ChronoField values() method in Java with Examples

The values() method of ChronoField enum is used to an array containing the constants of this enum type, in the order, they are declared.

Syntax:

public static ChronoField[] values()

Parameters: This method accepts nothing.

Return value: This method returns an array containing the constants of this enum type, in the order, they are declared.

Below programs illustrate the ChronoField.values() method:
Program 1:

// Java program to demonstrate
// ChronoField.values() method

import java.time.temporal.ChronoField;

public class GFG {
    public static void main(String[] args)
    {

        // get chronoField
        ChronoField chronoField
            = ChronoField.valueOf("HOUR_OF_DAY");

        // apply values()
        ChronoField[] array
            = chronoField.values();

        // print
        for (int i = 0; i < array.length; i++)
            System.out.println(array[i]);
    }
}

Output:

NanoOfSecond
NanoOfDay
MicroOfSecond
MicroOfDay
MilliOfSecond
MilliOfDay
SecondOfMinute
SecondOfDay
MinuteOfHour
MinuteOfDay
HourOfAmPm
ClockHourOfAmPm
HourOfDay

Program 2:

// Java program to demonstrate
// ChronoField.values() method

import java.time.temporal.ChronoField;

public class GFG {
    public static void main(String[] args)
    {

        // get chronoField
        ChronoField chronoField
            = ChronoField.valueOf("HOUR_OF_DAY");

        // apply values()
        ChronoField[] array
            = chronoField.values();

        // print
        System.out.println("ChronoField length:"
                           + array.length);
    }
}

Output:

ChronoField length:30
