Hierarchy of classes

If I have 3 classes, one instantiating the next, what would be the best way for the third class to access the first class. For example,

Code:

Class1:
public Class1(){
new Class2(this);
}
public String sayHello(){
return "hello";
}
 
Class2:
private final Class1 class1;
public Class2(Class1 class1){
this.class1 = class1;
new Class3(this);
}
 
Class3:
private final Class2 class2;
public Class3(Class2 class2){
this.class2 = class2;
[B]What's the most efficient way of accessing sayHello() from Class3?[/B]
}

 

Fl1pzta I believe this is the best method:

Code:

this.class2.class1.sayHell();

 

That's what I'm thinking, but is there any other way? Maybe better?

 

Pass the Class1 instance through to the Class3 instance? You can have more than one parameter on a constructor you know.
