ChronoPeriod hashCode() method in Java with Examples

Last Updated : 27 Jun, 2019

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:

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); 
    } 
}
