In my Program i have to change the color of a sample string by clicking on the radio Buttons. But i keep getting errors every time i click on them. i keep getting this error. I am also using e(fx)clipse to code this.

Caused by: java.lang.ClassCastException:
javafx.graphics@10.0.2/javafx.scene.paint.Color cannot be cast to
javafx.graphics@10.0.2/javafx.scene.text.Text at
employee.view.MainController.colorRadioButtonSelected(MainController.java:83)

public class MainController {



    @FXML

    private BorderPane myPane;



    @FXML

    private RadioButton blackRadioButton;



    @FXML

    private ToggleGroup colorToggleGroup;



    @FXML

    @FXML

    private CheckBox boldCheckBox;



    @FXML

    private CheckBox italicCheckBox;



    String Text;

    Text sample=new Text(50,300,"SAMPLE");

    FontWeight weight = FontWeight.NORMAL;            //   FontWeight.BOLD is boldface

    FontPosture posture = FontPosture.REGULAR;       //    FontPosture.ITALIC is italic

    int size=18;

    boolean fontBold = false;

    boolean fontItalic = false;



    public void initialize() {

        blackRadioButton.setUserData(Color.BLACK);

        redRadioButton.setUserData(Color.RED);

        greenRadioButton.setUserData(Color.GREEN);

        blueRadioButton.setUserData(Color.BLUE);

        myPane.getChildren( ).add( sample );

        sample.setFont(Font.font("Verdana", weight, posture, size));     

    }   



    @FXML

    void boldCheckBoxSelected(ActionEvent event) {

    }



    @FXML

    void colorRadioButtonSelected(ActionEvent event) {

        sample= (javafx.scene.text.Text) colorToggleGroup.getSelectedToggle().getUserData();

    }



    @FXML

    void italicCheckBoxSelected(ActionEvent event) {

    }

}

You set the data as Color

blackRadioButton.setUserData(Color.BLACK);

redRadioButton.setUserData(Color.RED);

greenRadioButton.setUserData(Color.GREEN);

blueRadioButton.setUserData(Color.BLUE);

But you try to cast it as Text

(javafx.scene.text.Text) colorToggleGroup.getSelectedToggle().getUserData();

To fix this you can use a switch statement or multiple if statements to set sample object depending on which colour is selected. Example if statement:

if ((Color) colorToggleGroup.getSelectedToggle().getUserData() == Color.BLUE) {

    sample = new Text(50, 300, "Something");

}

Alternatively you can set the data for the radio buttons as Text, for example:

blueRadioButton.setUserData(new Text(50, 300, "Something"));
