JAVA基础编程跟constructors有关

完成以下编程要求

您必须实现以下类：
请记住，对于所有类，您必须添加：
构造函数
二传手
吸气剂
toString 方法
具有以下属性和方法的类医院（0.5m）
名称：字符串
地址：字符串
容量：整数
患者：患者类的数组列表（见下文）
医生：医生类的数组列表（见下文）
护士类 Nurse 的数组列表（见下文）
addDoctor 它将所有必需的属性作为输入来创建一个新的 Doctor 实例。该方法必须将新实例添加到医生数组列表中。
addPatient 将所有必需的属性作为输入来创建 Patient 的新实例。如果当前患者数量小于容量，则该方法必须将新实例添加到患者数组列表中。
addNurse 将所有必需的属性作为输入来创建 Nurse 的新实例。该方法必须将新实例添加到护士数组列表中。
具有以下属性的类 Person (0.2m)
名称：字符串
年龄：整数
使用以下属性和方法扩展类 Person 的类 Staff (0.4m)
部门：字符串
一个名为“earnings”的抽象方法返回一个双精度值表示员工的收入
使用以下内容扩展类 Person 的类 Patient (0.3m)
案例描述：字符串
扩展类 Staff 的类 Doctor 具有以下属性和方法：(0.3m)
特长：字符串
基本工资：双倍
实现将基本工资作为医生收入返回的方法收入
使用以下属性和方法扩展 Staff 类的 Nurse 类：(0.3m)
每周小时数：双倍
小时率：双倍
方法收入的实现返回 hoursPerWeek*hourRate 作为护士的收入

二传手，吸气剂哈哈哈哈哈哈
