific Daylight Time)" using the pattern "h a z (zzzz)" and the alignment field DateFormat.TIMEZONE_FIELD, the begin index and end index of fieldPosition will be set to 5 and 8, respectively, for the first occurrence of the timezone pattern character 'z'.
Returns:
the formatted date/time string.

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 time string.
Returns:
the formatted 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 - A String 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(837039928046).
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).

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, or null if the input could not be parsed
See Also:
setLenient(boolean)

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 class Format

Parameters:
source - A String, part of which should be parsed.
pos - A ParsePosition object with index and error index information as described above.
Returns:
A Date parsed from the string. In case of error, returns null.
Throws:
NullPointerException - if pos is null.
