This is from K&B book. Chapter 3.

Could you please explain how come f1.x==f3.x returns true, because f1.x prints 5 and f3.x prints 6.

Hi Cathymala:

Remember that when you are passing objects as arguments, you are passing it by reference, so in the FizzSwitch method, you have the x, and z Fizz variables are refering to the same object, so if you are modifying the values in z or even x, you also are modifying the values in f1. Check this printing the value of f1.x before the f1==f3 statement.

Regards,

Alejandro Galvan
