Doubt in implict conversion

[sakthi moorthy]

byte b = 1;
char c = 2;
c = b;//not allowed

but if i make
final byte b=1;
then it works reason?

The reason it cannot covert it without it being final is because your byte variable could be negative, which is out of bounds for a char. By making it final you are stating that "a" 100% for sure will be positive.

If you change it to

final byte b = -104;
char c = 2;
c = b;

It will still throw the error because it needs to know you are giving it a positive number.
