Ok, I agree here.
Besides the scope of the question..
short s = 10;
it compiles ok..
10 is implicitly an int.
How does the compile do in order to accomplish the operation without causing an exception?
There is an implicit conversion like (short)10. or the compiler sees at compilation time that the number 10 can actually fit a short and therefore no problem?
What happens behind the scenes?
Thanks a lot in advance.

Underlining also the fact that:

Code: Select all

int a = 4;
short b = 10+a;

It gives a compilation error.

Cannot convert int to short: type mismatch.

Thanks in advance.
This software plush forum is immense.

This is because of implicit narrowing of compile time constant int value into a shorter type such as a byte or short. Check this out for more info: http://stackoverflow.com/questions/2720 ... nd-casting

I agree, you dont need to think about it.

2 answers are correct:

1 - false
2 - false
3 - true
4 - none

So of course only 1 and 2 can be the answers

But remember, that
final short s = 10;
char c = s; - will be fine work
