  public enum IsoEra
extends Enum<IsoEra>
implements Era 
An era in the ISO calendar system. 
 The ISO-8601 standard does not define eras. A definition has therefore been created with two eras - 'Current era' (CE) for years on or after 0001-01-01 (ISO), and 'Before current era' (BCE) for years before that.

  Implementation Requirements: This is an immutable and thread-safe enum. Since: 1.8   Enum Constants   Enum Constant Description   BCE  The singleton instance for the era before the current one, 'Before Current Era', which has the numeric value 0.    CE  The singleton instance for the current era, 'Current Era', which has the numeric value 1.      Methods   Modifier and Type Method Description   int getValue()  Gets the numeric era int value.    static IsoEra of​(int isoEra)  Obtains an instance of IsoEra from an int value.    static IsoEra valueOf​(String name)  Returns the enum constant of this type with the specified name.    static IsoEra[] values()  Returns an array containing the constants of this enum type, in the order they are declared.

CE public static final IsoEra CE The singleton instance for the current era, 'Current Era', which has the numeric value 1.   Methods values public static IsoEra[] values() Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: for (IsoEra c : IsoEra.values())
    System.out.println(c);  Returns: an array containing the constants of this enum type, in the order they are declared  valueOf public static IsoEra valueOf(String name) Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)  Parameters: 
name - the name of the enum constant to be returned. Returns: the enum constant with the specified name Throws: 
IllegalArgumentException - if this enum type has no constant with the specified name 
NullPointerException - if the argument is null  of public static IsoEra of(int isoEra) 
Obtains an instance of IsoEra from an int value. 
 IsoEra is an enum representing the ISO eras of BCE/CE. This factory allows the enum to be obtained from the int value.
  Parameters: 
isoEra - the BCE/CE value to represent, from 0 (BCE) to 1 (CE) Returns: the era singleton, not null Throws: 
DateTimeException - if the value is invalid  getValue public int getValue() 
Gets the numeric era int value. 
 The era BCE has the value 0, while the era CE has the value 1.
  Specified by: 
getValue in interface Era
 Returns: the era value, from 0 (BCE) to 1 (CE)
