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());     } } |
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());     } } |
