OP asked how to populate a TableView, why are the answers talking about ListView? — Ojonugwa Jude Ochalifu

You must use a ObservableList as your datasource and to achieve this when you have a List you can use:

FXCollections.observableList(yourList);

If there is no model then you want to show only one column list. So after taking assumption of that your arraylist's object type is the wrapper class (of the primitive data types) like Integer, Double, String etc., you can use ListView instead of TableView.

List<Double> doubles = new ArrayList<Double>();
doubles.add(12.12d);
ObservableList<Double> names = FXCollections.observableArrayList(doubles);
ListView<Double> listView = new ListView<Double>(names);

@Rajesh. Just use dummy model and get rid of all low level API complexities. Or use multiple listviews.
