I have completed a program and it compiles fine. When I run it, it seems to run fine. The only thing is that I am missing element data for two of the objects I am printing out in the text area of this JFrame. I an array called printerProduct[5], that has three objects of type Supplier, and two of type Printer. I am needing to display the information for each object, plus a restocking fee for each object, and a total value for the entire inventory. What I don't understand is why I am missing information on one object from Supplier, and on one object from Printer. This program isn't the only one that does this. I had the instructor send me a program without the GUI code included and her's does the same thing...missing information on objects from different classes. I am not using an IDE, I am using TextPad, but I have never had a problem with this text editor before. I have included the full program below if you want to compile it and see for yourself. The items that are missing are the Supplier Name, and the Restocking Fee. I don't have many notes in the program yet, so please subdue the critique monster. I want to make sure everything works fine before I add them all.
