Answer 1

I'm good with REs, not expert, but good. I don't think that a single RE can do that. I think that four simple REs using character classes and testing whether or not there is a match would be my approach.

Answer 2

^[a-zA-Z].*[A-Z].*[0-9].*\D$ this is what i used but it checks their order of precedence, is there a way to make it check anywhere?

when i have a string " Lo2k" it gives me an error and I've spotted that it's looking for yet another Capital letter from the input.

Answer 3

I'm sorry, I can't get a working solution.
