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:
Java
// Java program to demonstrate// ChronoUnit.values() methodimport java.time.temporal.ChronoUnit;public class GFG { // Main driver method public static void main(String[] args) { // get ChronoUnit ChronoUnit chronounit = ChronoUnit.valueOf(" FOREVER & quot;); // apply values() ChronoUnit[] array = chronounit.values(); // 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:
Java
// Java program to demonstrate// ChronoUnit.values() methodimport java.time.temporal.ChronoUnit;public class GFG { public static void main(String[] args) { // get ChronoUnit ChronoUnit chronounit = ChronoUnit.valueOf("CENTURIES"); // apply values() ChronoUnit[] array = chronounit.values(); // print System.out.println("ChronoUnit length:" + array.length); }} |
Output:
ChronoUnit length:16
Program 3:
Java
import java.io.*;import java.time.temporal.ChronoUnit;// 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
