Java Language Lists Making a list unmodifiable
Example
The Collections class provides a way to make a list unmodifiable:
List<String> ls = new ArrayList<String>();
List<String> unmodifiableList = Collections.unmodifiableList(ls);
If you want an unmodifiable list with one item you can use:
List<String> unmodifiableList = Collections.singletonList("Only string in the list");
