Javarules Roundup #125

[dennis zined]

hi all. just took javarules roundup and....
Question states: Can you automatically/implicitly convert a char to a short?
Answer given is no. They're the same bit-depth but since chars are unsigned, they might have a higher positive value than a short can accept.
Comment: I can automatically / implicitly convert a char to a short if the char variable is declared final and value not more than short's allowable maximum value. The code below when placed in a method and class compiles just fine.

        final char c2 = 3;
        short s2 = c2;  

Am i not reading the question right?

I think the question reffers implicitly to variables...
when you decared final char ...
you are dealing with a constant so not a variable but a value so its known at compile time) thats why u don't get a compile error
(value 3 is OK wihin range)
to better understand try the values 32767 (compiles since is last valid value for short) and 32768 (error) with you final char definition
