GUI Not Launching

Question

Hi Everyone I am new and just found this site yesturday I am looking forward to visiting here often.

I have been working on this project (yes for school the awful Inventory Program.)

I had it working and did a couple of quick changes walked away for a nap and now it won't launch the GUI and I didn't take notes on what I did.
Everything looks like it is there so now I am going through my code and checking to see if something is causing it not to launch or if I accidently deleted something when I was cleaning it up to turn in.

I was just wondering if I could invite you to look with me :$
I feel so stupid about this but I am so tired and my brain is mush :zzz:

I thank those who are up to the challenge in advance.

Here is my code

package inventoryfinal;

import java.text.Collator;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.Locale;

public class Inventory {

   private String inventoryName; // name of inventory

   public String restockRate; // restock rate percentage

   public double totalRestock;

   public static int index;

   public ArrayList < ProductModified > products = new ArrayList < ProductModified > ();

   public Inventory()
   {
      products.add( new ProductModified( "Wanted", 0, 1, 0.00 ) );
      products.add( new ProductModified( "Death Race", 7, 52, 160.00 ) );
      products.add( new ProductModified( "Harry Potter", 16, 61, 97.00 ) );
      products.add( new ProductModified( "Repo", 25, 106, 88.00 ) );
      products.add( new ProductModified( "Matrix", 34, 125, 79.00 ) );
      products.add( new ProductModified( "Mamma Mia", 0, 124, 70.00 ) );

      index = 0;
   }

   public void sort()
   {
      Locale loc = Locale.ENGLISH;

      ProductModified Temp;

      Collator col = Collator.getInstance( loc );

      for ( int i = 0; i < products.size(); i++ )
      {
         for ( int j = i + 1; j < products.size(); j++ )
         {
            if( col.compare( products.get( i ).getDVDName(), products.get( j ).getDVDName() ) > 0 )
            {
               Temp = products.get( i );

               products.set( i, products.get( j ) );

Hello bunifrog.
Initialize imageLabel.
Temporaily delete ProductModified. You can use function with a coefficient value 1.0 or 1.05 to calculate inventoryValue().

You posted much too much code. If your GUI isn't launching it is probably because you didn't call setVisible(true) on the JFrame, but who knows since I didn't manage to find your main method after scrolling through.

quuba thanks so much for answering I really am gratefull.

I did as you said and it messed up all of the classes.
Not sure how you ment for me to do it but again thanks for answering I am just so new at this and after 4 days it is all blurring together.

After doing ctrl+f to find your code, then doing it again to find your constructor for InventoryDialog, it seems like your GUI isn't launching because you never added the panel to the frame. Your "main" panel is called cp. You should have called this.add(cp) somewhere, since your class extends JFrame, but it doesn't look like you did. So unless I missed where you did that, when you run your code, you would see nothing but an empty JFrame. Also, make sure you called setVisible(true) somewhere after everything is added to the JFrame also.

Second view to inventoryfinal:
Inside InventoryGUI constructor
//1. scrollPane.setPreferredSize(new Dimension(250, 250)); not needed
//2.

JPanel cp = new JPanel(){
            public Dimension getPreferredSize(){
                return new  Dimension(500, 200);
            }
        };

//3. cp.setSize(350, 40); pack() change this
//4. cp.add(imageLabel, BorderLayout.EAST); imageLabel not initialized
//5. this.setSize(400, 400); if pack() - no needed
//6. Container pane = getContentPane();
//7. pane.setLayout(new GridLayout(4, 2)); another one layout?

Inside ProductModified class
//8.private String MovieName; - not used, always null
//9.

public String toString() {
        return "\n" + this.productNumber + "\t" + this.getDVDName() + "\t" + this.unit + "\t" + this.price + "\t" + this.getInventoryValue();
    }

Comment some lines, change 2., 9.
Previously I wrote delete. Don't do it.

Thanks everyone you know you get to a point when it all just goes blurry and I had redone the code so many times by this point I lost the flow of it all. I managed to get it all rewrote and turned in on time but it is going to take me a week to recover from this week.

Again thanks everyone for posting It at least gives me something to play with later as I am going to practice until my next class starts lol.
