Java

// Java code to show the function hashCode()
// to get the hashCode for the given period

import java.time.Period;
import java.time.temporal.ChronoUnit;

public class PeriodDemo {

    // Function to generate hashCode for the given period
    static void getNumberOfDays(int year, int months, int days)
    {
        Period period = Period.of(year, months, days);
        System.out.println(period.hashCode());
    }

    // Driver Code
    public static void main(String[] args)
    {
        int year = 12;
        int months = 3;
        int days = 31;

        getNumberOfDays(year, months, days);
    }
}

Output:

Program 2:

Java

// Java code to show the function hashCode()
// to get the hashCode for the given period

import java.time.Period;
import java.time.temporal.ChronoUnit;

public class PeriodDemo {

    // Function to generate hashCode for the given period
    static void getNumberOfDays(int year, int months, int days)
    {
        Period period = Period.of(year, months, days);
        System.out.println(period.hashCode());
    }

    // Driver Code
    public static void main(String[] args)
    {
        int year = -12;
        int months = 3;
        int days = 31;

        getNumberOfDays(year, months, days);
    }
