Hey there everyone, I am currently working on and Assignment that is due tonight and I feel like I am close but can not exactly get to the end. I would appreciate any feedback possible. Kinda stuck at the moment.
---Modify the Inventory Program to use a GUI. The GUI should display the information one product at a time, including the item number, the name of the product, the number of units in stock, the price of each unit, and the value of the inventory of that product. In addition, the GUI should display the value of the entire inventory, the additional attribute, and the restocking fee.

---Modify the Inventory Program by adding a button to the GUI that allows the user to move to the first item, the previous item, the next item, and the last item in the inventory. If the first item is displayed and the user clicks on the Previous button, the last item should display. If the last item is displayed and the user clicks on the Next button, the first item should display

That is what I must finish and I will post the code I have so far beneath this.

I am having a hard part grasping the GUI part that I need to get to display the Array with. Thanks!

update the GUI part to where I am now. Still now getting it to work right.

Not asking for much, are you? You want us to analyze 430+ lines of code. Reduce it to the sections that you are having problems with. FWIW, I charge my clients $200USD per hour to analyze their code, and this will take at least a couple of hours to do properly.

Sorry did not mean to come off that way. I usually see people posting very little and everyone says, what you want us to do it all for you? I already have most of it done. The only real questions would be trying to get the array to display in the GUI.I am extremely new to Java and this assignment is driving me crazy. The main question I have I guess is where I made it comments in lines 99-100. For some reason I can not pull the arrray with the item.get method. I feel like I have almost all of it finished but then again maybe I am way off.

Cripop: posting little is usually good, if it contains all the relevant code/information.

In your classes, you don't follow naming conventions, you have a number of (static) methods in your classes that I can't imagine what you would need them for ...

If you need to show all the elements of the array at the same time, either show a series of JTextFields underneath each other, or use a JTable, each row representing an element.

Hi Cripop
It's good that you have already done so much, and posted yur progress so far. What's missing is a clear and concise statement of exactly what help you need. You can't expect people to read the spec, read yur code, and figure out which bit(s) you haven't done yet.

Anyway
Where you have
itemNumber.setText(String.valueOf(item.getdvdNumber()));
etc, you need to replace item by a reference to the current member of the array of DVD objects. For that you'll need a variable to hold the index of the current member Previous and next then are just decrementing or incrementing that index and updating the display.
