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() methodimport 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); } }} |
Output:
JapaneseEra is: Meiji
Example 2:
Java
// Java program to demonstrate// eras() methodimport 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); } }} |
Output:
List of IsoEra : Meiji Taisho Showa Heisei
