TextFiledEvent.class 

public class TextFiledEvent extends Application {

    @Override
    public void start(Stage primaryStage) {
        TerminalTextField btn = new TerminalTextField();
        VBox root = new VBox();
        root.getChildren().add(btn);

        Scene scene = new Scene(root, 300, 250);

        primaryStage.setTitle("Hello World!");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        launch(args);
    }

}

TerminalTextField.class

class TerminalTextField extends TextField {

    ArrayList<String> arrayList = new ArrayList<>();
    int sizeOfList = 10;
    int keyPoint;

    public TerminalTextField() {
        setField();
    }

    public TerminalTextField(String text) {
        super(text);
        setField();
    }

    private void setField() {
        setOnKeyReleased(new EventHandler<KeyEvent>() {

            @Override
            public void handle(KeyEvent event) {
                if (event.getCode().isLetterKey()) {
                    setText(getText().toString().toUpperCase());
                    positionCaret(getLength());
                }
            }
        });
    }

}

You can achieve this by setting the fx id in scene builder of the fxml file of the text field. This should get rid of the need for the "private void onKeyTyped (ActionEvent ee) {" Then in the initialize method in your control class for example MainControl you need to add the set on key pressed with the event handler
Here is an example of how that would look:

package application;

import java.net.URL;
import java.util.ResourceBundle;

import javafx.event.EventHandler;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.TextField;
import javafx.scene.input.KeyEvent;

public class MainControl implements Initializable {
@FXML
TextField text1;
public void initialize(URL arg0, ResourceBundle arg1) {// Initializes
                                                        // everything
    text1.setOnKeyPressed(new EventHandler<KeyEvent>() {// Keyboard                                             // commands
        public void handle(KeyEvent ke) {
            if (ke.getCode().toString().equalsIgnoreCase("ENTER")) {
            //do something

    }   
    }
    });



}
}

I hope that this helps
