Hey check out my prog. It has an error can u find it?

[buggytoast]

Hi everyone! (it's been awhile XD)
I've gone and done my homework. And here I am with a program that works...pretty well I think.

There appears to be a problem with the saving/loading. Originally it worked without a problem, but when I attempted to make it more graphically friendly (when it displays in the list), the file saves, however I can't load it in panel 2.

You can get a 'Load Model Set', by just copy pasting the data below. Put it into a text file. (notepad)

48-209-351 1.3 300 5
60-344-351 1.45 250 12
72-554-351 1.32 200 9
84-754-351 1.35 350 3
96-1042-351 1.4 280 7

As I said before, originally it works, but now it doesn't. I'm nearing a deadline and I have to do uber documentation, can anyone help? I hope this is enough effort lol. Peace guys :D

PLEASE DO NOT COPY!!!!!!!

And Finally Models here

    private double height;

    private int group;

    // Blank constructor
    public Model()
    {}

    // Enter values for model information
    public Model(String modelNo, double height, int tipNum, int group)
    {
        setModelNo(modelNo);
        setHeight(height);
        setTipNum(tipNum);
        setGroup(group);
    }

    // Model number methods
    public void setModelNo(String modelNo)
    {this.modelNo = modelNo;}

    public String getModelNo()
    {return modelNo;}

    // Height methods
    public void setHeight(double height)
    {this.height = height;}

    public double getHeight()
    {return height;}

    // tipNum methods
    public void setTipNum(int tipNum)
    {this.tipNum = tipNum;}

    public int getTipNum()
    {return tipNum;}

    // group methods
    public void setGroup(int group)
    {this.group = group;}

    public int getGroup()
    {return group;}
}

It's probably a really basic problem but i can't seem to pinpoint it. Thanks in advance guys.

[Phaelax]

It'd help if you described to us whats not working. Whats the intended affect? whats it doing instead? Can you just not read the file back in, or is it that you cant get it to display?

[buggytoast]

Sincerest apologies. What happens is that I save the file no problem however when I move to panel 2 to load the file, it fails to display. Hope that covers everything. PEace.

Not bigger mistake..... yaar ....

For the Scanner object,
inside OrderList(File inFile, Component c) constructor ... you are setting Delimiter to "\t" just remove that line or comment that line.... and you will be aware from your nightmare..... thats it... do it fast.........

just check out the definition of :

public Scanner useDelimiter(Pattern pattern)
Sets this scanner's delimiting pattern to the specified pattern.

Parameters :
pattern - A delimiting pattern
Returns:
this scanner

since that pattern is not matching so its not reading properly but actually it can read first value then goes to nextline wherin it does the same..... so by commenting that line your program will definitely work.

ALTERNATIVE:

check out toString() implementation of TreeData there u are not specifying the space value equals to "\t" and same no. of spaces are being written to file ... therefore while reading from a file its not doing well......

Nilesh................. :)

[buggytoast]

Hey thanks everyone...It works now :D.

BTW as a side note, my teacher doesn't want me to use "vectors" cuz it shows implementation and not "mastery". I just go get the source code and change the variables right?
