It allows for formatting 0N/A * (date -> text), parsing (text -> date), and normalization. 0N/A * <code>SimpleDateFormat</code> allows you to start by choosing 0N/A * any user-defined patterns for date-time formatting. However, you 0N/A * are encouraged to create a date-time formatter with either 0N/A * <code>getTimeInstance</code>, <code>getDateInstance</code>, or 0N/A * <code>getDateTimeInstance</code> in <code>DateFormat</code>. Each 0N/A * of these class methods can return a date/time formatter initialized 0N/A * with a default format pattern. You may modify the format pattern 0N/A * using the <code>applyPattern</code> methods as desired. 0N/A * For more information on using these methods, see 0N/A * {@link DateFormat}. 0N/A * <h4>Date and Time Patterns</h4> 0N/A * Date and time formats are specified by <em>date and time pattern</em> 0N/A * Within date and time pattern strings, unquoted letters from 0N/A * <code>'A'</code> to <code>'Z'</code> and from <code>'a'</code> to 0N/A * <code>'z'</code> are interpreted as pattern letters representing the 0N/A * components of a date or time string. 0N/A * Text can be quoted using single quotes (<code>'</code>) to avoid 0N/A * <code>"''"</code> represents a single quote. 0N/A * All other characters are not interpreted; they're simply copied into the 0N/A * output string during formatting or matched against the input string 0N/A * The following pattern letters are defined (all other characters from 0N/A * <code>'A'</code> to <code>'Z'</code> and from <code>'a'</code> to 0N/A * <code>'z'</code> are reserved): 0N/A * <table border=0 cellspacing=3 cellpadding=0 summary="Chart shows pattern letters, date/time component, presentation, and examples."> 0N/A * <tr bgcolor="#ccccff"> 0N/A * <th align=left>Letter 0N/A * <th align=left>Date or Time Component 0N/A * <th align=left>Presentation 0N/A * <th align=left>Examples 0N/A * <td><code>G</code> 0N/A * <td>Era designator 0N/A * <td><a href="#text">Text</a> 0N/A * <td><code>AD</code> 0N/A * <tr bgcolor="#eeeeff"> 0N/A * <td><code>y</code> 0N/A * <td><a href="#year">Year</a> 0N/A * <td><code>1996</code>;

otherwise it is interpreted as a 0N/A * <a href="#number">number</a>. 0N/A * <li>For parsing, if the number of pattern letters is more than 2, 0N/A * the year is interpreted literally, regardless of the number of 0N/A * digits. So using the pattern "MM/dd/yyyy", "01/11/12" parses to 0N/A * <li>For parsing with the abbreviated year pattern ("y" or "yy"), 0N/A * <code>SimpleDateFormat</code> must interpret the abbreviated year 0N/A * relative to some century. It does this by adjusting dates to be 0N/A * within 80 years before and 20 years after the time the <code>SimpleDateFormat</code> 0N/A * instance is created. For example, using a pattern of "MM/dd/yy" and a 0N/A * <code>SimpleDateFormat</code> instance created on Jan 1, 1997, the string 0N/A * "01/11/12" would be interpreted as Jan 11, 2012 while the string "05/04/64" 0N/A * would be interpreted as May 4, 1964. 0N/A * During parsing, only strings consisting of exactly two digits, as defined by 0N/A * {@link Character#isDigit(char)}, will be parsed into the default century. 0N/A * Any other numeric string, such as a one digit string, a three or more digit 0N/A * string, or a two digit string that isn't all digits (for example, "-1"), is 0N/A * interpreted literally. So "01/02/3" or "01/02/003" are parsed, using the 0N/A * same pattern, as Jan 2, 3 AD. Likewise, "01/02/-3" is parsed as Jan 2, 4 BC. 0N/A * Otherwise, calendar system specific forms are applied. 0N/A * For both formatting and parsing, if the number of pattern 0N/A * letters is 4 or more, a calendar specific {@linkplain 0N/A * Calendar#LONG long form} is used. Otherwise, a calendar 0N/A * specific {@linkplain Calendar#SHORT short or abbreviated form} 2702N/A * If week year {@code 'Y'} is specified and the {@linkplain 2702N/A * #getCalendar() calendar} doesn't support any <a 2702N/A * years</a>, the calendar year ({@code 'y'}) is used instead. The 2702N/A * support of week years can be tested with a call to {@link 2702N/A * DateFormat#getCalendar() getCalendar()}.{@link 2702N/A * java.util.Calendar#isWeekDateSupported() 2702N/A * isWeekDateSupported()}.<br><br></li> 0N/A * <li><strong><a name="month">Month:</a></strong> 0N/A * If the number of pattern letters is 3 or more, the month is 0N/A * interpreted as <a href="#text">text</a>; otherwise, 2702N/A * it is interpreted as a <a href="#number">number</a>.<br><br></li> 0N/A * <li><strong><a name="timezone">General time zone:</a></strong> 0N/A * Time zones are interpreted as <a href="#text">text</a> if they have 0N/A * names.
