Modifier

[sandhi mridul]

Hi,

Please help me with this question from a mock exam.

Which modifier or modifiers should be used to denote a variable that should not be written out as part of its class' persistent state? (Choose the shortest possible answer.)

Options are:

1-private
2-protected
3-private protected
4-transient
5-private transient

As per me the answer should be private, but its transient.

I found diffrent diffrent answer for this question in diffrent mock test.
so confused.

Please help me with this.

Thanks
Sandhya

They refer to two very different concepts:

1. the class persistent state refers to the action of save the object (and its members) to a database. Which members should be saved (should be persisted) and which ones not (should not be persisted because they are in effect "transient").

2. the degree of access/visibility the class allows to the rest of the universe (other packages and or classes).

The question tests Exam objective 3.3 on Serialization. The answer is transient.

Guys,
What about 5. private transient..
it also seems to be a possible correct answer.
