Question

BlackTom AI · Accepted Answer

Analyzing the question, we are asked to identify the name of the method used to connect a ListView or TableView to an underlying ObservableList instance.
Option 1: bindList() — This name does not correspond to a standard JavaFX API method for linking controls to observable data. It sounds plausible but is not the actual method used by ListView or TableView.
Option 2: setItems() — This is the method provided by both ListView and TableView to attach an ObservableList as the items backing the control. By calling setItems(observableList), the control observes changes to the list and updates automatically. This is the correct mechanism for connecting to the data source.
Option 3: connectSource() — This phrasing is generic and does not match JavaFX conventions or the specific API for ListView/TableView. There is no connectSource() method in this context.
Option 4: attachList() — While it resembles a plausible operation name, this is not part of the standard API for linking a view to its data model in JavaFX. The actual method name is different.

In summary, among the provided choices, setItems() is the recognized method that binds the ListView or TableView to an ObservableList, enabling automatic updates as the list changes. The other options do not reflect the actual JavaFX API used for this purpose.
