Some questions about packages.

[sunde887]

I am working on a text editor and it's starting to become a decent amount of files and I would like to organize them better.

So far I have a source file which is the actual text editor, which handles all saving and font changing. The file uses actions which I would like to store in a folder.

For example I have

public class SaveAction extends AbstractAction{}
public class OpenAction extends AbstractAction()

there are 12 action classes in total. I would like to store them in a path of

c:/javacode/texteditor/actions

I packaged them all like this

package texteditor.actions;

I would have the actual text editor in the the path of

c:/javacode/texteditor

and packaged with

package texteditor;

My classpath points to the javacode directory.

Here is where I am running into trouble. All the actions have an instance of a text editor and the text editor has an instance of the actions. When I try to compile any of the code I get errors for all the instances of the other class. When compiling the actions I get errors for the text editor references, when compiling the texteditor I get errors for every reference to any action.

It seems like it's a circular problem where each file relies on the other being already compiled.

Any way to do this? I hope I am making myself clear.

Finally, if I can compile the code, does it matter where the class files need to be stored? Or can they be anywhere that the classpath can get access to?

Thanks for any help guys.

no, as long as all packages/classes are in the same project-root you can use any class in any package, but you must either import the classes you want to use or you must use the full package path when you use the class.

Thanks for that. As for my other question, here is an example of what I am having trouble with.

This is in the directory

c:/javacode/test

package test;

import test.package1.*;

public class A{
	private B x = new B(this);
}

and then b is in the directory

c:/javacode/test/package1

package test.package1;

import test.*;

public class B{
	private A x;
	public B(A x){
		this.x = x;
	}
}

errors when attempting to compile A

a.java:3: package test.package1 does not exist
import test.package1.*;
^
a.java:6: cannot find symbol
symbol  : class B
location: class test.A
        private B x = new B(this);
                ^
a.java:6: cannot find symbol
symbol  : class B
location: class test.A
        private B x = new B(this);
                          ^
3 errors

When I compile b

C:\Javacode\Test\Package1>javac b.java
b.java:6: cannot find symbol
symbol  : class A
location: class test.package1.B
        private A x;
                ^
b.java:7: cannot find symbol
symbol  : class A
location: class test.package1.B
        public B(A x){
                 ^
2 errors

Is the Test directory capitalized?

[sunde887]

Wow, I love you Fubar, when I read online it said to make package names lowercase so I assumed, and clearly made an ass of myself. Thanks very much for the help you guys.

glad you've got it working.
