Inventory Program part 6

[mistb2002]

I am trying to modify my program to add and delete inventory items. I tried just adding but I am getting mutliple errors help.

This is what my program currently looks like

I am trying to modify my program to add and delete inventory items. I tried just adding but I am getting mutliple errors help.

We're not here to find your errors and you're not here to play hide-'n-seek. When
you find errors, whether they are compiler errors or runtime errors you should at
least supply as much information as possible, and not post more than 200 lines
of code without anything to guide your reading audience where the problem
might be.

Compiler errors and warning diagnostics display a nice line and column number
indicating *where* the compilation failed, together with a friendly error message.
Runtime errors try to do the same, together with a nice stack backtrace.

Please try again if you want a sensible answer and only supply the relevant
snippets of code, not long listings of wallpaper because nobody is going to read
all that for you and seek where the error might be hiding.

kind regards,

Jos

What a nice way of putting things ! :( I will recompile and give you the error brb

[mistb2002]

Okay I am trying to write the program to allow user input for a dvd database.

I am trying to create prompt that once add is selected another field opens allowing user input. so far I have the icon for add but I cannot develop the code for this

Okay I am trying to write the program to allow user input for a dvd database.

I am trying to create prompt that once add is selected another field opens allowing user input. so far I have the icon for add but I cannot develop the code for this

Don't do it that way: first develop a method that can add a new DVD to your
set (database or whatever) of DVDs; all necessary values are supplied to that
method. If that works turn back to those JComponents again were a user can
supply those necessary values in nice JTextFields or whatever.

Decoupling the business logic (that 'addDVD' method, see above) from the view
is a first step towards a nice MVC pattern design. Think of it this was: your DVD
model doesn't care where those parameter values come from, as long as they
are correct. Your controller software doesn't care how those parameters were
obtained but check for their correctness. The view doesn't know what it's doing,
i.e. it just allows the user to enter values and pass them on to the controller.

kind regards,

Jos

I apologized I was too impatient and went to another post for help I am new to this and I thank you. I am taking a deserve break to eat and will resume in 1 hour. noone ever told me java was going to be this hard.

No harm done ;-) It's not Java that is the hard part; it's the entire concept of
programming in an object oriented way; as a matter of fact, Java even flattens
the steep learning curve if you compare it to, say, C++.

I finaly got it I was on the right track by adding the JButtons for delete and add but now when I am running the program it is doing the opposite the delete is adding and the adding is deleting. look this is my ButtonFrame:

[B]what am i doing wrong?

[mistb2002]

I enjoy breaking and fixing a pc rather than programming. programming keeps me up all hours of the night. I'm starting to eat drink and sleep JAVA[ mainly how to improve my program] The first thing I did when I came home was hit the pc to work on my program, I did not even greet my daughter. this is baaaad!

Hey that how I feel I'm starting to eat, drink and sleep JAVA. I wake up think about java, infact I try to help other in Java either here on thescripts or Java main tech forum. I even started writing a article of Arraylist in which Jos talked me into and I still have to finish it, and I just took one course...
good grief...
JAVA Java java, my wife is calling me. Good night....

I cannot get this program to add can you take a look?
