The objective of this lab is to create a temperature sensor simulator similar to lab 1. This time, we must separate the temperatures in different classes. First we must create a class called Temperature sensor which will include different methods for each season; getWinterTemp, getSpringTemp, getSummerTemp, and getFallTemp. Each simulation will produce a random numbers as follows: For winter a number between 20-40, for spring between 40-70, for summer between 70-90, and for fall between 40-60. We must then create another class called, TemperatureSensorStats that will run the program. In the program we must display a menu that would ask the user what season to simulate (1) winter (2) spring (3) summer (4) fall or (5) to exit. If the user input values that are not in the choice option, we must prompt the user that he or she as enter the wrong value using the try and catch command.
We must then display these results to the user. The Program must run until the user exits it.
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
