Month of() method in Java

The of() method is a built-in method of the Month ENUM which is used to generate a Month instance from an integer value. The integer value should be in the range 1-12 representing any of the 12 months and the method generates a Month instance from it representing a month-of-year.

Syntax:

public static Month of(int month)

Parameters: This method accepts a single parameter month, which is of integer type.

Return Value: This method returns the corresponding Month instance generated using the parameter passed.

Exception: This method throws a DateTimeException if the month of year passed to the parameter is not valid.

Below programs illustrate the above method:

Program 1:

import java.time.*;
import java.time.Month;
import java.time.temporal.ChronoField;

class monthEnum {
    public static void main(String[] args)
    {
        // Create a month instance
        Month month = Month.of(2);

        // Print the month Instance
        System.out.println(month);
    }
}

Output:

FEBRUARY

Program 2:

import java.time.*;
import java.time.Month;
import java.time.temporal.ChronoField;

class monthEnum {
    public static void main(String[] args)
    {
        // Create a month instance
        Month month = Month.of(12);

        // Print the month Instance
        System.out.println(month);
    }
}
