Class Calendar

format

public String format(String pattern)

 

Shortcut for {@link SimpleDateFormat} to output a String representation of this calendar instance. This method respects the Calendar's assigned {@link TimeZone}, whereas calling cal.time.format('HH:mm:ss') would use the system timezone.

Note that Calendar equivalents of date.getDateString() and variants do not exist because those methods are Locale-dependent. Although a Calendar may be assigned a {@link Locale}, that information is lost and therefore cannot be used to control the default date/time formats provided by these methods. Instead, the system Locale would always be used. The alternative is to simply call {@link DateFormat#getDateInstance(int, Locale)} and pass the same Locale that was used for the Calendar.

Parameters:

pattern - format pattern.

Returns:

String representation of this calendar with the given format.

number of days
