About Question enthuware.ocajp.i.v7.2.884 :

This Question is not quite clear ...
By "What can be inserted at // 1,"and by the answer "obj.name = null; as well as obj = null;" I unterstand there can be inserted "obj.name = null" as well as there can be inserted "obj = null;"

No, as the explanation says, obj.name = null; is not required to make obj eligible to be garbage collected.
You only need obj = null;
obj.name = null; will not make obj eligible to be garbage collected.

The question is to pick one answer that makes the object eligible for garbage collection. There are two such options that achieve this, even if the second includes some irrelevant code.

imo, it's poorly worded because the fifth answer is not incorrect.

[admin]

You may find such options in the real exam also. You need to pick the best answer.

I didn't quite understood this question, from what i recall an object is elegible for garbage collection once there are no more references pointing to it, or all of those references are out of scope. So, from my understanding both "obj.name = null; as well as obj = null;" make this condition true, therefore it looks the more righteous answer since it addresses both scenarios.

Please see response above.

i agree the question is not clear enough, i'm not mad at entuwearEnthuware but at Oracle, it's not good enough for them to make a very difficult language ... they need to make questions as much as ambiguous possible in extra... poor consideration for the devs working with their language
