    Default Warehouse application?

    Hello,

    I've recieved an "over the holidays" task to preform, that task is to create a "warehouse application" in Java but my instructions are, in all fairness, too lousy to get me started on it. So, I was wondering (and hoping) that maybe someone here could help me understand how i need to get started

    My instructions:

    "Create a warehouse application into which the user can, with the help of GUI, add items with Name, Quantity and Price in an array. One should be able to see these items as well as the total value of each item. Value = quantity*price.

    Furthermore a value for the warehouse total should be seen"


    Now i understand what the end result is supposed to be, a simple GUI with input boxes and either a TextArea or Panel for output. But I have, as mentioned, no idea how to get started with the actual functions.

    I've gotten as far as that i'll need to create a Class for it but that's about it...

    Would be very grateful if someone could try and explain to me what needs to be done.

    Thank you kindly

    Hello and welcome to the forums.

    First, I would create the GUI. Take a look at this link:

    Trail: Creating a GUI With JFC/Swing (The Java™ Tutorials)

    When the GUI is complete, you can create the functionality.

    Take a look at our Java Code Snippets and Tutorials forum. There are code examples there.

    For example:

    http://www.javaprogrammingforums.com...ava-swing.html


    Post back with the code you have and we can take it from there..

    Hi again,

    Seeing as the original instruction was, to me, insufficient, i asked for something more to go on and was told the following:

    "Create a class 'LagerVara' with constructor to set instancedata like name(String), quantity(int) and price(double) as well as get-methods to collect said instancedata"

    Allthough this helped a bit, i'm still a bit confused. Since the input data is supposed to be saved into an array and such I'm not entirely sure how to go about it.

    Here's what i've gotten so far (very basic still)

    This is the GUI in graphical view, TextArea to show information, TextFields to enter information, and a button.


    I haven't entered any actual coding into the GUI yet.

    The class, LagerVara, currently looks like this:

    public class LagerVara {
     
        private String namn=null;
        private double pris=0;
        private int antal=0;
     
     
     
    public LagerVara (String namn){
     
    }
     
    public LagerVara (double pris){
     
    }
     
    public LagerVara (int antal){
     
    }
     
    public String getNamn (String namn){
        return ;
    }
     
    public double getPris (double pris){
        return ;
    }
     
    public int getAntal (int antal){
        return ;
    }
     
    }

    What i'm currently pondering is, do i put the Array (in which the information is to be stored) in the class or GUI? I'm leaning towards putting it in the class?

    And, if it goes in the class, won't i need set-methods as well?


    PS. Sorry for the crude images, Paint is currently all i have to work with

    Edit: forgot to mention, I'm doing all of this using NetBeans 6.9.1 just so i've said that too

    Hi again,

    Just thought I'd wrap this up, solved the "puzzle" so to say ^^

    What i did was this:


    Class:

    public class LagerVara {
     
        private String namn;
        private double pris;
        private int antal;
     
    public LagerVara (){
        //tom konstruktor
    }
     
     
    public LagerVara (String namn){
    this.namn=namn;
    }
     
    public LagerVara (double pris){
    this.pris=pris;
    }
     
    public LagerVara (int antal){
    this.antal=antal;
    }
     
    public String getNamn (){
        this.namn=namn;
        return this.namn ;
    }
     
    public double getPris (){
        this.pris=pris;
        return this.pris ;
    }
     
    public int getAntal (){
        this.antal=antal;
        return this.antal ;
    }
     
    public void setNamn (String namn){
        this.namn=namn;
     
    }
     
    public void setPris (double pris){
        this.pris=pris;
     
    }
     
    public void setAntal (int antal){
        this.antal=antal;
     
    }
     
     
     
    }

    and the GUI code turned out like this:

    LagerVara l=new LagerVara();
    String LagerVaror [][]=new String [30][4];
    double total=0;
    double lvarde=0;
    int index=0;
        private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
            // TODO add your handling code here:
            jTextArea1.setText(null);
     
            l.setNamn(jTextField1.getText());
            l.setPris(Double.parseDouble(jTextField2.getText()));
            l.setAntal(Integer.parseInt(jTextField3.getText()));
     
     
     
            LagerVaror[index][0] = l.getNamn();
            LagerVaror[index][1] = String.valueOf(l.getPris());
            LagerVaror[index][2] = String.valueOf(l.getAntal());
            LagerVaror[index][3] = String.valueOf((l.getPris()*l.getAntal()));
            index++;
     
            total=l.getPris()*l.getAntal();
     
            for (int i = 0; i < index; i++){
            jTextArea1.append("Varunamn: " + LagerVaror[i][0] +"     "
                    + "Pris: " + LagerVaror[i][1] +"     "
                    + "Antal: " + LagerVaror[i][2] +"     "
                    + "Värde: " + LagerVaror[i][3] +"\n");
            total=total+total;
            }
            jTextArea1.append("LagerVärde: " +total);
     
        }


    Now to have some fun the rest of the day before diving into the next problem tomorrow
