Hi all ,
Extract from Khaled Mughal:-
Implicit Narrowing conversions can occur when :-
1. The source is a constant expression of either byte,short,char or int .
2. The target type is either byte, short or char .
3. The value of the source is determined to be in the range of the target type at compile time .

Now in accordance to the above rules:-
int i2=-20; (1)
final int i3=i2; (2)
final int i4=200; (3)
short s3=(short) i2; (4)
char c3=(char) i3; (5)

(4) gives compiler error . I cant understand why ?

Ragi, do you mean to ask without the explicit cast why is it failing?? because the above code compiles fine with the cast in place?

Please correct the indicated error in your question. And have a look on the JLS.
