Instant hashCode() method in Java with Examples

Last Updated : 27 Nov, 2018

The hashCode() method of Instant Class is used to get hashCode for this Instant. The hashcode is always the same if the object doesn’t change. Hashcode is a unique code generated by the JVM at time of object creation. It can be used to perform some operation on hashing related algorithm like hashtable, hashmap etc. An object can also be searched with its unique code (hashcode).

Syntax:

public int hashCode()

Returns: This method returns the hashCode for this Instant.

Below programs illustrate the Instant.hashCode() method:

Program 1:

// Java program to demonstrate 
// Instant.hashCode() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a Instant object 
        Instant instant 
            = Instant.parse("2018-12-30T19:34:50.63Z"); 
  
        // get hashCode 
        // using hashCode() 
        int value = instant.hashCode(); 
  
        // print result 
        System.out.println("hashCode value: "
                           + value); 
    } 
} 

Output:

hashCode value: -683539878

Program 2:

// Java program to demonstrate 
// Instant.hashCode() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a Instant object 
        Instant instant = Instant.now(); 
  
        // current Instant 
        System.out.println("Current Instant: "
                           + instant); 
  
        // get hashCode 
        // using hashCode() 
        int value = instant.hashCode(); 
  
        // print result 
        System.out.println("hashCode value: "
                           + value); 
    } 
} 

Output:

Current Instant: 2018-11-27T04:45:52.428Z
hashCode value: 1896457472
