    If you look inside your customer class you will see a comment:

    // Add constructor, get, set, as needed.

    So it looks like you are supposed to write code here. The error exists because the code you need to write does NOT exist.
    You need to write the methods(the Customer constructor also needs to be written. The constructor is what is being called where the error is, but the constructor hasn't been written yet) in the Customer class so that the call where you are getting the error is no longer an error.

    I second what Greg said. Check out the link that he posted. The first page alone should give you enough information on how you need to define your constructor.

    A constructor looks like a method, it has no return type, and it has the same name as the class that it is in. They are called on (as in line 51 of your code) to create objects from your class.

    Not to throw everything at you at once, but after the constructor is created you will still most likely need set and get methods in the Customer class. Here is one link that could get you familiarized with what they look like: http://stackoverflow.com/questions/1...uctors-in-java
