public final class ZoneOffset

  1. Object
  2. ZoneId
  3. ZoneOffset

ImplementsComparable<ZoneOffset>, TemporalAccessor

A fixed offset from UTC, between -18:00 and +18:00.

Fields

public static final ZoneOffset UTC
public static final ZoneOffset MIN
public static final ZoneOffset MAX

Methods

public static ZoneOffset of(String offsetId)Reads Z, +h, +hh, +hh:mm, +hhmm, +hh:mm:ss and +hhmmss, with - in place of + for a negative offset.
public static ZoneOffset ofHours(int hours)
public static ZoneOffset ofHoursMinutes(int hours, int minutes)
public static ZoneOffset ofHoursMinutesSeconds(int hours, int minutes, int seconds)The offset of hours, minutes and seconds, which must all have the same sign.
public static ZoneOffset ofTotalSeconds(int totalSeconds)
public static ZoneOffset from(TemporalAccessor temporal)The offset of temporal.
public int getTotalSeconds()
public int compareTo(ZoneOffset other)Larger offsets sort first, as in the JDK: an offset further east is an earlier moment for the same wall clock time.
public boolean equals(Object obj)Indicates whether some other object is “equal to” this one.
public int hashCode()Returns a hash code value for the object.

Method details

of

public static ZoneOffset of(String offsetId)
Reads Z, +h, +hh, +hh:mm, +hhmm, +hh:mm:ss and +hhmmss, with - in place of + for a negative offset.

ofHours

public static ZoneOffset ofHours(int hours)

ofHoursMinutes

public static ZoneOffset ofHoursMinutes(int hours, int minutes)

ofHoursMinutesSeconds

public static ZoneOffset ofHoursMinutesSeconds(int hours, int minutes, int seconds)
The offset of hours, minutes and seconds, which must all have the same sign.

ofTotalSeconds

public static ZoneOffset ofTotalSeconds(int totalSeconds)

from

public static ZoneOffset from(TemporalAccessor temporal)
The offset of temporal.

getTotalSeconds

public int getTotalSeconds()

compareTo

public int compareTo(ZoneOffset other)
Larger offsets sort first, as in the JDK: an offset further east is an earlier moment for the same wall clock time.

Parameters

other ZoneOffset
the object to compare to this instance.

Returns

a negative integer if this instance is less than another; a positive integer if this instance is greater than another; 0 if this instance has the same order as another.

Throws

ClassCastException
if another cannot be converted into something comparable to this instance.

equals

public boolean equals(Object obj)
Indicates whether some other object is “equal to” this one. The equals method implements an equivalence relation: It is reflexive: for any reference value x, x.equals(x) should return true. It is symmetric: for any reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true. It is transitive: for any reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true. It is consistent: for any reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the object is modified. For any non-null reference value x, x.equals(null) should return false. The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any reference values x and y, this method returns true if and only if x and y refer to the same object (x==y has the value true).

hashCode

public int hashCode()
Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable. The general contract of hashCode is: Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result. It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hashtables. As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)
