Lab Description:
This lab demonstrates the temperature generator program. This program based on the user decision, generates a select number of random temperatures depending on the season. If the season winter is chosen, a temperature is generated between 20-40 degrees, if spring is chosen, a temperature is generated between 40-70 degrees, if summer is chosen, a temperature is generated between 70-90 degrees, if fall is chosen, a temperature is generated between between 40-60 degrees. The program calculates the maximum, minimum, first, last, the sum, and average of the temperatures generated. The way the program operates is through its entry in the do-while loop. Within the do-while loop, the using System.out.println statements to speak to user and using Scanner to receive the user’s input. Whatever season they respond with, the program enters the switch statement and according to there response it enters one the following seasons in the switch. Within in the season section, the program ask the user how many simulations they would want to do, then after the program will create 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. After the simulation is done, the program will ask the user if they would like to continue. The program will then enter an if-else statement, which will set a boolean variable to true or false that will continue the program. The do-while continues if value equals true.
