## JAVA—出租车公司租车 ##

### 样例 ###

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzIwMTg1NzM3_size_16_color_FFFFFF_t_70_pic_center]

### 题目需求 ###

> 1.一个人去租车公司租车，车分为轿车、客车、电动车，轿车品牌有宝马（200）、奔驰（300）、奥拓（50）、客车品牌五菱（800）、长安（1500）；电动车有雅迪（20）、艾玛（50）、阳光（80）；根据租车类型、品牌、天数计算租车费用  
> 2.每类车都需要维护，轿车维护主要是加油；客车维护是清洁，电动车维护是补胎。出租公司每天都要对车辆进行维护。轿车还需要定期保养

### 分析 ###

> 1.有哪些类：轿车类、客车类、电动车类、宝马（车的品牌属性），车类、人类、公司类  
> 2.类之间的关系：车类是父类，轿车、客车、电车是子类  
> 3.每个类的属性：只要有继承关系，那么所有子类都有的属性放在父类，品牌、价格，子类还可以有自己的属性  
> 4.每个类的行为：只要有继承关系，那么所有子类都有的行为，如果实现一样，放在父类；如果某个行为子类都有，但是实现不一样，那么写成抽象方法放到父类，子类实现

### 代码块 ###
