Lab Description:
Lab 2 is very similar to Lab 1 in the fact that it is using Temperature Generator program. But Lab 2 uses two separate classes, one called TemperatureSensorStats which contains the menu to call the temperature generator functions and the other class is called the Temperature Sensor which contains all the temperature generator functions for each season. Using a separate class (TemperatureSensorStats) to call the temperature generator functions, a new object must be made with a constructor using the TemperatureSensor class. In the main public class “TemperatureSensorStats”, the program asks the user what season would they like to simulate. When the user enters a menu number, the program goes into the switch and goes to the specific menu option, and within that menu option it callls the “tempgen()”, and “winter()” (winter is being used as an example, replace with function with the season chosen) from the TemperatureSensor class. After the functions are called then the program emulates the temperatures for the season they chosen based on the amount of simulations they requested. Upon exiting the program the user is asked if they would like to continue, and then based on that decision it changes boolean variable “value” to true or false which then either stops or continues the execution of the do while which the whole program is contained in. The TemperatureSensor class contains the following functions, tempgen(), winter(), spring(), summer(), fall(). The tempgen() function uses a system.out.println and asks the user how many simulations would they like to do, and accepts the users input. The winter(), spring(), summer(), fall() functions generate the temperatures by a for loop which contains a new object from the Random class that will generate the random temperatures. The for loop containing the random object will stop until it reaches the desired amount of simulations and output desired amount of random numbers, the sum, the average, highest temperature, lowest temperature, first temperature outputted, and the last temperature outputted.
