以下是我到目前为止的说明和代码。我不确定我哪里出错了，但我知道我的循环不对。你能帮帮我吗？在一个新的 Java 文件中，使用规范文档作为指南创建 Monkey 类。Monkey 类必须执行以下操作： 从 RescueAnimal 类继承。实现所有属性以满足规范。包括一个构造函数。您可以使用默认构造函数。要在此标准上获得“模范”评分，您必须包含更详细的构造函数，该构造函数获取属性的所有值并设置它们。示例请参阅 Dog 类中的构造函数。包括所有实现属性的访问器和修改器。
在 Driver.java 类中，修改 main 方法。在 main() 中，您必须创建一个执行以下操作的菜单循环： 通过调用 displayMenu 方法显示菜单。此方法位于 Driver.java 类中。提示用户输入 根据用户输入的值采取适当的行动
