How come autoboxing doesn't work for Short(5)?

Question

How / why is is that autoboxing works for the first example below, but not the second? What's the reasoning / logic behind this?

Short i = 5; // works
Short i = new Short(5) // doesn't work

Short i = new Short( (short) 5) // works again, but uses explicit cast

Answer 1

As the javadoc indicates, there is no constructor in Short taking an int as argument. And 5 is an int.

Autoboxing is irrelevant. What would be needed for this to work is auto-narrowing.
