What's the equivalent of addslashes() in JSP / Servlets?

Question

How to add slashes to a particular string in JSP? I want to convert this PHP code $subj = addslashes($_POST['txtsubjct']); to JSP.

Answer 1

addslashes() is not particularly needed:

If you want to protect from sql-injections, use PreparedStatement

Answer 2

public static String addSlashes(String s) {
    s = s.replaceAll("\\\\", "\\\\\\\\");
    s = s.replaceAll("\\n", "\\\\n");
    s = s.replaceAll("\\r", "\\\\r");
    s = s.replaceAll("\\00", "\\\\0");
    s = s.replaceAll("'", "\\\\'");
    return s;
}
