I got the answer: It's very simple.
DateTimeFormatter fmt = DateTimeFormat.forPattern("MM/dd/yyyy");
String formattedDate = jodeLocalDateObj.toString( fmt );
LocalDate's toString
can take a format string directly, so you can skip creating the DateTimeFormatter:
String formattedDate = myLocalDate.toString("MM/dd/yyyy");
