Description

Lab 1 is to create a java program that simulates a temperature sensor. It allows user to pick a season and an exit trigger, then the program will generate numbers of random temperatures as many as user wants. Temperature will be generated to the proper degree within the season, such for winter a number between 20-40, for spring between 40-70, for summer between 70-90, and for fall between 40-60. After each simulation, the program will display the following items.

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
