In this example you've not copied the Student object, so I think saying "passing a copy of the value also changes the real value of the object" is misleading. The thing that you are copying, and passing-by-value, is the reference to the object. The object stays living on the heap, and there's just one of them. That's why when you use the new reference to mutate the object, you're mutating it for everyone else that has a reference to the object. There's only one object. When the argument of the function is a primitive type, not a reference to an object, it is also copied.
