The hashCode() method of ChronoPeriod class in Java is used to get the generated hashCode for this period.
Syntax:
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.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;
public class ChronoPeriodDemo {
// Function to generate hashCode for the given period
static void getNumberOfDays( int year, int months, int days)
{
ChronoPeriod 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.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;
public class ChronoPeriodDemo {
// Function to generate hashCode for the given period
static void getNumberOfDays( int year, int months, int days)
{
ChronoPeriod 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
