The best practice depends on your needs. If you need to have a null value, then declare your method with the wrapper, otherwise use a primitive.

I liked this post very much and felt it was very informing, and I just want to try and understand unboxing/boxing correctly.

Does boxing happen when you parse a primitive to a method?

ex. someMethod(int value){}

I’m just trying to figure out which is the best practice when creating methods/constructor, using primitives or wrapped primitives?

ex. MyClass(Integer id, Long value){}

vs.

ex. MyClass(int id, long value){}

Hmm not sure I formulated my question correctly, but alas english is not my native tongue, so bare with me.
