Help on object references understanding...

[Wee Keong Soh]

Hi,

class Dog {
Cat c = new Cat();
}

class Cat {
//blah blah blah
}

Dog d = new Dog();
Dog a;
a = d;

im aware that the Dog object will have 2 references refering to it. But how many references to Cat object will i have?

One !!!

Two references, both pointing to the same single object.

Hi,

So am i right to say that there will be 1 dog object with 2 references to it, and 1 cat object also with 2 references to it?

Thanks

No.

1) 1 Dog object with 2 references to it - correct
2) 1 Cat object with 2 references to it - wrong

The cat object has only 1 reference, that is the dog object.
