Package structure

Question

Well i actually develop a soft and i have a little question about packages structure.
My application is composed is composed of a main JFrame with a JDesktopPane and
a primary JInternalFrame. Some others JIF are used and in order to make it clear,
i try to use this structure for the implementation.
In my main directory, the Gui is placed. All the JIF are placed in a subdirectory called
GuiFrames (and also as a package GuiFrames). For some reasons, I have to give the Gui class
as argument to the JIF in order to keep a link to the main frame when switching from one
JIF to another (there will be only one JIF visible in the JFrame).
The problem is that the reference i use (ie the mainclass name) throw me to a
"can't resolve symbol ..." problem. I don't know how to make a reference to a class that is just above in such a structure.
let's resume it through this small draw :
MainClass.java
|
|
--> Package GuiFrames
.... |
.... --> JIFrameOne.java
.... |
.... --> JIFrameTwo.java
.... |
.... --> JIFrameThree.java
.... |
.... --> JIFrameFour.java
.... |
.... --> JIFrameFive.java
In each JIFramexxxx.java, i need a link to MainClass.java, but MainClass.java can't be found from the package GuiFrames.
Any suggestion would be welcome.
Marc.
PS: the easiest way would be to put all the JIF in the same directory as the MainClass, but i would avoid this for some development reasons.

Answer 1

Put your MainClass in a specified package (instead of the default, nameless package as you have now) and import it in your JIFrame... classes.
package MyPackage
|
--> MainClass.java
.... |
.... --> package GuiFrames
.... .... |
.... .... --> JIFrameOne.java
so the source code looks like:
// MainClass.java
package MyPackage;
public class MainClass {
// JIFrameOne.java
package MyPackage.GuiFrames;
import MyPackage.MainClass;
public class JIFrameOne {
