Method Summary

void

add(int field, int amount)

Adds the specified (signed) amount of time to the given calendar field, based on the calendar's rules.

protected void

Converts the time value (millisecond offset from the Epoch) to calendar field values.

protected void

Converts calendar field values to the time value (millisecond offset from the Epoch).

boolean

Compares this GregorianCalendar to the specified Object.

Obtains an instance of GregorianCalendar with the default locale from a ZonedDateTime object.

int

getActualMaximum(int field)

int

getActualMinimum(int field)

Returns "gregory" as the calendar type.

int

getGreatestMinimum(int field)

Returns the highest minimum value for the given calendar field of this GregorianCalendar instance.

Gets the Gregorian Calendar change date.

int

getLeastMaximum(int field)

Returns the lowest maximum value for the given calendar field of this GregorianCalendar instance.

int

getMaximum(int field)

Returns the maximum value for the given calendar field of this GregorianCalendar instance.

int

getMinimum(int field)

Returns the minimum value for the given calendar field of this GregorianCalendar instance.

int

Returns the number of weeks in the week year represented by this GregorianCalendar.

int

Returns the week year represented by this GregorianCalendar.

int

hashCode()

Generates the hash code for this GregorianCalendar object.

boolean

isLeapYear(int year)

Determines if the given year is a leap year.

final boolean

Returns true indicating this GregorianCalendar supports week dates.

void

roll(int field, boolean up)

Adds or subtracts (up/down) a single unit of time on the given time field without changing larger fields.

void

roll(int field, int amount)

Adds a signed amount to the specified calendar field without changing larger fields.

void

Sets the GregorianCalendar change date.

void

setWeekDate(int weekYear, int weekOfYear, int dayOfWeek)

Sets this GregorianCalendar to the date given by the date specifiers - weekYear, weekOfYear, and dayOfWeek.

Converts this object to a ZonedDateTime that represents the same point on the time-line as this GregorianCalendar.
