Why does this Java regex cause “illegal escape character” errors?

Question

I\'m working on a solution to a previous question, as best as I can, using regular expressions. My pattern is

\"\\d{4}\\w{3}(0[1-9]|[12][0-9]|3[01])([01][0-         


        

Answer 1

Did you try "\\d" and "\\w"?

-edit- Lol I posted the right answer and get down voted and then I notice that stackoverflow escapes backslashes so my answer appeared wrong :)
