/** | |
* 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 <code>Date</code> object or | |
* as the milliseconds since January 1, 1970, 00:00:00 GMT. | |
* | |
* <p>DateFormat provides many class methods for obtaining default date/time | |
* formatters based on the default or a given loacle 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. | |
* | |
* <p>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. | |
* | |
* <p>To format a date for the current Locale, use one of the | |
* static factory methods: | |
* <pre> | |
* myString = DateFormat.getDateInstance().format(myDate); | |
* </pre> | |
* <p>If you are formatting multiple numbers, 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. | |
* <pre> | |
* DateFormat df = DateFormat.getDateInstance(); | |
* for (int i = 0; i < a.length; ++i) { | |
* output.println(df.format(myDate[i]) + "; "); | |
* } | |
* </pre> | |
* <p>To format a number for a different Locale, specify it in the | |
* call to getDateInstance(). | |
* <pre> | |
* DateFormat df = DateFormat.getDateInstance(DateFormat.LONG, Locale.FRANCE); | |
* </pre> | |
* <p>You can use a DateFormat to parse also. | |
* <pre> | |
* myDate = df.parse(myString); | |
* </pre> | |
* <p>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: | |
* <ul><li>SHORT is completely numeric, such as 12.13.52 or 3:30pm | |
* <li>MEDIUM is longer, such as Jan 12, 1952 | |
* <li>LONG is longer, such as January 12, 1952 or 3:30:32pm | |
* <li>FULL is pretty completely specified, such as | |
* Tuesday, April 12, 1952 AD or 3:30:42pm PST. | |
* </ul> | |
* | |
* <p>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. | |
* | |
* <p>You can also use forms of the parse and format methods with | |
* ParsePosition and FieldPosition to | |
* allow you to | |
* <ul><li>progressively parse through pieces of a string. | |
* <li>align any particular field, or find out where it is for selection | |
* on the screen. | |
* </ul> | |
* | |
* <h4>Synchronization</h4> | |
* | |
* 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. | |
