JapaneseChronology eraOf() method in Java with Example

The eraOf() method of java.time.chrono.JapaneseChronology class is used to retrieve the JapaneseEra by using numeric value.

Syntax:

public JapaneseEra eraOf(int eraValue)

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

Return Value: This method returns the Japanese Era by using numeric value .

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

Example 1:

// 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
            // JapaneseDate Object
            JapaneseDate hidate
                = JapaneseDate.now();

            // getting JapaneseChronology
            // used in LocalDate
            JapaneseChronology crono
                = hidate.getChronology();

            // getting JapaneseEra for the
            // given integer value
            // by using eraOf() method
            JapaneseEra era = crono.eraOf(0);

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

Output:

JapaneseEra is: Taisho

Example 2:

// 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
            // JapaneseDate Object
            JapaneseDate hidate
                = JapaneseDate.now();

            // getting JapaneseChronology
            // used in LocalDate
            JapaneseChronology crono
                = hidate.getChronology();

            // getting JapaneseEra for the
            // given integer value
            // by using eraOf() method
            JapaneseEra era = crono.eraOf(2);

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

Output:

JapaneseEra is: Heisei
