Return Value: It returns a suitable integral hash code for the year object with which it is used. It never returns a NULL value.
Below programs illustrate the hashCode() method of Year in Java:
Program 1:
// Program to illustrate the hashCode() method  import java.util.*;import java.time.*;  public class GfG {    public static void main(String[] args)    {        // Creates a Year object        Year firstYear = Year.of(1997);          // Print the hash code for        // the current year object        System.out.println(firstYear.hashCode());    }} |
Output:
1997
Program 2:
// Program to illustrate the hashCode() method  import java.util.*;import java.time.*;  public class GfG {    public static void main(String[] args)    {        // Creates a Year object        Year firstYear = Year.of(2018);          // Print the hash code for        // the current year object        System.out.println(firstYear.hashCode());    }} |
Output:
2018
