Lost with how to start

Dec 2nd, 2008

I have had to miss my last classes due to having to go to my doctor in order to prep me for surgery. My professor has placed the final assignment online and i have no where to begin. I'll take any help and would like to add that while i can understand programs when reading them, I am a complete lost when asked to write them. Heres the program:Implement a class named Date that
Has three instance variables (month & day & year) of type int
Has a constructor that accepts three input parametes
Has a boolean method called isBirthday
Has a method called getZodiacSign that returns the appropriate icon
Use the DateApplication class (given) as the main program

This is the code i have been given and also pictures for the zodiac symbols

Your professor already gave you basic steps on how to begin. Try those and when you get stuck, tell us what you don't understand. We won't do your assignment for you.
