Inventory Control System simple(repost)

I need a simple java Inventory Control System for a small business warehouse to track items/goods. Should be a simple program its an assignement for a beginners java class. This is short fused- I need it by noon Saturday 27 March. I have two versions that I'm working on myself. But I'm a lousy programmer and my reserve unit handed me orders for 2.5 weeks duty. Java application: Inventory Control System- small warehouse/small business Requirements: -GUI interface (JOptionPane) -javadoc documentation in html -Classes- I think I only need one? InventoryItem Class -Fields- itemIdCode, itemDescription, itemName, itemCost, itemPrice, itemOnHand, itemSold -Methods -Use files to keep or save data -keep track of stock on-hand, sold and ordered units using code, price, description etc. -use array to hold data -constructor, accessor mutators? -UML Diagram (I can handle this) I might need suggestions for the actual transactions: I think the instructor will want an inventory array, then transactions to add and subtract from the inventory. Suggestions are helpful. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
