Replacing ' char in a string

Question

How can I add a \(backslash) before before a '(apostrophe) in a String ?
I've been tryin' myString.replaceAll("'","\'") and myStringBuffer.deleteCharAt & insert but with no success

Answer 1

sorry... i don't read the API before answering u ;) replaceAll related to regex n it's new for me... it's alredy 11:15 PM, i'm going to sleep (i don't want to learn about regex for now)...
here is other solution:
public class ItsWork {
     public static String insertBefore(String original, String add, String before) {
          StringBuffer sb = new StringBuffer();
          int i = 0;
          do {
               i = original.indexOf(before);
               if (i != -1) {
                    sb.append(original.substring(0, i));
                    sb.append(add);
                    sb.append(before);
                    original = original.substring(i + 1, original.length());
               } else break;
          } while (true);
          sb.append(original);
          return sb.toString();
     public static void main(String[] args) {
          String myString = "do this realy don't work?";
          System.out.println(myString);
          myString = insertBefore(myString, "\\", "\'");
          System.out.println(myString);
}
