The values() method of ChronoUnit enum is used to an array containing the units of this ChronoUnit, in the order, they are declared.
Syntax:
public static ChronoUnit[] values()
Parameters: NA
Return value: This method returns an array containing the constants of this enum type, in the order, they are declared. Below programs illustrate the ChronoUnit.values() method:
Program 1:Â
Java
// Java program to demonstrate// ChronoUnit.values() methodÂ
import java.time.temporal.ChronoUnit;Â
public class GFG {Â
    // Main driver method    public static void main(String[] args)    {        // get ChronoUnit        ChronoUnit chronounit            = ChronoUnit.valueOf(" FOREVER & quot;);Â
        // apply values()        ChronoUnit[] array = chronounit.values();Â
        // print        for (int i = 0; i & lt; array.length; i++)            System.out.println(array[i]);    }} |
Output:
Nanos Micros Millis Seconds Minutes Hours HalfDays Days Weeks Months Years Decades Centuries Millennia Eras Forever
Program 2:Â
Java
// Java program to demonstrate// ChronoUnit.values() methodÂ
import java.time.temporal.ChronoUnit;Â
public class GFG {Â Â Â Â public static void main(String[] args)Â Â Â Â {Â
        // get ChronoUnit        ChronoUnit chronounit            = ChronoUnit.valueOf("CENTURIES");Â
        // apply values()        ChronoUnit[] array            = chronounit.values();Â
        // print        System.out.println("ChronoUnit length:"                           + array.length);    }} |
Output:
ChronoUnit length:16
Program 3:
Java
import java.io.*;import java.time.temporal.ChronoUnit;Â
// classpublic class GFG {       // Main driver method  public static void main(String[] args)    {               ChronoUnit[] units = ChronoUnit.values();        ChronoUnit smallest = units[0];        ChronoUnit largest = units[0];           // Iterating using enhanced for each loop    for (ChronoUnit unit : units) {            if (unit.compareTo(smallest) < 0) {                smallest = unit;            }            if (unit.compareTo(largest) > 0) {                largest = unit;            }        }         // Print statements        System.out.println("Smallest unit: " + smallest);        System.out.println("Largest unit: " + largest);    }} |
Output:
Smallest unit: Nanos Largest unit: Forever
