Best way to convert an ArrayList to a string

Answer 1

If you happen to be doing this on Android, there is a nice utility for this called TextUtils which has a .join(String delimiter, Iterable) method.

List list = new ArrayList();
list.add("Item 1");
list.add("Item 2");
String joined = TextUtils.join(", ", list);

Obviously not much use outside of Android, but figured I'd add it to this thread...
