数组到组合框-JavaFx

我正在做一个学校的项目,我试图把一个字符串数组直接放入一个组合框中,结果发现一个错误。

错误:java:不兼容的类型:java。lang.String[]无法转换为javafx。收藏。观察者<JAVAlang.String>

ComboBox comboDecks;
ComboBox comboTrucks;
ComboBox comboWheels;
private final String[] deckArray = {"The Master Thrasher - $60 ", "The Dictator - $ 45", "The Street King - $ 50"};
private final String[] trucksArray = {"7.75-inch axle - $35 ", "8-inch axle - $40 ", "8.5-inch axle - $45 "};
private final String[] wheelsArray = {"51mm - $20", "55mm - $22", "58mm - $24", "61mm - $28"};


@Override
public void start(Stage stage) throws IOException {

    title1 = new Text("Skateboard Designer");
    title2 = new Text("Choose from the following Decks, Trucks, Wheels, and Accessories to design and price your own skateboard!");
    lblDecks = new Label("Decks: ");
    lblTrucks = new Label("Trucks: ");
    lblWheels = new Label("Wheels: ");
    lblAccess = new Label("Accessories: ");
    comboDecks = new ComboBox(deckArray);
    comboTrucks = new ComboBox(trucksArray);
    comboWheels = new ComboBox(wheelsArray);
