如何从父类中获取子类的属性值？

class Parent {
    private String name;

    public Parent(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }
}

class Child extends Parent {
    private int age;

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

    public int getAge() {
        return age;
    }
}

public class Main {
    public static void main(String[] args) {
        Child child = new Child("Alice", 10);
        System.out.println(child.getName()); // 通过继承父类的getter方法获取属性值
        System.out.println(child.getAge());

        // 使用反射机制获取属性值
        try {
            Class<?> childClass = child.getClass();
            java.lang.reflect.Field ageField = childClass.getDeclaredField("age");
            ageField.setAccessible(true);
            int ageValue = (int) ageField.get(child);
            System.out.println(ageValue);
        } catch (NoSuchFieldException | IllegalAccessException e) {
            e.printStackTrace();
        }
    }
}
