Answer 1

I don't like to use regex, so here is another simple solution.

public String removePunctuations(String s) {
    String res = "";
    for (Character c : s.toCharArray()) {
        if(Character.isLetterOrDigit(c))
            res += c;
    }
    return res;
}

Note: This will include both Letters and Digits
