    Default My buttons will not work

    I have been working on this program for about a week and for some reason it works fine until i start adding buttons. I needed to modify my program to navigate buttons (First, Previous, Next and Last) 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 be displayed. If the last item is displayed and the user clicks on the Next button, the first item should displayed. The thing is my I keep getting error's. I think it is my packages or my imports. I must be missing something but I am not sure what?

    Here is my code:
    import java.awt.*;
    import javax.swing.*;
    import java.text.NumberFormat;
    import java.util.Locale;
    import java.util.Arrays;

    		Printer[] serialNumber = new Printer [printers.length];
     
     
    		for (int i = 0; i < printers.length; i++)
    		{
    		  productName[i] = printers[i].getProductName();
    		}
     
     
    		Arrays.sort(productName);
     
    		for (int i = 0; i < printers.length; i++)
    		{
    		     for (int j = 0; j < productName.length; j++)
    		     {
    		          if (printers[i].getProductName().equalsIgnoreCase(productName[j]))
    				  {
    				     serialNumber[j] = printers[i];

    My errors are on these lines won't copy and paste because Im using textPad unfortunately. I am getting errors like: can't find symbol for:
    1) printerIndex = 0;
    2) prepareDisplay(printerList[printerIndex], textArea);
    3) method prepareDisplay(Printer, javax.swing.JTextArea)
    4) location Class Inventory 5 centerPanel.add(prepareDisplay(printerList[printerIndex], textArea));

    And so many more. I really think I am missing a package.

    Default Re: My buttons will not work

    I took a look at your code. I strongly recommend that you download an IDE such as Eclipse or NetBeans that will check your spelling. This is why I use Eclipse. (I couldn't spell to save my life) Other than spelling, there were not too many noticable problems.

    You were right, you were missing an import (ActionEvent).

    Also you are never actually declaring the printerIndex variable in your action listeners. You have to give it a type when you declare it.


    Last thing for now. You dont have a prepareDisplay() method.

    I lied.

            private String itemNumber;
    	private String productName;
    	private int unitsInStock;
    	private double unitPrice;
    	private double totalInventory;
    	private String serialNumber;
    	private double restockFee;
    	NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.US);
     
    	//class constructor
    	public Printer (String itemNumber, String productName, int unitsInStock, double unitPrice, String serialNumber){
    		this.itemNumber = itemNumber;
    		this.productName = productName;
    		this.unitsInStock = unitsInStock;
    		this.unitPrice = unitPrice;
    		this.serialNumber = serialNumber;
    		this.restockFee = restockFee;
    	}

    You don't pass in a restockFee parameter. You are assigning this.restockFee to one of 2 things: 1) null or 2) restockFee which isn't anything at this point in the code.

    Default Re: My buttons will not work

    Thank you for your reply. First I must say that I actually uninstalled Eclipse and Netbeans because we are using TextPad and I failed my first attempt at this class because I spend too much time trying to learn those other IDE's. I did make some changes to my program but first: very confused on your last post about the restock fee I put:
    public double restockFee()
    {
    return unitPrice * .05;
    }
    Before I added the buttons my program did do everything it was suppose to, including calculate in the restock fee for each printer. I got 100% on that assignment actually. However, I am suppose to modify the program to add buttons. The First, last, previous and next buttons and also add a logo of my choice. I got my program to compile and run, unfortunately my buttons do absolutely nothing. I only added the First, last and logo for now because I am trying to break up the code in pieces. Once I get the first two buttons and logo working it will be easy to reuse the code and add the others. I'm not exactly sure where my problem is at his point but here is my code if you would not mind reviewing it for me one more time. Thank you again for your response it is greatly appreciated.

    unfortunately my buttons do absolutely nothing.
    What are they supposed to do? I see some assignment statements in the listener code.
    Try debugging your code by adding some printlns to the actionPerformed methods to show that they are being executed.



    BTW Please wrap you code in code tags not quote tags.

    Code tags are in the Go Advanced area, the # icon.
    Or just add them manually.

    Default Re: My buttons will not work

    Sorry, dah!!! (On Information overload right now, sorry) When the GUI window appears, the First printer ("brother printer" since it is in assorted array (alphabetical order)) should be displayed. The first, last, previous and next buttons should allow the user to navigate through the printers. I don't see how I am missing anything at this point (except of course the next and previous buttons I didn't add yet.)

    Default Re: My buttons will not work

    No, its not working. I have two buttons that appear in the GUI window but nothing else display's in the window. I need each printer to appear through the navigation of the buttons.
    Printer brother = new Printer("P1101", "Brother Inkjet Muliti-function Printer", 12, 217.60, "BroLM200");
    		Printer canon = new Printer("P1102","Canon Bubble Jet Photo Printer", 13, 1249.98, "CanJPH300");
    		Printer dell = new Printer("P1103", "Dell Multi-Function Laser Printer", 3, 149.99, "DelMFL400");
    		Printer hp = new Printer("P1104","HP LaserJet Printer" , 5, 149.99, "HPL500");
    		Printer lexmar = new Printer("P1105","Lexmar CLP Printer", 10, 299.98, "LexCLP600");
    		//create inventory items in array
    		final Printer[] printerList = new Printer[5];
     
    		printerList[0] = brother;
    		printerList[1] = canon;
    		printerList[2] = dell;
    		printerList[3] = hp;
    		printerList[4] = lexmar;
    Notice these are all names of printers the brother, canon, dell, hp, lexmar. When the program in run I need the first printer to display as such:
    Item Number: P1101
    Product Name: Brother Inkjet Multi-Function Printer
    Price: $217.60
    Total Value: $2611.20
    Serial Number: BroM200
    Restock Fee: $10.88
    Then when the NEXT button is clicked I need it to display the next printer ("Canon") and its Item number, product name, etc. And I need the program to navigate through the inventory as long as the buttons are pushed. As of right now I am having a problem with the buttons. They do not work. When Take the buttons and the logo code out of my program, all my inventory displays in one big window. I need each printer to display only when the buttons are clicked. I hope you understood that. ~

    Screenshot example.doc

    I have attached an example of how it should display. The buttons at the botton (SOUTH) the logo center top(NORTH) and the text should be in the middle(CENTER).

    Sorry, I don't download .doc files. Make it an image.
    What are you waiting for to make the needed changes to your code for it to display what you want?

    I was trying to get some direction or maybe some advice on where I might be going wrong with my program. But your right, this is taking too long. Thank you and have a nice day.

    You haven't designed a GUI with a slot to display things. You need a design BEFORE you write the code.

    Look at the panels you now have and where they are being positioned to be displayed.
    One set of GUI overlays another one. Go back and work on the GUI design.

    Is this a real forum or am I speaking to a computer? I do not understand what you are saying: isn't this my GUI WINDOW?

    //initialize the GUI window and set the parameters
    		JFrame frame = new JFrame();
    		frame.getContentPane().add(new JScrollPane(textArea));
    		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    		frame.pack();
    		frame.setLocationRelativeTo(null);
    		frame.setVisible(true);
    Don't worry about it I will figure it out. Thanks anyway for time.
