Hi

I want to remove characters from a string other then a-z, and A-Z. Created following function for the same and it works fine.

public String stripGarbage(String s) {
 String good = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz";
 String result = "";
 for (int i = 0; i < s.length(); i++) {
     if (good.indexOf(s.charAt(i)) >= 0) {
             result += s.charAt(i);
      }
   }
 return result;
}

Can anyone tell me a better way to achieve the same. Probably regex may be better option.

Regards

Harry
