Year year = Year.of(2022);

Getting Information About a Year

Year nextYear = year.plusYears(1);
Year previousYear = year.minusYears(1);

boolean isAfter = nextYear.isAfter(year);
boolean isBefore = previousYear.isBefore(year);

Conclusion

The Year class provides a convenient way to work with years in Java8. It offers various methods for getting information about a year, performing operations on a year, etc. This class can be useful in many applications that deal with date and time.
