用Java代码设计一个汽车租赁系统

好的，下面是一个简单的汽车租赁系统的Java代码示例，包含了客户管理、车辆管理、订单管理、租赁管理等功能。由于篇幅限制，这里只提供代码框架，具体实现可以根据自己的需求进行相应的修改和完善。

// 客户类
public class Customer {
    private String name;
    private String id;
    private String phone;

    // 构造函数
    public Customer(String name, String id, String phone) {
        this.name = name;
        this.id = id;
        this.phone = phone;
    }

    // getter和setter方法
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }
}

// 车辆类
public class Vehicle {
    private String plateNumber;
    private String type;
    private String color;
    private double price;
    private double rent;

    // 构造函数
    public Vehicle(String plateNumber, String type, String color, double price, double rent) {
        this.plateNumber = plateNumber;
        this.type = type;
        this.color = color;
        this.price = price;
        this.rent = rent;
    }

    // getter和setter方法
    public String getPlateNumber() {
        return plateNumber;
    }

    public void setPlateNumber(String plateNumber) {
        this.plateNumber = plateNumber;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public String getColor() {
        return color;
    }

    public void setColor(String color) {
        this.color = color;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public double getRent() {
        return rent;
    }

    public void setRent(double rent) {
        this.rent = rent;
    }
}

// 订单类
public class Order {
    private Customer customer;
    private Vehicle vehicle;
    private Date rentDate;
    private Date returnDate;
    private double rent;

    // 构造函数
    public Order(Customer customer, Vehicle vehicle, Date rentDate, Date returnDate, double rent) {
        this.customer = customer;
        this.vehicle = vehicle;
        this.rentDate = rentDate;
        this.returnDate = returnDate;
        this.rent = rent;
    }

    // getter和setter方法
    public Customer getCustomer() {
        return customer;
    }

    public void setCustomer(Customer customer) {
        this.customer = customer;
    }

    public Vehicle getVehicle() {
        return vehicle;
    }

    public void setVehicle(Vehicle vehicle) {
        this.vehicle = vehicle;
    }

    public Date getRentDate() {
        return rentDate;
    }

    public void setRentDate(Date rentDate) {
        this.rentDate = rentDate;
    }

    public Date getReturnDate() {
        return returnDate;
    }

    public void setReturnDate(Date returnDate) {
        this.returnDate = returnDate;
    }

    public double getRent() {
        return rent;
    }

    public void setRent(double rent) {
        this.rent = rent;
    }
}

// 租赁系统类
public class RentalSystem {
    private List<Customer> customers;
    private List<Vehicle> vehicles;
    private List<Order> orders;

    // 构造函数
    public RentalSystem() {
        customers = new ArrayList<Customer>();
        vehicles = new ArrayList<Vehicle>();
        orders = new ArrayList<Order>();
    }

    // 客户管理
    public void addCustomer(Customer customer) {
        customers.add(customer);
    }

    public void updateCustomer(Customer customer) {
        // 根据客户id更新客户信息
    }

    public void deleteCustomer(String id) {
        // 根据客户id删除客户信息
    }

    public Customer findCustomer(String id) {
        // 根据客户id查找客户信息
        return null;
    }

    // 车辆管理
    public void addVehicle(Vehicle vehicle) {
        vehicles.add(vehicle);
    }

    public void updateVehicle(Vehicle vehicle) {
        // 根据车牌号更新车辆信息
    }

    public void deleteVehicle(String plateNumber) {
        // 根据车牌号删除车辆信息
    }

    public Vehicle findVehicle(String plateNumber) {
        // 根据车牌号查找车辆信息
        return null;
    }

    // 订单管理
    public void addOrder(Order order) {
        orders.add(order);
    }

    public void updateOrder(Order order) {
        // 根据订单号更新订单信息
    }

    public void deleteOrder(String id) {
        // 根据订单号删除订单信息
    }

    public Order findOrder(String id) {
        // 根据订单号查找订单信息
        return null;
    }

    // 租赁管理
    public boolean rentVehicle(String id, String plateNumber, Date rentDate, Date returnDate) {
        // 根据客户id和车牌号出租车辆
        return false;
    }

    public boolean returnVehicle(String id, String plateNumber, Date returnDate) {
        // 根据客户id和车牌号归还车辆
        return false;
    }

    // 统计报表
    public List<Order> getOrderReport(Date startDate, Date endDate) {
        // 根据日期范围生成订单报表
        return null;
    }

    public double getIncomeReport(Date startDate, Date endDate) {
        // 根据日期范围生成收入报表
        return 0.0;
    }
}
