Hedging my bets, I have coded a simpler version of the program Ezzaral is helping me with. I fear I am in over my head over there and may just begin to annoy him with silly questions.
Most of what he and I are working on is beyond the scope of my class anyways, so I did not mind trying to learn more as it made class simpler. I do not want to end up without a working program to turn in though, so I set out on this one this morning.
I am only having one issue at the moment, and it is with "super".
I am not sure why it is not working in this class.
I am getting cannot find symbol, and I do not understand why.
Can anyone offer assistance?

which compiles fine. If you need to see the primary class just let me know, but everything looks fine to me here.
Any help would be welcome.

Crap. Just when I say I am doing fine I get these messages when I compile my main class.

I think some of my logic may be off. I have taken the day off work tomorrow to try and work through one or both of these programs to completion. The more coding experience I can get under my best with either application the better. Finals are coming up in a couple weeks.

Thanks again to anyone willing to help.

Here is the panel to that class just in case you want to see it.

Again, you are trying to use the integer index value like an object. You need to actually get that object (using currCD as the index) from your listModel as a CdwArtist object.

I knew that was the same error. I do not know why I cannot get that straight in my head.
I will work on that this evening.
Other than that, how does this look, as you are so familiar with the other version.

It looks like you are getting a lot closer to something that will work out. I don't see any way for a user to add a CD though and you have already filled your array to the hard-coded max of 5 items. I assume you have put that part in to test the workings of your first(), last(), etc. methods?

Comments
Always has a suggestion

You are correct. With this one I am not going above and beyond anything that is being requested.
All I want with this is to be able to display the elements of the array one at a time, and perform those pesky calculations of course.
I will put an add and del button in sometime over the next few weeks if I stick with this one.

I am closing this out. I have put too much time into the other code to abandon it now.

This question has already been answered. Start a new discussion instead.
