Which version runs for calc(5) when only long and double exist?
Short answer. The long version, because it is the closest widening.
What happens if two versions fit equally?
The call is ambiguous and the compiler reports an error.
Remember
| Exact match first |
| Then widening, then boxing |
| A tie is a compile error |
There is no int version. So what runs? Five is an int. Java tries an exact match first, then widening. Long is closer than double, so calc of long runs. Exact match first. Then widening, then boxing. A tie is an error.
