Misplaced bracket error in code

[Gina777416]

I cannot figure out why my main is not identifying my classes, is there a bracket misplaced or something? Here are the errors I am getting

C:\Documents and Settings\Regina Denson\My Documents\JCreator LE\MyProjects\Inventory6.java:37: cannot find symbol
symbol  : class GUI
location: class Inventory6
        GUI gui = new GUI(inventory); // Start the GUI

And Here is my code

Please HELP[/CODE]

Hi, Gina!

I do not see where you declare the class GUI. If it is in a different package, you will need to import it before using it.

import packagename.GUI ;

kind of like you're importing the java.util package contents.

[samido]

dude, make sure the class GUI is compiled successfully, this is why you getting this problem, chaww...

Thanks so much!! So I add that import line under the first import line?

The compiler is complaining because you have no constructor written for the Inventory class that takes an Inventory parameter, which I would assume is a copy constructor, which would assign the member values of the input Inventory to the newly constructed Inventory object.

Eg:
[CODE=java]
public class Foo {
private int a;
public Foo(Foo other){//Takes a parameter of a Foo object
a = other.a; //Assigns a to the input object's a value
}
...
}
[/CODE]

I am so new at this I guess I just don't understand the whole "Foo" thing. But thank you so much for your reply

[Laharl]

The Foo class was an example to give you an idea of what this needs to look like. The type of constructor I mentioned is called a "copy constructor" because it makes the new object a copy of the old one.
