[SOLVED]a problem in regex

Question

I used replaceAll("[^\\w\\s]", ""] to remove everything except characters and white spaces but digits didn't remove
what's my mistake??
later I figured out that I can use [^a-zA-Z\\s] instead but I just wanted to know can I use the first syntax or no that's completely wrong for such thing.

Answer 1

\\w will include number and _
so \\w is kinda equal to [a-zA-Z_0-9]

Answer 2

I had the same problem as hamid

Answer 3

or
.replaceAll("[^\\p{Alpha}\\s]","");

Answer 4

Answer 5
