Below programs illustrate the ChronoUnit.valueOf() method:
Program 1:
// Java program to demonstrate// ChronoUnit.valueOf() method  import java.time.temporal.ChronoUnit;  public class GFG {    public static void main(String[] args)    {          // get ChronoUnit        ChronoUnit chronoUnit            = ChronoUnit.valueOf("MILLENNIA");          // print        System.out.println("ChronoUnit: "                           + chronoUnit);    }} |
Output:
ChronoUnit: Millennia
Program 2:
// Java program to demonstrate// ChronoUnit.valueOf() method  import java.time.temporal.ChronoUnit;  public class GFG {    public static void main(String[] args)    {          // get ChronoUnit        ChronoUnit chronoUnit            = ChronoUnit.valueOf("CENTURIES");          // print        System.out.println("ChronoUnit: "                           + chronoUnit);    }} |
Output:
ChronoUnit: Centuries
