Java Program to Check the birthday and print Happy Birthday message

Example: Check birthday and return Happy Birthday message

import java.time.LocalDate;
import java.time.Month;

public class Main {
   public static void main(String args[]) {

    // declare variables for birthday
    int birthDate = 23;
    Month birthMonth = Month.SEPTEMBER;

    // get current date
    LocalDate currentDate = LocalDate.now();
    System.out.println("Todays Date: " + currentDate);

    // get current date and month
    int date = currentDate.getDayOfMonth();
    Month month = currentDate.getMonth();

    if(date == birthDate && month == birthMonth) {
      System.out.println("HAPPY BIRTHDAY TO YOU !!");
    }
    else {
      System.out.println("Today is not my birthday.");
    }
   }
}

Output 1

Todays Date: 2020-07-28
HAPPY BIRTHDAY TO YOU !!

In the above example,

• LocalDate.now() - returns the current date
• getDayOfMonth() - returns the current day
• getMonth() - returns the current month

Here, we have used the if...else statement to check if the current date matches the birthdate. If true, the Happy Birthday message is printed.
