Any class may be unloaded when none of it's instances and class objects that represent this class are reachable. (T/F?)



The answer is False.

my question is what does it mean by the term "unloaded", can anyone help clarify what it meant with the above statement.

This seems to be referring to class loaders. Class loaders, as far as I know, are not a topic on SCJP.

Where did you find this question?.

Here was the explanation to the statement above:

A class or interface may be unloaded if and only if its class loader is unreachable (the definition of unreachable is given in JLS 12.6.1). Classes loaded by the bootstrap loader are not unloaded.

I agree. Classloaders are NOT a part of SCJP and this question is off-topic here.
The poster might want to refer elsewhere.
