IsoChronology eras() method in Java with Example
The eras() method of java.time.chrono.IsoChronology class is used to retrieve all the eras comes under this particular Iso chronology.
Syntax:
public List eras()
Parameter: This method does not accept any argument as a parameter.
Return Value: This method returns all the eras comes under this particular Iso chronology.
Below are the examples to illustrate the eras() method:
Example 1:
Java
// Java program to demonstrate // eras() method import java.util.*; import java.io.*; import java.time.*; import java.time.chrono.*; public class GFG { public static void main(String[] argv) { try { // creating and initializing // LocalDate Object LocalDate hidate = LocalDate.now(); // getting IsoChronology // used in LocalDate IsoChronology crono = hidate.getChronology(); // getting all IsoEras present // by using eras() method List<Era> list = crono.eras(); // display the result System.out.println("IsoEra is: " + (list.iterator()).next()); } catch (DateTimeException e) { System.out.println("IsoEra is invalid"); System.out.println("Exception thrown: " + e); } } } |
Output:
IsoEra is: BCE
Example 2:
Java
// Java program to demonstrate // eras() method import java.util.*; import java.io.*; import java.time.*; import java.time.chrono.*; public class GFG { public static void main(String[] argv) { try { // creating and initializing // LocalDate Object LocalDate hidate = LocalDate.now(); // getting IsoChronology // used in LocalDate IsoChronology crono = hidate.getChronology(); // getting all IsoEras present // by using eras() method List<Era> list = crono.eras(); // getting list Iterator Iterator iter = list.iterator(); // display the result System.out.println("List of IsoEra : " + "\n" + iter.next() + "\n" + iter.next()); } catch (DateTimeException e) { System.out.println("IsoEra is invalid"); System.out.println("Exception thrown: " + e); } } } |
Output:
List of IsoEra : BCE CE
