JavaFX - 如何創(chuàng)建用戶對(duì)象(POJO)frp，bindable屬性

import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;

public class Main {
    public static void main(String[] args) {
        Student contact = new Student("FirstName", "LastName");

        fname.bindBidirectional(contact.firstNameProperty());

        lname.bindBidirectional(contact.lastNameProperty());

        System.out.println(fname.getValue() + " " + lname.getValue());
        System.out.println(contact.getFirstName() + " " + contact.getLastName());
        
        fname.setValue("new FirstName");
        lname.setValue("new LastName");

        System.out.println(fname.getValue() + " " + lname.getValue());
        System.out.println(contact.getFirstName() + " " + contact.getLastName());
    }
}
