The hashCode() method of Period class in Java is used to get the generated hashCode for this period.
Syntax:
public int hashCode()
Parameters: This method does not accepts any parameter.
Return Value: This method returns the hashCode generated for the given period.
Below programs illustrate the hashCode() method in Java:
Program 1:
// 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:
2032396
Program 2:
// 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:
2032372
