如何使用mapToDouble将多个对象字段从一个ArrayList“流式”传输到一个双精度数组？

import java.util.ArrayList;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        // 创建一个包含多个对象的ArrayList
        List<Person> personList = new ArrayList<>();
        personList.add(new Person("Alice", 25, 165.5));
        personList.add(new Person("Bob", 30, 180.0));
        personList.add(new Person("Charlie", 35, 175.2));

        // 使用mapToDouble方法将多个对象字段传输到一个双精度数组
        double[] heights = personList.stream()
                .mapToDouble(Person::getHeight)
                .toArray();

        // 打印双精度数组
        for (double height : heights) {
            System.out.println(height);
        }
    }

    static class Person {
        private String name;
        private int age;
        private double height;

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

        public double getHeight() {
            return height;
        }
    }
}
