This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
My Java Cert book states this... For unary operators, if the operand is a byte, short or char, it is converted to an in (unless the op is ++ or --) The unary operators are +, -, ++, --, ~ So given this look at the following code byte a = 100; byte b = +a; This will flag an error due to the casting that needs to take place. It should look like this. byte a = 100; byte b = (byte)+a; This this correct?? -Dale

Yes, it is correct! As you said yourself, you have to explicitly cast it because Java promotes a literal to int when you use + or - before it. It is similar to the binary +, -, *, / etc... I suppose you've tried it out already... Hidy hooo! /Kaspar
