How do I refer to an array in a seperate class?

Hi,

I am defining a class as an array of objects:

MyClass [] myCass = new MyCass[9];

class MyClass{
void parameters(GLOBAL world){
}
}

Inside the class called GLOBAL, how do I then refer to the array of objects that are in MyClass? This doesn't work:

GLOBAL world;

class GLOBAL {
void main(MyClass[] myClass[]) {

}
}

I would advise against calling Global "GLOBAL". All capitals are traditionally used for constants - things that don't change. You risk confusing people who are reading your code.

I assume it's a typo that you want the array of objects in MyClass.

Here's how to do it:
Code:


MyClass [] myClass = new MyClass[9];
Global world;

void setup(){
  world = new Global();
  world.main(myClass);
}

class MyClass{
  MyClass(){
  }
}

class Global{
  Global(){
  }
  void main(MyClass [] reference){
    // Either access the array by passing a reference
    println(reference.length);
    // Or: myClass is a global variable, accessible to the whole applet
    println(myClass.length);
  }
}
