我正在尝试使用 arrayList 填充 TableView。我有一个名为“personArray”的数组列表，它填充在名为 Person 的类中。该数组包含元素类型、姓名、性别、年龄、种族、出生日期、地址、声明、伤害和防御。使用断点我可以看到在创建表之前数组已正确填充。然后将数组列表转换为可观察列表“人员”。

下面的代码然后创建表。代码应该从可观察列表“人”中获取值并填充表，但它没有。该表保持空白。我尝试了许多不同的解决方案，但没有任何效果。

    TableView<Person> peopleTable = new TableView<Person>();
    ObservableList<Person> people = FXCollections.observableArrayList(personArray);

    TableColumn<Person, String> typeCol = new TableColumn<Person, String>("Type");
    typeCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("type")
        );

    TableColumn<Person, String> nameCol = new  TableColumn<Person, String>("Name");
    nameCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("name"));

    TableColumn<Person, String> genderCol = new  TableColumn<Person, String>("Gender");
    genderCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("gender")
        );

    TableColumn<Person, String> ageCol = new  TableColumn<Person, String>("Age");
    ageCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("age")
        );

    TableColumn<Person, String> ethnicityCol = new TableColumn<Person, String>("Ethnicity");
    ethnicityCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("ethnicity")
        );

    TableColumn<Person, String> dobCol = new  TableColumn<Person, String>("Date of Birth");
    dobCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("dob")
        );

    TableColumn<Person, String> addressCol = new  TableColumn<Person, String>("Address");
    addressCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("address")
        );

    TableColumn<Person, String> statementCol = new  TableColumn<Person, String>("Statement");
    statementCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("statement")
        );

    TableColumn<Person, String> harmCol = new  TableColumn<Person, String>("Harm");
    harmCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("harm")
        );

    TableColumn<Person, String> defenceCol = new TableColumn<Person, String>("Defence");
    defenceCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("defence")
        );


    peopleTable.getColumns().addAll(typeCol, nameCol, genderCol, ageCol, ethnicityCol, dobCol, addressCol,
            statementCol, harmCol, defenceCol);

    peopleTable.setItems(people);

我是 Java 新手，所以我不知道该怎么办？

编辑：

这是我的 Person 类（不包括创建新人员并将其放置在 personArray 中的 create 方法，因为它可以正常工作）。

public class Person {

protected static ArrayList<Person> personArray = new ArrayList<Person>();

protected enum personType {
    Suspect("Suspect"), Victim("Victim"), Witness("Witness");

    private String typeName;

    personType(String typeName) {
       this.typeName = typeName;
    }

   public String toString() {
    return this.typeName;
   }
}

protected enum genderType {
    Male("Male"), Female("Female");

    private String genderName;

    genderType(String genderName) {
       this.genderName = genderName;
    }

   public String toString() {
    return this.genderName;
   }
}

protected enum ethnicityType {
    White("White"), Black("Black"), Asian("Asian"), Indian("Indian");

    private String ethnicityName;

    ethnicityType(String ethnicityName) {
       this.ethnicityName = ethnicityName;
    }

   public String toString() {
    return this.ethnicityName;
   }
}

protected personType type;
protected String name;
protected genderType gender;
protected int age;
protected ethnicityType ethnicity;
protected LocalDate dob;
protected String address;
protected String statement;
protected String harm;
protected String defence;

protected Person(personType getType, String getName, genderType getGender, int getAge,
        ethnicityType getEthnicity, LocalDate getDob, String getAddress, String getStatement, String getHarm, String getDefence) {

    type = getType;
    name = getName;
    age = getAge;
    gender = getGender;
    ethnicity = getEthnicity;
    dob = getDob;
    address = getAddress;
    statement = getStatement;
    harm = getHarm;
    defence = getDefence;
}
}

这个对吗？因为还是不行
