Java-陣列完成租車系統案例

要求：實現租車的種類選擇，租車的天數，折扣租賃的費用計算，分配汽車的牌號。

建立汽車類：

public class Automobile {
    private String plate;//車牌
    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;
    }
}

建立轎車類：

public class Car extends Automobile {
    private String model;//型號

    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;
    }
}

建立客車類：

public class Bus extends Automobile {
    private String seatNumber;//座位數

    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;
    }
}

汽車租賃管理類：

public class AutomobileManage {
    /*初始化轎車*/
    public Car[] initCar(){
        Car car1 = new Car("京NY28588","寶馬",800,"X6");
        Car car2 = new Car("京CNY3282","寶馬",600,"550i");
        Car car3 = new Car("京NT37465","別克",300,"綠蔭大道");
        Car car4 = new Car("京NT96968","別克",600,"GL8");

        Car[] cars={car1,car2,car3,car4};

        return cars;
    }
    /*初始化客車*/
    public Bus[] initBus(){
        Bus bus1 = new Bus("京5673432","金盃",800,"16");
        Bus bus2 = new Bus("京NY28555","金龍",800,"16");
        Bus bus3 = new Bus("京NY23274","金盃",1500,"34");
        Bus bus4 = new Bus("京NY28573","金龍",1500,"34");

        Bus[] buses={bus1,bus2,bus3,bus4};

        return buses;
    }
}

汽車業務類：

public class AutomobileService {
    /*租車服務入口*/

        System.out.println("**********歡迎來到秋名山租車系統************");

        Scanner scanner = new Scanner(System.in);

        int type = scanner.nextInt();
        AutomobileManage automobileManage = new AutomobileManage();
        String brand;/*車的牌號*/
        int day;/*租車的天數*/
        if(type==1){
            Car[] cars = automobileManage.initCar();

            System.out.print("請選擇你要租憑的汽車品牌：別克，寶馬:");
            brand = scanner.next();
            String model;//車的型號

            if(brand.equals("寶馬")){
                System.out.print("請選擇你要租賃的汽車型號：X6，550i:");

測試類：

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