I am having an bit of issue with the program I want to create a birthday reminder program that accepts the user name and birthday as an input and displays the following messages based on the user's birthday: I am trying to create birthday reminder program that accepts the user name and birthday as an input and displays one of the following messages based on the user's birthday In Java.
I figured out how to work with the dates. Right now all it does is prompt for user name and birthday, and then output the information back along with age in years and days.
I haven't yet accounted for leap years, so if the input birthday is a leap year or if the current date is a leap year, it's going to be off by a day or two.
Attached is the partial program I have written and compiled.
In the end I want the program to display these messages.
Birthday Messages to display
3) If a user's birthday is in two weeks from today's date, then the program should display. Hello , I am excited to let you know that you will be turning in days. Are you having any birthday plans? java.io.*;
