  • This program compares the date of birth with current date and display a message indicating Happy Birthday.
  • Two Java utilities are employed: LocalDate and Month.
  • In the main method, we declare the date of birth; where birthDate stores the day and month is stored using Month utility.
  • The next step involves fetching the current date, by calling the method.
  • After that, the current day and current month is fetched using getDayOfMonth() and getDay() methods respectively.
  • In the if-condition, both the current day and month are compared with the declared DOB.
  • If the day and the month are same as the current date, then a message is printed sating HAPYY BIRTHDAY TO YOU, otherwise the console displays that Today is not your birthday.
