-/**\r
- * DateFormat is an abstract class for date/time formatting subclasses which\r
- * formats and parses dates or time in a language-independent manner.\r
- * The date/time formatting subclass, such as SimpleDateFormat, allows for\r
- * formatting (i.e., date -> text), parsing (text -> date), and\r
- * normalization. The date is represented as a <code>Date</code> object or\r
- * as the milliseconds since January 1, 1970, 00:00:00 GMT.\r
- *\r
- * <p>DateFormat provides many class methods for obtaining default date/time\r
- * formatters based on the default or a given locale and a number of formatting\r
- * styles. The formatting styles include FULL, LONG, MEDIUM, and SHORT. More\r
- * detail and examples of using these styles are provided in the method\r
- * descriptions.\r
- *\r
- * <p>DateFormat helps you to format and parse dates for any locale.\r
- * Your code can be completely independent of the locale conventions for\r
- * months, days of the week, or even the calendar format: lunar vs. solar.\r
- *\r
- * <p>To format a date for the current Locale, use one of the\r
- * static factory methods:\r
- * <pre>\r
- * myString = DateFormat.getDateInstance().format(myDate);\r
- * </pre>\r
- * <p>If you are formatting multiple numbers, it is\r
- * more efficient to get the format and use it multiple times so that\r
- * the system doesn't have to fetch the information about the local\r
- * language and country conventions multiple times.\r
- * <pre>\r
- * DateFormat df = DateFormat.getDateInstance();\r
- * for (int i = 0; i < a.length; ++i) {\r
- * output.println(df.format(myDate[i]) + "; ");\r
- * }\r
- * </pre>\r
- * <p>To format a number for a different Locale, specify it in the\r
- * call to getDateInstance().\r
- * <pre>\r
- * DateFormat df = DateFormat.getDateInstance(DateFormat.LONG, Locale.FRANCE);\r
- * </pre>\r
- * <p>You can use a DateFormat to parse also.\r
- * <pre>\r
- * myDate = df.parse(myString);\r
- * </pre>\r
- * <p>Use getDateInstance to get the normal date format for that country.\r
- * There are other static factory methods available.\r
- * Use getTimeInstance to get the time format for that country.\r
- * Use getDateTimeInstance to get a date and time format. You can pass in \r
- * different options to these factory methods to control the length of the\r
- * result; from SHORT to MEDIUM to LONG to FULL. The exact result depends\r
- * on the locale, but generally:\r
- * <ul><li>SHORT is completely numeric, such as 12.13.52 or 3:30pm\r
- * <li>MEDIUM is longer, such as Jan 12, 1952\r
- * <li>LONG is longer, such as January 12, 1952 or 3:30:32pm\r
- * <li>FULL is pretty completely specified, such as\r
- * Tuesday, April 12, 1952 AD or 3:30:42pm PST.\r
- * </ul>\r
- *\r
- * <p>You can also set the time zone on the format if you wish.\r
- * If you want even more control over the format or parsing,\r
- * (or want to give your users more control),\r
- * you can try casting the DateFormat you get from the factory methods\r
- * to a SimpleDateFormat. This will work for the majority\r
- * of countries; just remember to put it in a try block in case you\r
- * encounter an unusual one.\r
- *\r
- * <p>You can also use forms of the parse and format methods with\r
- * ParsePosition and FieldPosition to\r
- * allow you to\r
- * <ul><li>progressively parse through pieces of a string.\r
- * <li>align any particular field, or find out where it is for selection\r
- * on the screen.\r
- * </ul>\r
- *\r
- * <h4>Synchronization</h4>\r
- *\r
- * Date formats are not synchronized. It is recommended to create separate \r
- * format instances for each thread. If multiple threads access a format \r
- * concurrently, it must be synchronized externally. \r

+/**
+ * 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.
