Inventory program in Java

[r035198x]

Thank you, that will be appreciated. It really hurts the students when they do not write the code themselves.

A good point you make. I'll admit in this case I gave far much more than the student was giving. Very good of you to point that out. I hope you will be around more often and help to create better programmers than copy-paste type of programmers we are likely to get if students have solutions dumped at them each time.

I teach this class and I have to tell you all that I am very frustrated looking at these forums. I have students turning in these programs as you have them posted, this earns them 0's. I understand that the moderator here is trying to help, but writing code for students is not going to help them in the long run. I will be poting this site to the faculty lounges so that all faculty are aware of this site and can take appropriate action when they grade programs. It is fine to help students, but not fine to write code for them.

If you are like the teachers I have had so far, you are not teaching this class. Teaching is telling someone what they did wrong in their own programs and helping them to understand how to fix it. Not giving them the answers but guiding them to find the correct answers. This is the second time I have taken this class because I had no hope of passing it the first time. Both times everyone in each class has wondered how in the world they are going to pass it. We are reading all the textbook, usually three to four times, and most of us have purchased other books to help us try to understand what is going on. There is nothing in the text to help us to understand how to code the buttons that we need for the last two weeks. There is nothing that I have found online to help me understand it. This is the ONLY place I have found any answers at all.
I agree that students should not COPY the code, but it has been very helpful to have that code to help me understand how it is supposed to work.

I am trying to add the Delete button, save and search buttons. I have tried to call my teacher and he is absolutly no help and i have read and reread the text but still have no idea what is going on.........I have the added the add button but now i am stuck. Is there a simple way in completeing this??

Please help

• Due Date: Day 7 [Individual] forum
• Modify the Inventory Program to include an Add button, a Delete button, and a Modify button on the GUI. These buttons should allow the user to perform the corresponding actions on the item name, the number of units in stock, and the price of each unit.An item added to the inventory should have an item number one more than the previous last item.
• Add a Save button to the GUI that saves the inventory to a C:\data\invento ry.dat file.
• Use exception handling to create the directory and file if necessary.
• Add a search button to the GUI that allows the user to search for an item in the inventory by the product name. If the product is not found, the GUI should display an appropriate message. If the product is found, the GUI should display that product’s information in the
GUI. • Post as an attachment

I am having the same problem I developed the icon for add but I am lost this is my program I called this one my buttonframe

This post is no different from your first post. You obviously are not learning from your mistakes.

mistb2002 is also running his own thread in this forum here to no avail. I replied
in that thread two times now but I suspect we're dealing with a cut 'n paste code
hunter here.

btw, this thread is a total smelly wallpaper code mess ;-)

kind regards,

no I am not cutting a pasting anything I am actually in attendance at the university of phoenix and I partially have just the icon for add and I am lost in figuring out how to add the delete icon and then producing the screen for a user input. you weren't helping me so I went to another forum. I have no intentions on copying anyones work I want to do this on my own but I have been on this pc since 12am last night. I am getting truly frustrated at this program.

I was helping you but you don't realize it (yet?) I wasn't spoonfeeding you any
code but I was explaining how to post a sensible question in any forum;
I also explained how model-view-controller separation should be used in an
application. All that in your other thread.

I have the add button working......I just need help with the other.

Thanks

How did you get your add button to work I have my delete button working but I am stuck from there. this what my program looks like:

I finally got my add button to work thank god for back up disk because I did not save the correct file on my pc. I was using the correct code all along but just in the wrong order.
