Problems javadoc inner classes...

Hi all,
I have a problems documenting an inner class. I've implemented it this way:
* In file TestClass.java I have an inner class "class MainClass" (this is the "upper" class of the file)
* MainClass instantiates a TestClass (which in the file is declared as an inner class within MainClass: "public class TestClass").
When I try to document it I get the following error message:
"No public or protected classes found to document."
What do I have to do? I'm using "Standard Doclet version 1.4.1" and why I have to use the inner class is a matter of saving a copy of the entire object, and I think this is the only solution to it, so what do I do?? Do I declare the "outer" class in a different way?
Very pleased for all help!!
Best regards,
Anjelica

* In file TestClass.java I have an inner class "class
MainClass" (this is the "upper" class of the file)
* MainClass instantiates a TestClass (which in the
file is declared as an inner class within MainClass:
"public class TestClass").So TestClass is an inner class of MainClass?? Then your file should be called MainClass.java.
Try if that helps.

Outer$Inner naming convention is not used by JVM to get declaring class.
You need to have proper InnerClasses attribute (refer to http://java.sun.com/docs/books/vmspec/2nd-edition/html/ClassFile.doc.html#79996)
in the generated classes. Did you check using jclasslib or another class file viewer and verified that your .class files have proper InnerClasses attribute?

Problem Compiling Inner Class

Can anyone tell me why the following won't compile?
Error : variable f might not have been initialized return f.getName();
     public void createNodes(File root, DefaultMutableTreeNode node)
          File [] files = root.listFiles();
          for(int counter = 0; counter < files.length; ++ counter)
               final File f = new File(files[counter].getPath())
                    public String toString()
                         return f.getName(); // Compiler error
                         //return ("ABC"); OKAY
               if(f.isDirectory())
                    DefaultMutableTreeNode dirNode = new DefaultMutableTreeNode(f.getName());
                    node.add(dirNode);
                    dirNode.setAllowsChildren(true); // HANDLE EMPTY DIRECTORIES
                    createNodes(f, dirNode);
               else
                    DefaultMutableTreeNode fileNode = new DefaultMutableTreeNode(f);
                    node.add(fileNode);
                    fileNode.setAllowsChildren(false);
     }

I had coded the thing like:
    for (int i = 0; i < files.length; i++) {
      final File f = new File(files[1].getPath()) {   // Yes that's a one in there
        public String toString() {
          return getName();
      System.out.println(f);
    }... Then passed into it a directory that contained a class named similar to an anonomous class name, and it just happened to be the 2nd file listed (files[1] that is) ... and therefore I got a whole bunch of that class name.class down the page instead of the entire contents of the directory ... and, oh well, threw me off ... like I said I think I need some sleep.

Why eclipse gives me warning if I access in inner class a parent field ?

I have a class
class A{
private Map fValues;
A(){
fValues= new HashMap();
prrotected class B {
B(){
fValues.get("String");
Above class is only for an example to expalin my problem.
Inner class B wants to access fValues from class A .
The eclipse gives me a warning
Access to enclosing method fValues from the type A is emulated by a synthetic accessor method. Increasing its visibility will improve your performance
I order to get rid of this warning I must make fValues public is this the only solution ?

Problem with final variables and inner classes

variables accessed by inner classes need to be final. Else it gives compilation error. Such clases work finw from prompt. But when I try to run such classes through webstart it gives me error/exception for those final variables being accessed from inner class.
Is there any solution to this?

Problem with final variables and inner classes (JDK1.1.8)

When using JDK1.1.8, I came up with following:
public class Outer
    protected final int i;
    protected Inner inner = null;
    public Outer(int value)
        i = value;
        inner = new Inner();
        inner.foo();
    protected class Inner
        public void foo()
            System.out.println(i);
}causing this:
Outer.java:6: Blank final variable 'i' may not have been initialized. It must be assigned a value in an initializer, or in every constructor.
public Outer(int value)
^
1 error
With JDK 1.3 this works just fine, as it does with 1.1.8 if
1) I don't use inner class, or
2) I assign the value in initializer, or
3) I leave the keyword final away.
and none of these is actually an option for me, neither using a newer JDK, if only there is another way to solve this.
Reasons why I am trying to do this:
1) I can't use a newer JDK
2) I want to be able to assign the variables value in constructor
3) I want to prevent anyone (including myself ;)) from changing the value in other parts of the class (yes, the code above is just to give you the idea, not the whole code)
4) I must be able to use inner classes
So, does anyone have a suggestion how to solve this problem of mine? Or can someone say that this is a JDK 1.1.8 feature, and that I just have to live with it? In that case, sticking to solution 3 is probably the best alternative here, at least for me (and hope that no-one will change the variables value). Or is it crappy planning..?

You cannot use a final field if you do not
initialize it at the time of declaration. So yes,
your design is invalid.Sorry if I am being a bit too stubborn or something. :) I am just honestly a bit puzzled, since... If I cannot use a final field in an aforementioned situation, why does following work? (JDK 1.3.1 on Linux)
public class Outer {
        protected final String str;
        public Outer(String paramStr) {
                str = paramStr;
                Inner in = new Inner();
                in.foo();
        public void foo() {
                System.out.println("Outer.foo(): " + str);
        public static void main( String args[] ) {
                String param = new String("This is test.");
                Outer outer = new Outer(param);
                outer.foo();
        protected class Inner {
                public void foo() {
                        System.out.println("Inner.foo(): " + str);
} producing the following:
[1:39] % javac Outer.java
[1:39] % java Outer
Inner.foo(): This is test.
Outer.foo(): This is test.
Is this then an "undocumented feature", working even though it shouldn't work?
However, I assume you could
get by with eliminating the final field and simply
passing the value directly to the Inner class's
constructor. if not, you'll have to rethink larger
aspects of your design.I guess this is the way it must be done.

Javadoc, generics and inner classes

I have implemented a generic class DiGraph with inner classes Vertex and Edge:
public class DiGraph<V,E> implements Iterable<DiGraph<V,E>.Vertex> {
   public Vertex addVertex(V value) {...}
   public Iterator<DiGraph<V,E>.Vertex> iterator() {... }
   public class Vertex implements Iterable<Edge> {
      V value;
   public class Edge {
      E value;
}When i run Javadoc it yields the following documentation of the class DiGraph :
public class DiGraph extends Object implements Iterable<DiGraph.Vertex>What I expected was
public class DiGraph extends Object implements Iterable<DiGraph<V,E>.Vertex>In a similar way the method addVertex appears as:
public DiGraph.Vertex addVertex(V value)instead of
public DiGraph<V,E>.Vertex addVertex(V value)This is very confusing, because if I create a graph
DiGraph<String,Integer> myGraph and the use e.g., the method addVertex I must write:
DiGraph<String,Integer>.Vertex v = myGraph.addVertex("a");Can anyone explain why the documentation lacks <V,E> ?

One more dumbshit question...
Is there a way to do this without the warnings OR the @SuppressWarnings({"unchecked"})
   * Returns the index of the last occurrence of the specified element in this
   * list, or -1 if this list does not contain the element.
//@SuppressWarnings({"unchecked"})
public int lastIndexOf(Object object) {
    int i = 0;
    int last = -1;
    for(Node<E> node=this.head.next; node!=null; node=node.next) {
      if (node.item.equals((E) object)) {
        last = i;
      i++;
    return(last);
produces the warning
C:\Java\home\src\linkedlist\LinkedList.java:313: warning: [unchecked] unchecked cast
found   : java.lang.Object
required: E
      if (node.item.equals((E) object)) {
                               ^... remembering that List specifies +public int lastIndexOf(Object object);+ as taking a raw Object, not E element, as I would have expected.
Thanx all. Keith.

See [http://forums.sun.com/thread.jspa?threadID=5333060&tstart=0]. In general, if you use third-party libraries in your code, you should include these libraries in Javadoc's classpath option when generating documentation.

Inner class problem

Hi.
I want 100 buttons to be displayed, 10 rows with 10 cols. To create all buttons I do a loop, and calls a function that creates and adds the buttons to the panel.
Here is the code sample.
<CODE>
// Here I adds the buttons
for (int i = 0; i < 10; i++) {
   for (int y = 0; y < 10; y++) {
      addButton(this, title,
      new ActionListener() {
         public void actionPerformed(ActionEvent e) {
            check(i,y);
      },i,y,1,1);
// The function to add buttons
public void addButton(Container c, String title, ActionListener a, int x, int y, int w, int h) {
buildConstraints(gbco,y,x,w,h,0.0,0.0);
JButton b = new JButton();
b.addActionListener(a);
b.setText(title);
b.setSize(40,40);
Insets s = new Insets(0,0,0,0);
b.setMargin(s);
c.add(b,gbco);
</CODE>
The problem is that I want to access i, y (loop variables - wich represents the cordinates: i = rows and y = cols) in the actionPerformed() function (when I call check(i,y). But I cant access them, cause they are accessed within an inner class, and in order to do that, I have to declare i,y final. Wich I obvious cant do since they increase every time they loop.
So any suggestions on how to do this in another way, or how to get around this problem(eg. displaying 100 buttons, and when I click one, it should know what cordinates it has)?

one (of many) ways to do that is to make your own class. It would look something kinda like this...
public class smartJButton
private JButton jb;
private int row;
private int column;
public smartJButton( int r, int col, JButton button )
jb = button;
jb.addActionListener(new java.awt.event.ActionListener()
   public void actionPerformed(java.awt.event.ActionEvent evt)
   { showCoordinates(); }
row = r;
column = col;
public void getCoordinates()
{ System.out.println("I am at row "+row+" and column "+column"); }
}

Deployment problem: Inner class not included

Hi, All:
I am trying to deploy my Java application using JDeveloper 3.2. I was be able to successfully deployed it when I first designed the project, even some of the files also have inner classes. Now I have added some new inner classes to a public class and tried to re-deploy it. However how hard I tried (I have tried to rebuild the project, redefine the depoyment profile, even tried to add these class files directly through the advanced tab), the newly added inner class will not be able to be added to the deployed Jar file. I have checked the class files under myclass directory, and found all the inner class files are there, and I can run the application in JDeveloper without any problem. I wonder if there is any tricks to solve this problem. (Other than use the jar command).
Thanks,
Peter

Also, it's probably a good idea to name your packages different than your classesMoreover, common naming conventions dictate you should never even use capitals in your package names if I'm not mistaken. Whereas class names should always at least begin with a capital.
This will help prevent a lot of confusion, both for the developer and the IDE. ;-)

EJB fails to compile - static inner class problem

I am using OC4J 9.0.4 and Sun JDK1.4.2 and EJBs fail to compile if they reference objects that contain static inner classes. However, they successfully compile under JDK1.4.1.
For example, I have a class like below:
public class ValueObject
public static class Key
private Key key;
private String value;
Any references to ValueObject.Key inside the EJB cause the EJB compiler to generate "ValueObject$Key" which is incorrect. JDK1.4.1 is more lenient than 1.4.2, and allows this error through.
Is there a way around this problem other than reverting to JDK1.4.1?
Regards,
Andy

The reason I don't want to move to JDK 1.4.1 is because of the memory leak in the StringBuffer.toString() method.
Is there anywhere I can submit this as a bug?
Regards,
Andy

Program Design Problem: Inner Class use verse interacting seperate classes?

i am designing a GUI based program that needs to have 2+ windows that interact with each other. In my original design there were just two windows: the World display, and the tile choser (this is for 2D map editing). Because there were only 2, I made them both inner classes of another class. The top level class's fields were how I got the two windows to interact.
Now I am adding more tile choser esque windows and it is getting very confusing and the amount of Fields is getting ridiculous and the whole thing isnt very OO.
I thought about splitting up the World Display window and the Tile Choser window into two different classes and just have multiple instances of the Tile Choser class for the additional windows.
The problem is the interaction. I could pass all of the variables that both classes require to constructers and set up lots and lots of get and set methods, but then that seems to destroy the whole idea of two classes. The whole project is getting really messy.
Any thoughts?
I know that was a jarbled explanation so just ask about any part that might be unclear

Create an object that represents the state being manipulated. The model.
Create methods to modify that data. Not getters/setters, but controllers. If it's a map, then maybe a method would be "addTown" or something. This represents the controller.
Create methods to render the data graphically. The views.
Pass this object to GUI widgets, or reference it from inner event handlers.

Problem with Outer and Inner Classes....or better way?

Right now I'm trying to create an Inner class.
My .java file compiles ok, and I create my jar file too.
But when I try to instantiate the Inner class, it fails:
java.lang.NoClassDefFoundError: com/myco/vlXML/vlXML$vlDocument.
Here's the class code:
public class vlXML{
    private ArrayList myDocList=new ArrayList(); //holds documents
    public vlXML(){
    private class vlDocument{
        public vlDocument(){
        //stuff goes here
    public vlDocument vlDOC(){
        return new vlDocument();
    public void addDocument(){
        vlXML xxx=new vlXML();
        vlDocument myDoc=xxx.vlDOC();
        myDocList.add(myDoc);
    public int getNumDocs(){
        return myDocList.size();
}Then, from a jsp page, I call:
vlXML junk1=new vlXML();
junk1.addDocument();...and get the error...
Can someone help me figure out why it's failing?
Thanks....

You nailed it - thanks....(duh!)
While I have your attention, if you don't mind, I have another question.
I'm creating a Class (outer) that allows my users to write a specific XML file (according to my own schema).
Within the XML file, they can have multiple instances of certain tags, like "Document". "Document"s can have multiple fields.
Since I don't know how many "Documents" they may want, I was planning on using an Inner Class of "Document", and then simply letting them "add" as many as necessary (thus the original code posted here).
Does that seem like an efficient (logical/reasonable) methodology,
or is there there something better?
Thanks Again...

Problems javadoc inner classes...
