用Java语言建立一个家用电器类，作为实验3中建立的电视类的父类。（注意构造函数） 修改电视类的设计，使其继承于家用电器类。 增加一个空调类，使其同样继承于家用电器类。 设计空调类的成员属性和成员方法。（注意分析空调功能的多样性：制冷；制热；除湿；换新风等。） 同实验3相同，要考虑其构造函数的设计。 为本次实验设计一个测试类，用以实现以上类的功能设计。

家用电器类:

public class Appliances {
    private String brand;
    private String model;
    private double price;

    public Appliances(String brand, String model, double price) {
        this.brand = brand;
        this.model = model;
        this.price = price;
    }

    public String getBrand() {
        return brand;
    }

    public String getModel() {
        return model;
    }

    public double getPrice() {
        return price;
    }

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

电视类:

public class Television extends Appliances {
    private int size;
    private String resolution;
    private boolean smartTV;

    public Television(String brand, String model, double price, int size, String resolution, boolean smartTV) {
        super(brand, model, price);
        this.size = size;
        this.resolution = resolution;
        this.smartTV = smartTV;
    }

    public int getSize() {
        return size;
    }

    public void setSize(int size) {
        this.size = size;
    }

    public String getResolution() {
        return resolution;
    }

    public void setResolution(String resolution) {
        this.resolution = resolution;
    }

    public boolean isSmartTV() {
        return smartTV;
    }

    public void setSmartTV(boolean smartTV) {
        this.smartTV = smartTV;
    }
}

空调类:

public class AirConditioner extends Appliances {
    private boolean heating;
    private boolean cooling;
    private boolean dehumidifying;

    public AirConditioner(String brand, String model, double price, boolean heating, boolean cooling, boolean dehumidifying) {
        super(brand, model, price);
        this.heating = heating;
        this.cooling = cooling;
        this.dehumidifying = dehumidifying;
    }

    public boolean isHeating() {
        return heating;
    }

    public void setHeating(boolean heating) {
        this.heating = heating;
    }

    public boolean isCooling() {
        return cooling;
    }

    public void setCooling(boolean cooling) {
        this.cooling = cooling;
    }

    public boolean isDehumidifying() {
        return dehumidifying;
    }

    public void setDehumidifying(boolean dehumidifying) {
        this.dehumidifying = dehumidifying;
    }
}

测试类:

public class Test {
    public static void main(String[] args) {
        Television tv = new Television("Sony", "Bravia", 999.99, 50, "4K", true);
        System.out.println(tv.getBrand());
        System.out.println(tv.getModel());
        System.out.println(tv.getPrice());
        System.out.println(tv.getSize());
        System.out.println(tv.getResolution());
        System.out.println(tv.isSmartTV());

        AirConditioner ac = new AirConditioner("Daikin", "Smart Inverter", 799.99, true, true, true);
        System.out.println(ac.getBrand());
        System.out.println(ac.getModel());
        System.out.println(ac.getPrice());
        System.out.println(ac.isHeating());
        System.out.println(ac.isCooling());
        System.out.println(ac.isDehumidifying());
    }
}
