Question

An expression involving byte, int, and literal numbers is promoted to which of these?

(a) int

(b) long

(c) byte

(d) float

The question was posed to me in examination.

This is a very interesting question from Integer and Floating Data Types topic in section Data Types, Variables and Arrays of Java

Answer 1

Right choice is (a) int

For explanation I would say: An expression involving bytes, ints, shorts, literal numbers, the entire expression is promoted to int before any calculation is done.
