New to Java

my teacher give this as a problem. so tough. we are just starting and we are now in control structures. please help me to finish this problem. And my problem is...

Write an astrology program. The user types in his or her birthday(month,day,year),
and the program responds with the user's zodiac sign, the traits associated with each sign
the user's age(in years,months,day), the animal sign for the year(e.g., Year of the Pig,
Year of the Tiger), the traits associated with each animal sign, and if the year is a leap
year or not. The dates covered for each sign can be searched through the horoscope section
of a newspaper or through the internet. Then enhance your program so that if the user is one
or two days away from the adjacent sign, the program outputs the nearest adjacent sign as well
as the traits associated with the nearest sign. The month may be entered as a number from 1 to 12
or in words, i.e.,January to December. Limit the year of the birthday from 1900 to 2010 only.
The program should allow the user to repeat the entire process as often as desired.
You can use:
import java.text.DateFormat;
import java.util.Date;
import java.util.Calendar;

please...those who are genius out there in java program...help us to pass this project. Im begging! thanks!
