Check your NameRestock class. You have either...

1) Not defined the function getnumItem()
2) You defined the function but have wrong capitalization (could it be getNumItem()?)
3) Or the function is not specified as public or in a scope that can be seen by your GUI class.

So check out that class and see which one it could be. If you still can't find it, post your NameRestock class code.

Thanks for looking at this with me! I have looked at the capitilizations and did not see any problems. I made sure the getnumItem and setnumItem functions were located in the file. They are both public. Hope you can help!

There is no getaryNum(int) method defined in the class NameRestock.

Is it defined in the super-class of NameRestock?

My bad!! That was a tested error. I have the code back to original! Trying to figure it out!

Here is the error:

Anyway you see it, getnumItem() method would return an int. But you want to create an object of NameRestock, so there is definitely a type mismatch.

Also in your NameRestock class getnumItem() does not take any arguments.

He is certainly right on this one on both counts. Told you the error was back in NameRestock.

And as I told you, someone else could jump in and answer this before I could get back to you. That is the benefit of keeping your questions on the board rather than me answering this in PM for you. DIC is a team oriented environment.

Having commented out the "//NameRestock aryProd = (NameRestock) inventory.getnumItem(currentProdno);" and it does compile at this point. Realizing I have some getNumItem() issues. Shouldn't I be able to view its present contents. How do I kick this off?

[letthecolorsrumble]

There is no main() in your GUI program yet, so you won't be able to see anything.

    public static void main(String[] args) {    	
    	
    	GUI myGui = new GUI();  //not exactly this but close to this    	
    	
    }

Also the paint() method in the GUI class is missing.

"This is the fourth post that your're making about the same program.
but your' not posting all the code. this way other people may not know what
you're talking about without going back to the other posts."

*Now solution:
1) go to InventoryPart1.java and instantiate GUI -- like this

       NameRestock aryProd[] = new NameRestock[4];

      aryProd[0] = new NameRestock(1, "Hammers", 5, 20.12,"JBSandoz");
      aryProd[1] = new NameRestock(2, "Electric Drills", 3, 78.39,"ToolTime");
      aryProd[2] = new NameRestock(3, "Nails", 600, .15,"NailRoom");
      aryProd[3] = new NameRestock(4, "Wood Screws", 300, .99,"WoodHouse");


      //Sort Products.
      SortProductArray(aryProd); //call Bubble Sorth method
      System.out.println();//blank line

       // this is where you instantiate 
      // create GUI -- your passing ARRAY so go to the constructor and check parameter to ARRAY
	  GUI gui = new GUI( aryProd );

this is what you should get after compiling -- But, as you can see you still have do so
some work with the GUI ( user interface )

Thank you for Helping! I will post all future posting to this post only!
I did try to put all the code I am using. Guess I am not using the posting tools properly. So I have posted a text file that holds the code for each file. Would appreciate any feedback possible! I am seeking to understand in the minimal timeframe left!

Again Thanks!

Also, I notice you built your own GUI to check the Inventory program. I am compiling my GUI presently and it compiles properly. I realize this is not necessarily true. Apparently something is terribly wrong. Maybe I need to start from scratch. Hope not! Feedback appreciated!

No, this is the same code that you wrote, i just had to change some variable and
modify the constructor parameter to be an array.

Wanted to thank you for the help!

I have been working on the currency portion of the code and now have this corrected. I was able to manipulate some of the code you helped me with to correct my decimal placing issue.

I am now trying to get the total inventory value to show up on the GUI. I believe I am approaching this correctly but it doesn't seem to show up in the field. Again, I think I have the correct approach but maybe I am setting something up incorrectly. Can you look at my NameRestock.java file where I greated a totValue() method and tell me what I am doing wrong. See attachment!

I need to know how to add up Restock values. I created a getrestock() method that will tally up each arrays info and then add 5%. I now need to add the total array counts worth of restock prices for a grand total. Please need help soon. I have been trying all kinds of things with my NameRestock.java file. I have added gettotValue() and settotValue() methods and tried to manipulate the correct result. I have not been successful.

Here are all the files in one text file for viewing!

you don't need to declare the instance variable public double totValue in the NameRestock
you have already defined

 
     //get results
      public double getResult()
      {
         return numPrice * numUnit;
      } //end method getResult

getResult() will calculate the total amount "money" of one product "element in array"
to get the total amount of inventory "money" you need to get the result of each product and add
