LocalDateTime hashCode() method in Java with Examples

The hashCode() method of an LocalDateTime class is used to return a hash code for this LocalDateTime instance. The hashcode is always the same if the object doesn’t change. This method is derived from the Object class of Java and performs in a similar way.

Syntax:

public int hashCode()

Parameter: This method does not accept any parameter.



Returns: This method returns integer value which is the hashcode value for this LocalDateTime instance.

Below programs illustrate the LocalDateTime.hashCode() method:

        // create a LocalDateTime Object
        LocalDateTime local
            = LocalDateTime.parse("2017-07-22T09:32:42");
  
        // get hashcode for LocalDateTime
        int hascode = local.hashCode();
  
        // print result
        System.out.println("hashCode value: "
                           + hascode);
    }
}
