Weird java behavior with casts to primitive types

Question

This was probably asked somewhere but I couldn\'t find it. Could someone clarify why this code compiles and prints out 1?

long i = (byte) + (cha         


        

Answer 1

Unary operators and casting :)

+1 is legal

(byte) + 1 is casting +1 to a byte.

Sneaky! Made me think.
