Java写一个灯和空调风扇（能耗统计），基础数据：教室、灯、空调、风扇、电表

好的，以下是一个简单的Java实现，包括教室、灯、空调、风扇和电表类。

教室类 Classroom：

public class Classroom {
    private String name;
    private Light light;
    private AirConditioner airConditioner;
    private Fan fan;
    private ElectricityMeter electricityMeter;

    public Classroom(String name) {
        this.name = name;
        light = new Light();
        airConditioner = new AirConditioner();
        fan = new Fan();
        electricityMeter = new ElectricityMeter();
    }

    public void turnOnLight() {
        light.turnOn();
        electricityMeter.addElectricity(light.getPower());
    }

    public void turnOffLight() {
        light.turnOff();
    }

    public void turnOnAirConditioner() {
        airConditioner.turnOn();
        electricityMeter.addElectricity(airConditioner.getPower());
    }

    public void turnOffAirConditioner() {
        airConditioner.turnOff();
    }

    public void turnOnFan() {
        fan.turnOn();
        electricityMeter.addElectricity(fan.getPower());
    }

    public void turnOffFan() {
        fan.turnOff();
    }

    public double getElectricityConsumption() {
        return electricityMeter.getElectricityConsumption();
    }
}

灯类 Light：

public class Light {
    private boolean powerOn;
    private double power;

    public Light() {
        powerOn = false;
        power = 10; // 单位：瓦
    }

    public void turnOn() {
        powerOn = true;
        System.out.println("灯已开");
    }

    public void turnOff() {
        powerOn = false;
        System.out.println("灯已关");
    }

    public boolean isPowerOn() {
        return powerOn;
    }

    public double getPower() {
        return power;
    }
}

空调类 AirConditioner：

public class AirConditioner {
    private int temperature;
    private int mode; // 0: 制冷模式，1: 制热模式
    private boolean powerOn;
    private double power;

    public AirConditioner() {
        temperature = 25;
        mode = 0;
        powerOn = false;
        power = 1000; // 单位：瓦
    }

    public void turnOn() {
        powerOn = true;
        System.out.println("空调已开机");
    }

    public void turnOff() {
        powerOn = false;
        System.out.println("空调已关机");
    }

    public void setTemperature(int temperature) {
        if (powerOn) {
            if (mode == 0) { // 制冷模式
                if (temperature >= 16 && temperature <= 30) {
                    this.temperature = temperature;
                    System.out.println("温度已调至" + temperature + "度");
                } else {
                    System.out.println("制冷模式温度范围为16~30度");
                }
            } else { // 制热模式
                if (temperature >= 16 && temperature <= 30) {
                    this.temperature = temperature;
                    System.out.println("温度已调至" + temperature + "度");
                } else {
                    System.out.println("制热模式温度范围为16~30度");
                }
            }
        } else {
            System.out.println("请先开机");
        }
    }

    public void setMode(int mode) {
        if (powerOn) {
            if (mode == 0 || mode == 1) {
                this.mode = mode;
                System.out.println(mode == 0 ? "已切换至制冷模式" : "已切换至制热模式");
            } else {
                System.out.println("模式参数错误，0表示制冷模式，1表示制热模式");
            }
        } else {
            System.out.println("请先开机");
        }
    }

    public int getTemperature() {
        return temperature;
    }

    public int getMode() {
        return mode;
    }

    public boolean isPowerOn() {
        return powerOn;
    }

    public double getPower() {
        return power;
    }
}

风扇类 Fan：

public class Fan {
    private boolean powerOn;
    private double power;

    public Fan() {
        powerOn = false;
        power = 50; // 单位：瓦
    }

    public void turnOn() {
        powerOn = true;
        System.out.println("风扇已开");
    }

    public void turnOff() {
        powerOn = false;
        System.out.println("风扇已关");
    }

    public boolean isPowerOn() {
        return powerOn;
    }

    public double getPower() {
        return power;
    }
}

电表类 ElectricityMeter：

public class ElectricityMeter {
    private double electricityConsumption;

    public ElectricityMeter() {
        electricityConsumption = 0;
    }

    public void addElectricity(double electricity) {
        electricityConsumption += electricity;
    }

    public double getElectricityConsumption() {
        return electricityConsumption;
    }
}

以上是一个简单的实现，支持开关灯、空调和风扇，同时计算电表数据。可以根据具体需求进行扩展。
