Controlling bad words in my app

Question

I have created an Android app wherein the users can give reviews and comments the products. Is there a way to control users from writing bad words in the reviews and comments or is there any sdk available for doing that.

Do it server side if you're using php and If you're just trying to do a simple word filter, create a single long regexp with all of the banned phrases that you want to censor, and merely do a regex find/replace with it. A regex like:

$filterRegex = "(boogers|snot|poop|shucks|argh|fudgecicles)"

and run it on your input string using preg_match() to wholesale test for a hit,

or preg_replace() to blank them out.

You have to create a class for the censor module, this is somewhat greedy in implementation.

public class WordFilter {

    static String[] words = {"bad", "words"};

    public static String censor(String input) {
        StringBuilder s = new StringBuilder(input);
        for (int i = 0; i < input.length(); i++) {
            for (String word : words) {
                try {
                    if (input.substring(i, word.length()+i).equalsIgnoreCase(word)) {
                        for (int j = i; j < i + word.length(); j++) {
                            s.setCharAt(j, '*');
                        }
                    }
                } catch (Exception e) {
                }
            }
        }
        return s.toString();
    }

    public static void main(String[] args) {
        System.out.println(censor("String with bad words"));
    }
}

The issue only is that this implementation is prone to clbuttic mistakes. — Joshua Dapitan, Mar 22 '16 at 12:50
