LocalDateTime hashCode() method in Java with Examples

Last Updated : 09 Dec, 2022

The hashCode() method of a 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:

Program 1:

Java

// Java program to demonstrate
// LocalDateTime.hashCode() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {

        // create a LocalDateTime Object
        LocalDateTime local
            = LocalDateTime.parse("2017-07-22T09:32:42");

        // get hashcode for LocalDateTime
        int hashcode = local.hashCode();

        // print result
        System.out.println("hashCode value: "
                           + hashcode);
    }
}

Output:

hashCode value: -2030906730

Program 2:

Java

// Java program to demonstrate
// LocalDateTime.hashCode() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {

        // create a LocalDateTime Object
        LocalDateTime local
            = LocalDateTime.parse("2006-01-02T19:32:42");

        // get hashcode for LocalDateTime
        int hashcode = local.hashCode();

        // print result
        System.out.println("hashCode value: "
                           + hashcode);
    }
}

Output:

hashCode value: 1849330620
