Stripping of unwanted characters from string

Hi Friend,

Try this:

public class StripCharacters {
   public String strip(String s) {  
    String st =" abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
    String result = "";
    for ( int i = 0; i < s.length(); i++ ) {
        if ( st.indexOf(s.charAt(i)) >= 0 )
           result += s.charAt(i);
        }
    return result;
    }
  public static void main(String args[]) {
     StripCharacters t = new StripCharacters();
     System.out.println(t.strip("Hello **%$#)(World>"));
     }
}

Thanks
