calling a function in a class's “owner” class

Question

Following pseudocode sums up my question pretty well I think...

class Owner {
    Bar b = new Bar();

    dostuff(){...}
}    

class Bar {
    Bar() {
              


        

Answer 1

class Owner {

    Bar b = new Bar(this);

    dostuff(){...}
}    

class Bar {
    Bar(Owner owner) {
       owner.doStuff();
    }
}

Answer 2

I think the way you have written the code, it is not possible to do. But if you declare Bar as inner class of Owner, you might get a closer solution.
