I was reading somewhere that even if I use int primitives, adding them to certain types of collections may result in a conversion from int to integers.
When is this the case?

Java collections can only contain objects. Therefore, all collections will Autobox any primitive types you pass them into their equivalent object (boxed) form before storing them. So
intprimitives will be converted toIntegers before being stored in a collection.
