Tell us what the output is, and what you do or do not understand about it.

The first "true" stems from the fact that f1 and f3 point to the same object (FizzSwitch returns the reference to f1, which then gets assigned to f3). Since "==" compares object references, they are equal. And since they point to the same object, naturally their "x" field is the same.
