Enummeration/Loop help

[javahelpneeded]

I am needing help writing a program in which every month of the year is enumerated. It needs to run so that the user can input a day of the year in the format mm/dd/yyyy and the output be the day number in the year (the 3 of feb would be the 31 of jan plus 3 = 34), the date in the form dd/mmm/yyyy, and the year, and still being able to factor in leap years.

I'm just starting out in java and our teacher really hasn't taught us this stuff at all, and the book bites. Help would be greatly appreciated.
