我坚持将数据从我的“Person.java”填充到TableView.

我将问题追溯到部分< Person firstName =“Jacob”lastName =“Smith”email =“jacob.smith@example.com”/>在最底部的“fxmltableview.fxml”文件中.

因此,似乎由于某种原因,我的“observableArrayList”并不是全部包含“Person.java”对象.允许使用“String.java”.
因为我在教程中逐字逐句阅读,并且我没有看到我的文件之间有任何差异,因此我没有对文件进行任务的想法.每当我删除< Person someStuff />它工作正常.

我该如何摆脱这个恼人的错误？

引发者：javafx.fxml.LoadException：Person不是有效类型.

“Person.java”是从教程中复制/粘贴的,这就是为什么我很沮丧,以至于它对我不起作用.无论如何,我会把它贴在这里.

package application;

import javafx.beans.property.SimpleStringProperty;

public class Person {
  private final SimpleStringProperty firstName = new SimpleStringProperty("");
  private final SimpleStringProperty lastName = new SimpleStringProperty("");
  private final SimpleStringProperty email = new SimpleStringProperty("");

  public Person() {
    this("","","");
  }

  public Person(String firstName,String lastName,String email) {
    setFirstName(firstName);
    setLastName(lastName);
    setEmail(email);
  }

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

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

  public String getLastName() {
    return lastName.get();
  }

  public void setLastName(String fName) {
    lastName.set(fName);
  }

  public String getEmail() {
    return email.get();
  }

  public void setEmail(String fName) {
    email.set(fName);
  }
}
