sailboat编程

sailboat编程是一种模拟帆船行驶的程序设计。在这个编程中，开发者会用不同的算法和模拟技术来模拟帆船在不同风力和海况下的航行情况。

这种编程可以用于虚拟船舶训练、航海实验等领域。在这些场景下，sailboat编程不仅可以模拟船只的航行轨迹，还可以模拟船只的操作、航行决策，从而帮助人们更好地理解帆船航行的原理和技巧。

另外，sailboat编程也可以应用在游戏开发中。通过这种编程，游戏开发者可以设计出更加真实和有挑战性的帆船游戏，提高游戏的体验和可玩性。

尽管sailboat编程在实际应用中有一定的局限性，但它对于帆船航行的模拟和理解有着重要的意义。通过这种编程，人们可以更好地了解帆船航行背后的科学原理，提高帆船驾驶的技能和技术水平。同时，这种编程也为航海训练和帆船游戏的发展提供了新的可能性和思路。

总的来说，sailboat编程是一种有着广泛应用前景和重要意义的程序设计，它有助于推动帆船航行技术的发展，提高人们对于帆船航行的理解和认识。

创建一个Boat（船）类，它有四个属性：registrationNo（注册 号）、length（长）、manufacturer（制造商）、year（年）， 方法toString返回所有属性的值。 SailBoat（帆船）类和PowerBoat（汽艇）类继承Boat类， SailBoat类还有keelDepth（龙骨深度）和id（帆船编号）属性， PowerBoat还有numberEgines（引擎数）和fuelType（燃料类 型）属性。在SailBoat类和PowerBoat类重写toString方法（要 求调用父类方法）。 分别创建三个类的对象，使用setter或构造方法赋值，输出其所 有属性值。java

以下是 Boat 类的实现：

public class Boat {
    private String registrationNo;
    private double length;
    private String manufacturer;
    private int year;

    public Boat(String registrationNo, double length, String manufacturer, int year) {
        this.registrationNo = registrationNo;
        this.length = length;
        this.manufacturer = manufacturer;
        this.year = year;
    }

    public String toString() {
        return "Registration No: " + registrationNo + "\nLength: " + length + "\nManufacturer: " + manufacturer + "\nYear: " + year;
    }
}

以下是 SailBoat 类的实现：

public class SailBoat extends Boat {
    private double keelDepth;
    private int id;

    public SailBoat(String registrationNo, double length, String manufacturer, int year, double keelDepth, int id) {
        super(registrationNo, length, manufacturer, year);
        this.keelDepth = keelDepth;
        this.id = id;
    }

    public String toString() {
        return super.toString() + "\nKeel Depth: " + keelDepth + "\nID: " + id;
    }
}

以下是 PowerBoat 类的实现：

public class PowerBoat extends Boat {
    private int numberEngines;
    private String fuelType;

    public PowerBoat(String registrationNo, double length, String manufacturer, int year, int numberEngines, String fuelType) {
        super(registrationNo, length, manufacturer, year);
        this.numberEngines = numberEngines;
        this.fuelType = fuelType;
    }

    public String toString() {
        return super.toString() + "\nNumber of Engines: " + numberEngines + "\nFuel Type: " + fuelType;
    }
}

以下是测试代码：

public class BoatTest {
    public static void main(String[] args) {
        Boat boat = new Boat("A1234", 10.5, "Boat Company", 2022);
        System.out.println(boat);

        SailBoat sailBoat = new SailBoat("B5678", 15.0, "Sailboat Company", 2022, 3.0, 1);
        System.out.println(sailBoat);

        PowerBoat powerBoat = new PowerBoat("C9101", 20.0, "Powerboat Company", 2022, 2, "Gasoline");
        System.out.println(powerBoat);
    }
}

输出结果如下：

Registration No: A1234
Length: 10.5
Manufacturer: Boat Company
Year: 2022

Registration No: B5678
Length: 15.0
Manufacturer: Sailboat Company
Year: 2022
Keel Depth: 3.0
ID: 1

Registration No: C9101
Length: 20.0
Manufacturer: Powerboat Company
Year: 2022
Number of Engines: 2
Fuel Type: Gasoline
