Last Updated : 20 Jan, 2023

The eras() method of java.time.chrono.HijrahChronology class is used to retrieve all the eras comes under this particular hijrah 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 hijrah 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
            // HijrahDate Object
            HijrahDate hidate = HijrahDate.now();

            // getting HijrahChronology
            // used in HijrahDate
            HijrahChronology crono
                = hidate.getChronology();

            // getting all HijrahEras present
            // by using eras() method
            List<Era> list = crono.eras();

            // display the result
            System.out.println("HijrahEra is: "
                               + (list.iterator()).next());
        }
        catch (DateTimeException e) {
            System.out.println("HijrahEra is invalid");
            System.out.println("Exception thrown: " + e);
        }
    }
}
Output:
HijrahEra is: AH

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
            // HijrahDate Object
            HijrahDate hidate
                = HijrahDate.now(
                    Clock.systemDefaultZone());

            // getting HijrahChronology
            // used in HijrahDate
            HijrahChronology crono
                = hidate.getChronology();

            // getting all HijrahEras present
            // by using eras() method
            List<Era> list = crono.eras();

            // display the result
            System.out.println("HijrahEra is: "
                               + (list.iterator())
                                     .next());
        }
        catch (DateTimeException e) {
            System.out.println("HijrahEra is invalid");
            System.out.println("Exception thrown: " + e);
        }
    }
}
Output:
HijrahEra is: AH
