| * {@icuenhanced java.text.DateFormat}.{@icu _usage_} |
| * |
| * <p>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 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. |
| * |
| * <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. |
