Parameter: This method does not accept any argument as a parameter.
Return Value: This method returns all the eras comes under this particular Japanese 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 // JapaneseDate Object JapaneseDate hidate = JapaneseDate.now(); // getting JapaneseChronology // used in JapaneseDate JapaneseChronology crono = hidate.getChronology(); // getting all JapaneseEras present // by using eras() method List<Era> list = crono.eras(); // display the result System.out.println( "JapaneseEra is: " + (list.iterator()).next()); } catch (DateTimeException e) { System.out.println( "JapaneseEra is invalid"); System.out.println( "Exception thrown: " + e); } } } |
JapaneseEra is: Meiji
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 // JapaneseDate Object JapaneseDate hidate = JapaneseDate.now(); // getting JapaneseChronology // used in JapaneseDate JapaneseChronology crono = hidate.getChronology(); // getting all JapaneseEras 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 : "); for ( int i = 0 ; i < 4 ; i++) System.out.println(iter.next()); } catch (DateTimeException e) { System.out.println( "JapaneseEra is invalid"); System.out.println( "Exception thrown: " + e); } } } |
