I have been working on an inventory program for school and it is all working.
What I need help now is making a GUI for it.
To display one item at a time with a buttons like First Item, Next Item, Previous Item, and Last Item.
Could someone help me with this project please. Thanks
Main Program
/**
* Inventory Program
* Moved out of main and added more items
* Added Grand Total for inventory
* converted to look like teachers
* Added re-stock fee per item
* Added item cost with re-stock fee added to it
* Added re-stock fee for each group of items
*/
