Adding element to Set (not last and not first)
I'm a beginner, so please help me.
Set mySet= new HashSet();
(Let's assume, that here the set has already 20 elements)
How could i add myClass to mySet on the 7th position?
What would be the easiest way?
The Set must be here.
I don't think you want to use a Set for whatever you're trying to do. Instead, look at ArrayList
