creat a product class that holds item#, name, units, and price.
display all info as well as the total value of the item inventory.
THEN I had to modify it to:
use an array to store multpile items
display one product's info at a time
and display total full value of inventory.
THEN i had to modify it again to:
create a subclass for one additional feature
create a method to calculate the value of the inventory of a product
with the same name as the method previously created for the
product class.
add a 5% restocking fee to the value of the invetory of that project.
THEN i had to modify it to:
use a GUI to display the info (my instructor commented that I could use a swing JTextField for my text display.)
I look at it and it looks confusing but my instructor said it was ok. I need to know how I can organize my code so that it is more readable, more practical and less cumbersome. I also need help with constructing my arrays; should all the doll names belong to the same array just as the item numbers, etc. OR should all the info for one doll (name, item number, units, etc.) belong to the same array OR am I missing the concept of arrays altogether? (also, my jdk won't download correctly, so I can't really test it.)

} // end method main
} // end DollInvGUI.java
After this I still need to modify it again to "add," "delete," and "modify" from the GUI and save it to a specific file as be able to search the info by product name. One last thing: what should I change to allow the item number to serve as the index so that when i add a new item it is created with the a sequential item #.
