public void process(int count) //line 1
{
for ( int i = 1; i < count; i++ ) //line 2
{
Object temp = new Object(); // line 3
}
// Line 4
}

My thinking was 5 objects are available for gc after line 4. 4 from temp and 1 from variable i.

your answer does to consider the scope for i, please clarify

variable i is a primitive type. They are not even objects. Primitives are never GCed.

I was thinking the same thing. Thanks for the clarification!

I think correct answer here is 0, because all the references are active and not nulled. Particularly if keep in mind that even if all references and references are nulled, its not a guarantee that gc will run...
