不同温度检测空调运转情况

        Car temperature1 = new Car(60);
        temperature1.getAir().flow();

    }

        public void flow() {

            if (temperature < 0) {
                System.out.println("开始吹暖风。。。");
            } else if (temperature > 40) {
                System.out.println("开始吹冷风。。。");
            } else {
                System.out.println("温度正常，关闭空调");
            }
        }
    }

    //写一个方法，返回创建Air
    public Air getAir() {
        return new Air();
