This question has been done to death, and I would agree that enums are the way to go. However, I am curious as to how enums compile in the final code- #defines are just string replacements, but do enums add anything to the compiled binary? Or are they both equivalent at that stage. When writing firmware and memory is very limited, is there any advantage, no matter how small, to using #defines?

Thanks!

EDIT: As requested by the comment below, by embedded, I mean a digital camera.

Thanks for the answers! I am all for enums!

I've been trying for 3 hours and I just can't understand what is happening here. I have an enum 'Maze'. For some reason, when the method 'search' is called on this enum it's EXTREMELY slow (3 minutes to run).

Hi all, Just out of curiosity, asking this Like the expression one below a = (condition) ? x : y; // two outputs why can't we have an operator for enums? say, myValue = f ??? fnApple() : fnMango() : fnOrange(); // no. of outputs specified in the enum definition instead of switch statements… >>> More

I've switched from using constants for Strings: public static final String OPTION_1 = "OPTION_1"; ... to enums: public enum Options { OPTION_1; } With constants, you'd just refer to the constant: String s = TheClass.OPTION_1 But with Enums, you have to specify toString(): String… >>> More
