That is the purpose of the generic declaration TreeSet<test>. You specify that the TreeSet is going to hold test objects.

Oh! ... got it. It was a general question about generics. I was mixing it with program behaviour.

Thanks Keith

Is the use of the Comparator interface allowed? As far as i know, only interface Comparable can be used.

Do you mean in general or with generics?

I meant the other options were related to the program behaviour whereas the last option was about the correct meaning of the "generic collection declaration", nothing related to program behaviour.
