Class Year
- Comparable, MonthConstants, Serializable, TimePeriod
Represents a year in the range 1900 to 9999. This class is immutable, which
is a requirement for all
RegularTimePeriod subclasses.
Year()- Creates a new
Year, based on the current system date/time.
|
Year(Date time)- Creates a new
Year, based on a particular instant in time,
using the default time zone.
|
Year(Date time, TimeZone zone)- Constructs a year, based on a particular instant in time and a time zone.
|
Year(int year)- Creates a time period representing a single year.
|
int | compareTo(Object o1)- Returns an integer indicating the order of this
Year object
relative to the specified object:
negative == before, zero == same, positive == after.
|
boolean | equals(Object object)- Tests the equality of this
Year object to an arbitrary
object.
|
long | getFirstMillisecond(Calendar calendar)- Returns the first millisecond of the year, evaluated using the supplied
calendar (which determines the time zone).
|
long | getLastMillisecond(Calendar calendar)- Returns the last millisecond of the year, evaluated using the supplied
calendar (which determines the time zone).
|
long | getSerialIndex()- Returns a serial index number for the year.
|
int | getYear()- Returns the year.
|
int | hashCode()- Returns a hash code for this object instance.
|
RegularTimePeriod | next()- Returns the year following this one.
|
static Year | parseYear(String s)- Parses the string argument as a year.
|
RegularTimePeriod | previous()- Returns the year preceding this one.
|
String | toString()- Returns a string representing the year..

Year
public Year()
Creates a new Year, based on the current system date/time.
Year
public Year(Date time)
Creates a new Year, based on a particular instant in time,
using the default time zone.
time - the time (null not permitted).
Year
public Year(Date time,
TimeZone zone) Constructs a year, based on a particular instant in time and a time zone.
time - the time.zone - the time zone.
Year
public Year(int year)
Creates a time period representing a single year.
compareTo
public int compareTo(Object o1)
Returns an integer indicating the order of this Year object
relative to the specified object:
negative == before, zero == same, positive == after.
o1 - the object to compare.
- negative == before, zero == same, positive == after.
equals
public boolean equals(Object object)
Tests the equality of this Year object to an arbitrary
object. Returns true if the target is a Year
instance representing the same year as this object. In all other cases,
returns false.
true if the year of this and the object are the
same.
getYear
public int getYear()
Returns the year.
hashCode
public int hashCode()
Returns a hash code for this object instance. The approach described by
Joshua Bloch in "Effective Java" has been used here:

parseYear
public static Year parseYear(String s)
Parses the string argument as a year.
The string format is YYYY.
s - a string representing the year.
null if the string is not parseable, the year
otherwise.
