Hi, I just saw ur ques..hope till the time u will read this reply, u have given ur exam..so hope u have done well..
Here is the answers of ur questions...
When enum is declared inside the class in the same package, it needs to be imported explictly but if the enum is outside the class declaration, it does not need to be imported..its automatically available to ur class if it is in the same package...
Hope it helps,
