Below programs illustrate the ChronoUnit.valueOf() method: Program 1:

Java

// 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

// 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);
