如何使用javaFX在TreeView中插入多个不同的对象(类)

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TreeItem;
import javafx.scene.control.TreeView;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class TreeViewExample extends Application {
    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage primaryStage) {
        // 创建TreeView和根节点
        TreeView<String> treeView = new TreeView<>();
        TreeItem<String> rootItem = new TreeItem<>("Root");
        treeView.setRoot(rootItem);

        // 创建不同类型的对象
        Person person1 = new Person("John", 25);
        Animal animal1 = new Animal("Cat", "Meow");
        Animal animal2 = new Animal("Dog", "Woof");

        // 创建对应的TreeItem对象
        TreeItem<String> personItem = new TreeItem<>("Person: " + person1.getName());
        personItem.setValue(person1);
        TreeItem<String> animal1Item = new TreeItem<>("Animal: " + animal1.getName());
        animal1Item.setValue(animal1);
        TreeItem<String> animal2Item = new TreeItem<>("Animal: " + animal2.getName());
        animal2Item.setValue(animal2);

        // 插入子节点
        rootItem.getChildren().addAll(personItem, animal1Item, animal2Item);

        // 创建布局并将TreeView添加到其中
        VBox vbox = new VBox(treeView);

        // 创建场景并设置到舞台
        Scene scene = new Scene(vbox, 400, 300);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    // 示例对象：Person类
    private static class Person {
        private String name;
        private int age;

        public Person(String name, int age) {
            this.name = name;
            this.age = age;
        }

        public String getName() {
            return name;
        }

        public int getAge() {
            return age;
        }
    }

    // 示例对象：Animal类
    private static class Animal {
        private String name;
        private String sound;

        public Animal(String name, String sound) {
            this.name = name;
            this.sound = sound;
        }

        public String getName() {
            return name;
        }

        public String getSound() {
            return sound;
        }
    }
}
