ChronoUnit values() method in Java with Examples
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
