A. True
B. False

Answer and Explanation (Click to expand)

Answer:

Explanation:

This will not compile because a short VARIABLE can NEVER be assigned to a char without explicit casting. A short CONSTANT can be assigned to a char only if the value fits into a char.
short s = 1; byte b = s; => this will also not compile because although value is small enough to be held by a byte but the Right Hand Side i.e. s is a variable and not a constant.
final short s = 1; byte b = s; => This is fine because s is a constant and the value fits into a byte.
final short s = 200; byte b = s; => This is invalid because although s is a constant but the value does not fit into a byte.
Implicit narrowing occurs only for byte, char, short, and int. Remember that it does not occur for long, float, or double. So, this will not compile: int i = 129L;
