We create two Period class objects with positive and negative parameters in the code below. Then, we print the objects to the console.

import java.time.Period;
public class Main{
    public static void main(String[] args) {
        int numYears = 5;
        int numMonths = 10;
        int numDays = 13;
        Period period = Period.of(numYears, numMonths, numDays);
        System.out.println("Positive parameters - " + period);
        numYears = -5;
        numMonths = -10;
        numDays = -13;
        period = Period.of(numYears, numMonths, numDays);
        System.out.println("Negative parameters - " + period);
    }
