Lab Description:

This Lab is carried on since from Lab 1 and Lab 2, extending it to be used with multiple classes and using inheritance to bring down some methods. Inheritance allows programmers the flexibility to share some traits between different classes and provides ability to do moderate modification or overwrite whole.

All the features that was added during Lab 1 and Lab 2 are preserved in this program. Some features that was preserved in the program are checking for wrong inputs and correctly leads the user through the menus using try/catch block. Added feature to the program includes random choice in the menu which the program randomly selects an option. Another feature is added humidity sensor simulation in addition to preexsisting temperature sensor.
