    Default Basic java- objects & classes

    Hello everyone,

    I am attempting a problem in my second computer science course. I am very confused at the moment. Any help would be appreciated.


    "Create class Sess. A Sess object is to contain a reference to a Pupil object, a reference to a Tutor object and an additional attribute that refers to the date and time of an appointment between the tutor and the pupil. Write a tester that creates several Tutor objects, several Pupil objects, and several Session objects. Your tester should demonstrate that from a reference to a session you can display the data about the pupil and the tutor associated with the given visit. (You can use each of your Tutor objects and each of your Pupil objects for several Session objects.) "


    I already have made the Pupil and Tutor classes. First of all, how do I create an object that contains a reference?


    * I am currently reading information from this link:
    http://docs.oracle.com/javase/tutori...tcreation.html

    Sess object1 = new Sess();

    Pupil object1 = new Pupil();

    A Sess object that contains a reference to a Pupil object could be:
    class Sess
    {
        // a reference to a Pupil
        Pupil pupil;
     
        // a default constructor
        public Sess()
        {
            // initialize the pupil object
            pupil = new Pupil();
     
            // etc . . . 
        }
    }

    Thank you. That makes sense.. I'm trying to do some more reading on the chapter / oracle docs. I'm a long way from understanding OOP.

    Actually, that is not compiling for some reason. Geany says it cannot find the symbol. Do I need to extend Session to Pupil or something of the sort?

    Edit:

    Wow I can't even get the fundamentals right. Really need to start working harder. The problem was that I was using Geany-- I had four java files all in the same project, but it wasn't viewing them as all being together. (Is the word for that "package"?)

    I'm using BlueJ now and it compiles fine.
