Question

我尝试用Contacts填充TableView。我检查了typos（get and set），因为它已被java机器验证为实现列，但没有任何变化，我仍然具有相同的数据反射率错误

主类

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class Main extends Application {

@Override
public void start(Stage primaryStage) throws Exception{
    Parent root = 
    FXMLLoader.load(getClass().getResource("contactsScene.fxml"));
    primaryStage.setTitle("Contact World");
    primaryStage.setScene(new Scene(root, 700, 500));
    primaryStage.show();
}


public static void main(String[] args) {
    launch(args);
    }
}

public class Contact {
    public SimpleStringProperty firstName;
    public SimpleStringProperty lastName;
    public SimpleStringProperty number;


    public Contact(String firstName, String lastName, String number) {
        this.firstName = new SimpleStringProperty(firstName);
        this.lastName = new SimpleStringProperty(lastName);
        this.number = new SimpleStringProperty(number);


    }

    public String getFirstName() {
        return firstName.get();
    }

    public SimpleStringProperty firstNameProperty() {return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName.set(firstName);
    }
 }
