如何检查List<Object>中Object的任何空字段？

import java.lang.reflect.Field;
import java.util.ArrayList;
import java.util.List;

public class ObjectFieldChecker {
    public static void main(String[] args) {
        List<Object> objectList = new ArrayList<>();
        objectList.add(new Person("John", 25));
        objectList.add(new Person("Jane", null));
        objectList.add(new Person(null, 30));

        for (Object obj : objectList) {
            checkObjectFields(obj);
        }
    }

    private static void checkObjectFields(Object obj) {
        Class<?> clazz = obj.getClass();
        Field[] fields = clazz.getDeclaredFields();

        for (Field field : fields) {
            field.setAccessible(true);
            try {
                Object value = field.get(obj);
                if (value == null) {
                    System.out.println("Empty field found: " + field.getName());
                    // 可以在这里进行相应的处理
                }
            } catch (IllegalAccessException e) {
                e.printStackTrace();
            }
        }
    }

    private static class Person {
        private String name;
        private Integer age;

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