Replace character in StringBuilder [duplicate]

Answer 1

Try this way

StringBuilder sb = new StringBuilder();
            sb.append("01-02-2013");

            sb.replace(sb.indexOf("-"), sb.indexOf("-")+1, "/") ;
            sb.replace(sb.indexOf("-"), sb.indexOf("-")+1, "/") ;
            System.out.println(sb.toString());

Better approch is

sb.toString().replaceAll("-", "/");
