/**
|
|
59 |
* <code>DateFormatSymbols</code> is a public class for encapsulating
|
|
60 |
* localizable date-time formatting data, such as the names of the
|
|
61 |
* months, the names of the days of the week, and the time zone data.
|
|
62 |
* <code>DateFormat</code> and <code>SimpleDateFormat</code> both use
|
|
63 |
* <code>DateFormatSymbols</code> to encapsulate this information.
|
|
64 |
*
|
|
65 |
* <p>
|
|
66 |
* Typically you shouldn't use <code>DateFormatSymbols</code> directly.
|
|
67 |
* Rather, you are encouraged to create a date-time formatter with the
|
|
68 |
* <code>DateFormat</code> class's factory methods: <code>getTimeInstance</code>,
|
|
69 |
* <code>getDateInstance</code>, or <code>getDateTimeInstance</code>.
|
|
70 |
* These methods automatically create a <code>DateFormatSymbols</code> for
|
|
71 |
* the formatter so that you don't have to. After the
|
|
72 |
* formatter is created, you may modify its format pattern using the
|
|
73 |
* <code>setPattern</code> method. For more information about
|
|
74 |
* creating formatters using <code>DateFormat</code>'s factory methods,
|
|
75 |
* see {@link DateFormat}.
|
|
76 |
*
|
|
77 |
* <p>
|
|
78 |
* If you decide to create a date-time formatter with a specific
|
|
79 |
* format pattern for a specific locale, you can do so with:
|
|
80 |
* <blockquote>
|
|
81 |
* <pre>
|
|
82 |
* new SimpleDateFormat(aPattern, DateFormatSymbols.getInstance(aLocale)).
|
|
83 |
* </pre>
|
|
84 |
* </blockquote>
|
|
85 |
*
|
|
86 |
* <p>
|
|
87 |
* <code>DateFormatSymbols</code> objects are cloneable. When you obtain
|
|
88 |
* a <code>DateFormatSymbols</code> object, feel free to modify the
|
|
89 |
* date-time formatting data. For instance, you can replace the localized
|
|
90 |
* date-time format pattern characters with the ones that you feel easy
|
|
91 |
* to remember. Or you can change the representative cities
|
|
92 |
* to your favorite ones.
|
|
93 |
*
|
|
94 |
* <p>
|
|
95 |
* New <code>DateFormatSymbols</code> subclasses may be added to support
|
|
96 |
* <code>SimpleDateFormat</code> for date-time formatting for additional locales.
