Lab Description:
This Lab was by far the most intricate as it incorporated the previous two labs and required the utilization of inheritance. The lab required making 3 classes, 2 of which inherited the 1st class. Afterwards a main method was supposed to implement the methods from the above mentioned classes and create a program which as the previous labs printed out statistical data regarding Temperature and a new Statistical data similar to the temperature statistical data structure called humidity. Additionally a feature for the user was added to allow random selection. This lab was very troublesome to accomplish to its length and confusing inheritance requirement.
