Example:

例：

// Java program to demonstrate the example 
// of int hashCode() method of Instant
import java.time.*;
public class HashCodeOfInstant {
public static void main(String args[]) {
// Instantiates two Instant
Instant ins1 = Instant.parse("2006-04-03T05:10:15.00Z");
Instant ins2 = Instant.now();
// Display ins1,ins2
System.out.println("Instant ins1 and ins2: ");
System.out.println("ins1: " + ins1);
System.out.println("ins2: " + ins2);
System.out.println();
// Here, this method returns the
// hash code value for this Instant 
// ins1
int hash_code = ins1.hashCode();
// Display hash_code
System.out.println("ins1.hashCode(): " + hash_code);
// Here, this method returns the 
// hash code value for this Instant 
// ins2
hash_code = ins2.hashCode();
// Display hash_code
System.out.println("ins2.hashCode(): " + hash_code);
}
}

Output
