Erreur inhabituelle avec JavaFX ObservableList

Question

Je suis en train d'écrire une interface graphique pour un projet d'école et Layout Managers m'a énervé alors je suis passé à JavaFX. Je tente de remplir un TableView et TableColumns avec des exemples de données pour l'instant, mais je reçois une erreur étrange avec la liste Observable.

erreur comme suit:

Error:(84, 27) java: method addAll in interface javafx.collections.ObservableList<E> cannot be applied to given types; 
     required: javafx.scene.control.TableColumn<capture#1 of ?,?>[] 
     found: javafx.scene.control.TableColumn<Pizza,java.lang.String>,javafx.scene.control.TableColumn<Pizza,java.lang.String>,javafx.scene.control.TableColumn<Pizza,java.lang.String> 
     reason: varargs mismatch; javafx.scene.control.TableColumn<Pizza,java.lang.String> cannot be converted to javafx.scene.control.TableColumn<capture#1 of ?,?> 
Error:(85, 33) java: incompatible types: javafx.collections.ObservableList<Pizza> cannot be converted to javafx.collections.ObservableList<capture#2 of ?> 

Mon code actuel:

    } 

    public void tableStuff(){

     tableSize = new TableColumn<>(); 
     tablePrice = new TableColumn<>(); 
     tableSize.setCellValueFactory(new PropertyValueFactory<>("size")); 
     tableDesc.setCellValueFactory(new PropertyValueFactory<>("desc")); 
     tablePrice.setCellValueFactory(new PropertyValueFactory<>("Price")); 
     table = new TableView<>(); 
     table.getColumns().addAll(tableSize,tableDesc,tablePrice); 
     table.setItems(tableFill()); 
    } 

    public ObservableList<Pizza> tableFill() { //TODO: create input into pizzas 
     ObservableList<Pizza> pizzas = FXCollections.observableArrayList(); 
     //char size, Boolean cheese, Boolean pepperoni, Boolean olives, Boolean pineapple, Boolean tomatoes, Boolean mushrooms 
     pizzas.add(new Pizza("S", "Stuff", "$1.1 Mil.")); 
     pizzas.add(new Pizza("S", "Stuff", "$1.1 Mil.")); 
     return pizzas; 
    } 
}

Answer 1

private TableView<?> table; 

Remplacer ? avec le type exact des lignes de la table: Pizza.
