无法使用反射访问受保护的属性

public class MyClass {
    protected String protectedField = "Protected Value";
}

import java.lang.reflect.Field;

public class ReflectionExample {
    public static void main(String[] args) {
        try {
            // 创建 MyClass 的实例
            MyClass obj = new MyClass();

            // 获取 protectedField 字段
            Field field = MyClass.class.getDeclaredField("protectedField");

            // 设置字段可访问
            field.setAccessible(true);

            // 获取字段的值
            String value = (String) field.get(obj);
            System.out.println("Original Value: " + value);

            // 修改字段的值
            field.set(obj, "New Value");
            value = (String) field.get(obj);
            System.out.println("Modified Value: " + value);
        } catch (NoSuchFieldException | IllegalAccessException e) {
            e.printStackTrace();
        }
    }
}

Original Value: Protected Value
Modified Value: New Value
