Can I can create public static final variables in an interface? Can I keep some common constant values defined in these files?
Yes, you can:
However, it’s generally reckoned not to be a good idea these days. It’s not so bad if the interface has a real purpose as well, and the constants are likely to be used by most of the implementations… but introducing an interface just to make it easier to get to constants is an abuse of the purpose of interfaces, really. (And that’s what used to happen a lot.)
