如何使用JAVA 8检查一个对象的所有字段是否都为空？

import java.lang.reflect.Field;
import java.util.Arrays;

public class ObjectFieldChecker {
    public static boolean areAllFieldsEmpty(Object obj) {
        Field[] fields = obj.getClass().getDeclaredFields();
        return Arrays.stream(fields)
                .allMatch(field -> {
                    field.setAccessible(true);
                    try {
                        return field.get(obj) == null;
                    } catch (IllegalAccessException e) {
                        e.printStackTrace();
                        return false;
                    }
                });
    }
}

public class Person {
    private String name;
    private int age;
    private String address;
    
    // 省略构造方法和其他方法
    
    public static void main(String[] args) {
        Person person = new Person("John", 30, "123 Main St");
        boolean allFieldsEmpty = ObjectFieldChecker.areAllFieldsEmpty(person);
        System.out.println("All fields are empty: " + allFieldsEmpty);
    }
}
