Method

Date	add(Date date, int calendarField, int amount) Adds to a date returning a new object.
Date	addDays(Date date, int amount) Adds a number of days to a date returning a new object.
Date	addHours(Date date, int amount) Adds a number of hours to a date returning a new object.

Date	ceiling(Date date, int field) Ceil this date, leaving the field specified as the most significant field. For example, if you had the datetime of 28 Mar 2002 13:45:01.231, if you passed with HOUR, it would return 28 Mar 2002 14:00:00.000.
Calendar	ceiling(Calendar date, int field) Ceil this date, leaving the field specified as the most significant field. For example, if you had the datetime of 28 Mar 2002 13:45:01.231, if you passed with HOUR, it would return 28 Mar 2002 13:00:00.000.
Date	ceiling(Object date, int field) Ceil this date, leaving the field specified as the most significant field. For example, if you had the datetime of 28 Mar 2002 13:45:01.231, if you passed with HOUR, it would return 28 Mar 2002 13:00:00.000.
long	getFragmentInDays(Date date, int fragment) Returns the number of days within the fragment.
long	getFragmentInDays(Calendar calendar, int fragment) Returns the number of days within the fragment.
long	getFragmentInHours(Date date, int fragment) Returns the number of hours within the fragment.
long	getFragmentInHours(Calendar calendar, int fragment) Returns the number of hours within the fragment.
long	getFragmentInMinutes(Date date, int fragment) Returns the number of minutes within the fragment.
long	getFragmentInMinutes(Calendar calendar, int fragment) Returns the number of minutes within the fragment.
boolean	isSameDay(Date date1, Date date2) Checks if two date objects are on the same day ignoring time. 28 Mar 2002 13:45 and 28 Mar 2002 06:01 would return true.
boolean	isSameDay(Calendar cal1, Calendar cal2) Checks if two calendar objects are on the same day ignoring time. 28 Mar 2002 13:45 and 28 Mar 2002 06:01 would return true.
boolean	isSameInstant(Date date1, Date date2) Checks if two date objects represent the same instant in time. This method compares the long millisecond time of the two objects.
boolean	isSameInstant(Calendar cal1, Calendar cal2) Checks if two calendar objects represent the same instant in time. This method compares the long millisecond time of the two objects.
Iterator	iterator(Date focus, int rangeStyle) This constructs an `Iterator` over each day in a date range defined by a focus date and range style. For instance, passing Thursday, July 4, 2002 and a `RANGE_MONTH_SUNDAY` will return an `Iterator` that starts with Sunday, June 30, 2002 and ends with Saturday, August 3, 2002, returning a Calendar instance for each intermediate day. This method provides an iterator that returns Calendar objects.
Iterator	iterator(Calendar focus, int rangeStyle) This constructs an `Iterator` over each day in a date range defined by a focus date and range style. For instance, passing Thursday, July 4, 2002 and a `RANGE_MONTH_SUNDAY` will return an `Iterator` that starts with Sunday, June 30, 2002 and ends with Saturday, August 3, 2002, returning a Calendar instance for each intermediate day. This method provides an iterator that returns Calendar objects.
Iterator	iterator(Object focus, int rangeStyle) This constructs an `Iterator` over each day in a date range defined by a focus date and range style. For instance, passing Thursday, July 4, 2002 and a `RANGE_MONTH_SUNDAY` will return an `Iterator` that starts with Sunday, June 30, 2002 and ends with Saturday, August 3, 2002, returning a Calendar instance for each intermediate day.
Date	parseDate(String str, String... parsePatterns) Parses a string representing a date by trying a variety of different parsers. The parse will try each parse pattern in turn.
Date	parseDateStrictly(String str, String... parsePatterns) Parses a string representing a date by trying a variety of different parsers. The parse will try each parse pattern in turn.
Date	round(Date date, int field) Round this date, leaving the field specified as the most significant field. For example, if you had the datetime of 28 Mar 2002 13:45:01.231, if this was passed with HOUR, it would return 28 Mar 2002 14:00:00.000.
