LocalDateTime hashCode() method in Java

The hash code value of the LocalDateTime can be obtained using the hashCode() method in the LocalDateTime class in Java. This method requires no parameters and it returns the hash code value of the LocalDateTime.

A program that demonstrates this is given as follows −

Example

 Live Demo

import java.time.*;
public class Demo {
   public static void main(String[] args) {
      LocalDateTime ldt = LocalDateTime.parse("2019-02-18T23:15:30");
      System.out.println("The LocalDateTime is: " + ldt);
      System.out.println("The hash code is: " + ldt.hashCode());
   }
}

Output

The LocalDateTime is: 2019-02-18T23:15:30
The hash code is: -388538188

Now let us understand the above program.

First the LocalDateTime is displayed. Then the hash code value of the LocalDateTime is obtained using the hashCode() method and displayed. A code snippet that demonstrates this is as follows −

LocalDateTime ldt = LocalDateTime.parse("2019-02-18T23:15:30");
System.out.println("The LocalDateTime is: " + ldt);
System.out.println("The hash code is: " + ldt.hashCode());
