空客（Airbus）、波音（Boeing）、麦道（McDonnell-Douglas）都是飞机制造商，他们都可以生产载客飞机（PassengerPlane）、载货飞机（CargoPlane），请写一段java代码使用桥接模式来描述飞机制造商和他们生产的飞机。

好的，以下是符合您要求的Java桥接模式代码示例：

interface PlaneManufacturer {
    void producePlane(PlaneType type);
}

class Airbus implements PlaneManufacturer {
    @Override
    public void producePlane(PlaneType type) {
        if (type == PlaneType.PASSENGER) {
            System.out.println("Airbus produces passenger plane.");
        } else if (type == PlaneType.CARGO) {
            System.out.println("Airbus produces cargo plane.");
        }
    }
}

class Boeing implements PlaneManufacturer {
    @Override
    public void producePlane(PlaneType type) {
        if (type == PlaneType.PASSENGER) {
            System.out.println("Boeing produces passenger plane.");
        } else if (type == PlaneType.CARGO) {
            System.out.println("Boeing produces cargo plane.");
        }
    }
}

class McDonnellDouglas implements PlaneManufacturer {
    @Override
    public void producePlane(PlaneType type) {
        if (type == PlaneType.PASSENGER) {
            System.out.println("McDonnell-Douglas produces passenger plane.");
        } else if (type == PlaneType.CARGO) {
            System.out.println("McDonnell-Douglas produces cargo plane.");
        }
    }
}

enum PlaneType {
    PASSENGER, CARGO
}

abstract class Plane {
    protected PlaneManufacturer manufacturer;
    
    public Plane(PlaneManufacturer manufacturer) {
        this.manufacturer = manufacturer;
    }
    
    abstract void produce();
}

class PassengerPlane extends Plane {
    public PassengerPlane(PlaneManufacturer manufacturer) {
        super(manufacturer);
    }

    @Override
    void produce() {
        System.out.print("Passenger plane is produced by ");
        manufacturer.producePlane(PlaneType.PASSENGER);
    }
}

class CargoPlane extends Plane {
    public CargoPlane(PlaneManufacturer manufacturer) {
        super(manufacturer);
    }

    @Override
    void produce() {
        System.out.print("Cargo plane is produced by ");
        manufacturer.producePlane(PlaneType.CARGO);
    }
}

public class Main {
    public static void main(String[] args) {
        PlaneManufacturer airbus = new Airbus();
        PlaneManufacturer boeing = new Boeing();
        PlaneManufacturer mcdonnellDouglas = new McDonnellDouglas();
        
        Plane passengerPlane = new PassengerPlane(airbus);
        Plane cargoPlane = new CargoPlane(boeing);
        
        passengerPlane.produce(); // Passenger plane is produced by Airbus.
        cargoPlane.produce(); // Cargo plane is produced by Boeing.
    }
}

请问您还有其他问题需要我回答吗？
