Entering data into TableView using setItems method

Question

I am trying to populate my javafx application TableView using setItems method, while doing so, i first defined my controller path, by doing

fx:"sample.Application"

then i defined my data model with the class name "Products" with all the necessary constructors and getters and setters. I then started writing my controller code, i defined all the necessary fx: id's with annotation of FXML, I override the initialize method which apparently is giving no errors, also to populate TableView i used ObserverList and called constructor of Products by using observerArrayList, in the end when i try to populate the TableView with fx:id ="table", by using setItems(), i got an error:

table.setItems(prodList);

error:

Error:(46, 19) java: identifier expected Error:(46, 28) java: identifier expected

here is the code:

FXML CODE:

<TableView fx:id="table" GridPane.columnIndex="0" GridPane.columnSpan="2" GridPane.halignment="LEFT" GridPane.rowIndex="3" >
        <columns>                                                                                                               
            <TableColumn fx:id="col_id" text="PRODUCT ID"/>                                                                     
            <TableColumn fx:id="col_name" text="NAME"/>                                                                         
            <TableColumn fx:id="col_price" text="PRICE" />                                                                      
            <TableColumn fx:id="col_tax" text="TAX" />                                                                          
            <TableColumn fx:id="col_discount" text="DISCOUNT" />                                                                
        </columns>                                                                                                              
</TableView>

Controller code

public class Application implements Initializable {
    @FXML
    private TableView<Products> table;
    @FXML
    private TableColumn<Products, Integer> col_id;
    @FXML
    private TableColumn<Products, String> col_name;
    @FXML
    private TableColumn<Products, Integer> col_price;
    @FXML
    private TableColumn<Products, Integer> col_tax;
    @FXML
    private TableColumn<Products, Integer> col_discount;

    final ObservableList<Products> prodList = FXCollections.observableArrayList(
            new Products(11, "Laptop", 25000, 23, 12 )
    );


    @Override
    public void initialize(URL location, ResourceBundle resources) {
        col_id.setCellValueFactory(new PropertyValueFactory<>("productId"));
        col_name.setCellValueFactory(new PropertyValueFactory<>("name"));
        col_price.setCellValueFactory(new PropertyValueFactory<>("price"));
        col_tax.setCellValueFactory(new PropertyValueFactory<>("tax"));
        col_discount.setCellValueFactory(new PropertyValueFactory<>("discount"));
    }

    table.setItems(prodList); //error
}

Answer 1

You haven't set the property value factory in the initialize method. I think that's causing the problem.

There's nothing inside the PropertyValueFactory<>. You have to set it the way given below -

    col_id.setCellValueFactory(new PropertyValueFactory<Products, Integer>("productId"));
    col_name.setCellValueFactory(new PropertyValueFactory<Products, String>("name"));
    col_price.setCellValueFactory(new PropertyValueFactory<Products, Integer>("price"));
    col_tax.setCellValueFactory(new PropertyValueFactory<Products, Integer>("tax"));
    col_discount.setCellValueFactory(new PropertyValueFactory<Products, Integer>("discount"));

Another thing, table.setItems(prodList) should be inside the initialize method. Correct it.
