Description:
First a Sensor class is created. This is going to be the super class from which we will inherit methods and variables.
The Sensor class will contain at least an int field reading and the following methods: setReading, getReading. Method setReading() will generate a reading value between 0 and 100. Overloaded method setReading( int u) will generate a reading value between 0 and u with 0 <= u <= 100. Overloaded method setReading( int l, int u) will generate a reading value between l and u with 0 <= l <= u <= 100. Method getReading() will return the last reading generated.
Next a TemperatureSensor class will be created. TemperatureSensor that will inherit class Sensor and will implement the following 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 HumiditySensor that will inherit class Sensor and will implement the following methods: getHumidity, getLowHumidity, getHighHumidity. Method getHumidity should return a number between 0-100, getLowHumidity between 0-50, getHighHumidity between 50-100. These methods must be implemented by calling the super class methods appropriately.
Another class SensorsStatsApp that will implement the application. In the application you will display a menu that will first 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. After that, another menu will 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.
