## Java-数组完成租车系统案例 ##

> 要求：实现租车的种类选择，租车的天数，折扣租赁的费用计算，分配汽车的牌号。

**创建汽车类：**

public class Automobile { 
        private String plate;//车牌
        private String brand;//品牌
        private int rent;//租金
    
        public Automobile(String plate, String brand, int rent) { 
            this.plate = plate;
            this.brand = brand;
            this.rent = rent;
        }
    
        public String getPlate() { 
            return plate;
        }
    
        public void setPlate(String plate) { 
            this.plate = plate;
        }
    
        public String getBrand() { 
            return brand;
        }
    
        public void setBrand(String brand) { 
            this.brand = brand;
        }
    
        public int getRent() { 
            return rent;
        }
    
        public void setRent(int rent) { 
            this.rent = rent;
        }
    }

**创建轿车类：**

public class Car extends Automobile { 
        private String model;//型号
    
        public Car(String plate, String brand, int rent, String model) { 
            super(plate, brand, rent);
            this.model = model;
        }
    
    
        public String getModel() { 
            return model;
        }
    
        public void setModel(String model) { 
            this.model = model;
        }
    }

**创建客车类：**

public class Bus extends Automobile { 
        private String seatNumber;//座位数
    
        public Bus(String plate, String brand, int rent, String seatNumber) { 
            super(plate, brand, rent);
            this.seatNumber = seatNumber;
        }
    
        public String getSeatNumber() { 
            return seatNumber;
        }
    
        public void setSeatNumber(String seatNumber) { 
            this.seatNumber = seatNumber;
        }
    }

**汽车租赁管理类：**

public class AutomobileManage { 
        /*初始化轿车*/
        public Car[] initCar(){ 
            Car car1 = new Car("京NY28588","宝马",800,"X6");
            Car car2 = new Car("京CNY3282","宝马",600,"550i");
            Car car3 = new Car("京NT37465","别克",300,"绿荫大道");
            Car car4 = new Car("京NT96968","别克",600,"GL8");
    
            Car[] cars={ car1,car2,car3,car4};
    
            return cars;
        }
        /*初始化客车*/
        public Bus[] initBus(){ 
            Bus bus1 = new Bus("京5673432","金杯",800,"16");
            Bus bus2 = new Bus("京NY28555","金龙",800,"16");
            Bus bus3 = new Bus("京NY23274","金杯",1500,"34");
            Bus bus4 = new Bus("京NY28573","金龙",1500,"34");
    
            Bus[] buses={ bus1,bus2,bus3,bus4};
    
            return buses;
        }
    }

**汽车业务类：**

public class AutomobileService { 
        /*租车服务入口*/
        public void rentService(){ 
            System.out.println("**********欢迎来到秋名山租车系统************");

**测试类：**

public class Test { 
        public static void main(String[] args) { 
            AutomobileService automobileService = new AutomobileService();
            automobileService.rentService();
        }
    }
