Adding a Restock Fee

[r035198x]

Lol!

kind regards,

Jos :-)

I just googled it.
Silly me

[nexcompac]

You googled Lysol? Funny....
For some reason I am having troubles with TextPad and the way it complies on my home computer. My laptop works just fine, but I can not use it at work. My work computer does not have permission to install the JDK files and its not worth "tweeking" it at the moment. So, I need to wait until I get home unless you have a way of doing it without requireing the Admin password.

About the complie stuff. Since my computer has issues, I copy the *.java files into the bin folder of the JDK and then compile from the comand prompt by changing the directory to the bin file and typing javac *.java. This will compile all the java files and give me the *.class files. Then, I can just fire the java files from the cmd too. Does that make sence?

It sort of works but you shouldn't do it like that: add the name of that bin directory
to your 'path' environment variable and store your .java sources and .class files
somewhere else in their own directory. You don't pollute that bin directory then.

Hi,
luk at ur getRestockFee() method again........ here u r calling value method in ur return statement..... but there is no value method in ur class.....thats why compiler is not able to resolve it... it is not wise to remove the lines where u r getting errors...... instead u should think what u need to resolve this error.... I think r035198x has given u the answer.....defi ne value() method in ur class

thanks and regards,

Ok, so should this be defined in the current class which it resides in or should it be designed in the public main class?

See one of your error messages again:

 Product.java:61 cannot find symbol
symbol  : method value<>
location: class product
      return value<> * 0.05;

Ok, so now I am getting just one error.
Again just typing out manually.
product.java:8: ';' expected

Here is what I changed

}

Hi,
put a semicolon at the end of this line.....

private double restockfee

like this

private double restockfee;

Thanks and regards,

ok, so now I am going in circles.....

Heres what someone pointed out to me.

And your problem is that you did not and still have not defined a value() method. Typically, methods need to exist before you use them

That is ever so true; I tried to find the definition of the value() method in your
post but it was nowhere to be found. Define a method value() in your class:

[code=java]
double value() {
return //whatever it has to return
}
[/code]

and try again.

Jos

Ok, so what is the best method in proceeding to add the GUI to this?

I don't know; I don't know what sort of GUI you have in mind. Have you read
about the Swing framework? Look here.
