How to populate comboBox

I have an FXML file which have a combo box which i want to populate in initialize() method in controller

Controller class:

@FXML
private ComboBox<String> comboBox;

void initialize()
{
    comboBox.addItem("123");
}

Whenever i want to complie i've got an error:

"The method addItem(String) is undefined for the type ComboBox<String>"

After reading lecture from oracle i've got the information, that combo box works for Objects, which String is, isnt it ?

What can be wrong?

You need to use setItems(ObservableList<T>).

addItem isn't a method declared for ComboBox. Check out the docs.

You can add items by creating an observable list, then passing it to setItems:

comboBox.setItems(FXCollections.observableArrayList("123"))

Or you can pass the ComboBox the list of items via it's constructor.
