ChronoLocalDateTime hashCode() method in Java with Examples

The hashCode() method of ChronoLocalDateTime interface in Java is used to get the hashCode value for this ChronoLocalDateTime object.

Syntax:

int hashCode()

Parameter: This method do not accepts any parameter.

Return Value: It returns an integer value which is the hashCode value for this ChronoLocalDateTime object.

Below programs illustrate the hashCode() method of ChronoLocalDateTime in Java:

Program 1:

// Program to illustrate the hashCode() method

import java.util.*;
import java.time.*;
import java.time.chrono.*;

public class GfG {
    public static void main(String[] args)
    {
        // First date
        ChronoLocalDateTime dt
            = LocalDateTime
                  .parse("2018-12-06T19:21:12");

        System.out.println(dt);

        // Get the hashCode value
        System.out.println("Hashcode: "
                           + dt.hashCode());
    }
}

Output:

2018-12-06T19:21:12
Hashcode: -957301669

Program 2:

// Program to illustrate the hashCode() method

import java.util.*;
import java.time.*;
import java.time.chrono.*;

public class GfG {
    public static void main(String[] args)
    {
        // First date
        ChronoLocalDateTime dt
            = LocalDateTime
                  .parse("2018-12-05T19:21:12");

        System.out.println(dt);

        // Get the hashCode value
        System.out.println("Hashcode: "
                           + dt.hashCode());
    }
}

Output:

2018-12-05T19:21:12
Hashcode: -957301672
