The eras() method of java.time.chrono.MinguoChronology class is used to retrieve all the eras comes under this particular Minguo 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 Minguo chronology. Below are the examples to illustrate the eras() method: Example 1:Â
Java
// Java program to demonstrate// eras() methodÂ
import java.util.*;import java.io.*;import java.time.*;import java.time.chrono.*;Â
public class GFG {    public static void main(String[] argv)    {        try {            // creating and initializing            // MinguoDate Object            MinguoDate hidate                = MinguoDate.now();Â
            // getting MinguoChronology            // used in MinguoDate            MinguoChronology crono                = hidate.getChronology();Â
            // getting all MinguoEras present            // by using eras() method            List<Era> list = crono.eras();Â
            // display the result            System.out.println(                "MinguoEra is: "                + (list.iterator()).next());        }        catch (DateTimeException e) {            System.out.println(                "MinguoEra is invalid");            System.out.println(                "Exception thrown: " + e);        }    }} |
Output:
MinguoEra is: BEFORE_ROC
Example 2:Â
Java
// Java program to demonstrate// eras() methodÂ
import java.util.*;import java.io.*;import java.time.*;import java.time.chrono.*;Â
public class GFG {    public static void main(String[] argv)    {        try {            // creating and initializing            // MinguoDate Object            MinguoDate hidate                = MinguoDate.now();Â
            // getting MinguoChronology            // used in MinguoDate            MinguoChronology crono                = hidate.getChronology();Â
            // getting all MinguoEras present            // by using eras() method            List<Era> list = crono.eras();Â
            // getting list Iterator            Iterator iter = list.iterator();Â
            // display the result            System.out.println("List of MinguoEra : ");            for (int i = 0; i < 2; i++)                System.out.println(iter.next());        }        catch (DateTimeException e) {            System.out.println(                "MinguoEra is invalid");            System.out.println(                "Exception thrown: " + e);        }    }} |
Output:
List of MinguoEra : BEFORE_ROC ROC
