Collections of what ? And how do you intend to separate each item ?

[Jesper de Jong]

Just call toString() on the collection.

List<Integer> list = new ArrayList<Integer>();
list.add(23);
list.add(12);
list.add(38);

String text = list.toString();
System.out.println(text);

Collections override toString method. It internally calls toString of Objects its holding. So if the objects its holding has overriden toString as required, then collection.toString should be what you actually want.
