Introduction:
This lab is similar to lab 2 but we are using inheritance. First we must create a new class named Sensor. This sensor class will have a set and get method for reading. A setReading() method will generate random numbers between 0 and 100., while a setReading(int u) method will generate random numbers between 0 and u, and another overloaded method setReading( int l, int u) will generate a reading value between l and u. getReading() method will return the value of the interger reading. another class TemperatureSensor is created which will have methods getWinterTemp, getSpringTemp, getSummerTemp, getFallTemp. Method getWinterTemp should return a number between 20-40, getSpringTemp between 40-70, getSummerTemp between 70-90, and getFallTemp between 40-60. Another class would be created called HumiditySensor. It would have methods that are inherited from the Sensor class which would be called getHumidity, getLowHumidity, getHighHumidity. The method getHumidity should return a number between 0-100, getLowHumidity between 0-50, getHighHumidity between 50-100. Finally a new class is created which will contain the main methods to run the application. The class is call SensorApp. The application will ask the user what season to simulate, (1) winter (2) spring (3) summer (4) fall (5) random (6) exit. Random will choose the season for the user. Then ask the user what type of humidity to simulate (1) full range (2) low (3) high (4) random (5) exit. Random will choose the type of humidity for the user. After, the application would ask how many simulation the user want to generate for each decision made for season and humidity.
Season: _________ (if random, then display Random:Summer for example)
1- First temperature generated
2- Last temperature generated
3- Lowest temperature generated
4- Highest temperature generated
5- Total sum of all temperatures generated
6- Average for the season
Humidity Type: _________ (if random, then display Random:Full for example)
1- First humidity reading generated
2- Last humidity reading generated
3- Lowest humidity reading generated
4- Highest humidity reading generated
5- Total sum of all humidity readings generated
6- Average humidity reading
