hello all, i just have a couple of questions (im also posting some code)

1. if you would, please take a look at my code and let me know if my compareTo method is the best way to compare what i am trying to compare. i am basically trying to make a program that will read in 3 text files, and then build 3 lists based on the info in the text files. well the class i am posting (Order) is just one of the three main classes that will be used to sort through and determine the alphabetical order the information will be in. so please take a look and tell me if it looks okay.

2. also, i am using jGrasp as my editor and i am trying to create a workbench so i can test my compareTo method. i tried to create 2 instances so i could compare them, but it keeps throwing an error when i try to enter a mock Date. the error says something along the lines of: int cannot be converted to type java.util.Date. i was just wondering why it is throwing this error?

well please take a look and please help! thanks in advance!
