nested objects in processing OOP

hi
I was trying to nest object in object, both of them belong to the same class, and one of arguments in constructor are this object dataType. Some example code below:
Code:
class Node{
Node a,b,parent;
float xdir;
void Node(Node _parent,float xDir){
parent=_parent;
xdir=xDir;
}
private void xclone(){ // two nested objects
a=new Node(this,1);
b=new Node(this,-1);
}
}
|

I this case, I've got message: "Perhaps you wanted the overloaded version "Node()"... interesting?
For example in Flash AS2 this kind of coding is possible.

q: why do you need to have "void" in your constructor?

actually, ive found that if you have a void before your contructer then it doesnt act as a contructer
also, what is htere at the moment will give you infinite amounts of nesting, which p5 probaly wont like...

constructors must have no return type in their declaration. otherwise it isn't handled as an constructor.
So, when you try to create a new object from your class with Node(), java looks for a constructor with this name, but cannot find one. But it finds a method
called Node(). That might be the reason for the message of the "compiler".

thank you very much, it's strange to me coding in processing (relative to flash, PHP, or JS).
Mythmon - don't worry about infinity nesting, see in my example.

forgive me, its my first code in processing
