Passing object refrences?

[Dillinger4]

Im working on a calculator(yes i am that bored) and im am trying to pass a refrence of the enclosing class to a constructor of another class. The object variable calculator is assigned a refrence to the class in the main method and is declared static. Any ideas why this fails to work? Thanks.

public class Calculator{
  static Calculator calculator; 
  public static void main(String[] args){calculator = new Calculator();}
}

public void addFunctionListeners(JButton[] functions){
    for(int i = 0; i < functions.length; ++i){
      functions[i].addActionListener(new FunctionListener(calculator)); // passing "this" will not work either    
   } 
  }

class FunctionListener implements ActionListener{
  Calculator calculator; 
  public void FunctionListener(Calculator calculator){
   this.calculator = calculator; 
  }
}

What's the exact error?

Ah i see it already. I do this alot and i should get out of the habit. The signature of the constructor is marked with void so the compiler treats it as a method.
