[FIXED] How to set default value in comboBox javafx?

Issue

I need to set a default value for a ComboBox from an ObservableArrayList, I am trying to set the first value in my ArrayList as a default value.

List = FXCollections.observableArrayList(arrayList);
comboBox.setItems(List);

Solution

comboBox.getSelectionModel().selectFirst();
