JAVA Person类

1、   设计一个图书类Book，该Book类具有属性：书籍编号（bookId），书名(bookName)，作者(author)，出版单位(publisher)，单价(price)。

a)  要求属性私有，生成其共有的get/set 方法；

b)  具有方法：show（）：该方法内显示给书籍的详细信息

c)  在创建一个Book对象的同时给该对象各属性赋初值。（带参构造）

d)  编写测试类TestBook,实现创建一个Book对象book，打印出该书的详细信息。

 

2、   设计一个车辆类Vehicle，该Vehicle类具有属性：车辆型号（vehId），用途(vehUse)，性能(author)，油耗(oil)，颜色（color）,价钱(price)。

a)  要求属性私有，生成其共有的get/set 方法；

b)  具有方法：show（）：该方法内显示该车的的详细信息

c)  具有方法：start(),stop();

d)  在创建一个Vehicle对象的同时给该对象各属性赋初值。（带参构造）

e)  编写测试类TestVehicle,实现创建一个Vehicle对象Vehicle，打印出该车的详细信息。

 

3、   设计一个Person类，Person类具有属性：身份证号（idCard），姓名(name)，性别（sex），年龄（age）。

a)  要求属性私有，生成其共有的get/set 方法；

b)  具有方法：sleep()；eat（String food）；String listenAndSpeak（String word）

c)  具有方法：buy(Book book)，buy(Vehicle vehicle)

d)  在创建一个Person对象的同时给该对象各属性赋初值。（带参构造）

e)  编写测试类TestPerson,实现创建一个对象，并依次调用其上述各方法。
