HijrahChronology eraOf() method in Java with Example

Last Updated : 28 Apr, 2022

The eraOf() method of java.time.chrono.HijrahChronology class is used to retrieve the Hijrah Era by using numeric value 1 because HijrahChronology contains only one HijrahEra. 

Syntax:

public HijrahEra eraOf(int eraValue)

Parameter: This method takes the eraValue integer as a parameter for which HijrahEra is going to be generated. 

Return Value: This method returns the Hijrah Era by using numeric value 1 because HijrahChronology contains only one HijrahEra . 

Below are the examples to illustrate the eraOf() method:

 Example 1: 

Java 
// Java program to demonstrate
// eraOf() 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 HijrahEra for the
            // given integer value
            // by using eraOf() method
            HijrahEra era = crono.eraOf(1);

            // display the result
            System.out.println("HijrahEra is: "
                               + era);
        }
        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
// eraOf() 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 HijrahEra for the
            // given integer value
            // by using eraOf() method
            HijrahEra era = crono.eraOf(0);

            // display the result
            System.out.println("HijrahEra is: "
                               + era);
        }
        catch (DateTimeException e) {
            System.out.println("HijrahEra is invalid");
            System.out.println("Exception thrown: " + e);
        }
    }
}
Output:
HijrahEra is invalid
Exception thrown: java.time.DateTimeException: invalid Hijrah era
