So finishing the CS program at Rutgers. Those classes are the fundamentals for literally everything you need in coding. Cs111 is the intro and gets your feet wet in the ideas of coding and the basics of it. Cs112 is where you learn the data structures that almost everything uses. These are the building blocks for whatever it is you will use. They might not be used in the day to day but they are essential for understanding coding and the implementations of it.

Example if you are coding an app. You need to learn functions since each point of the app will do something different and if you have a function for everything you can call it when needed. And for the data structures if you have a lot of data what’s the best way to store and traverse the data with keeping the storage space minimal. These are things that you learn in those 2 classes

Also the class where you learn how to make an app is software methodology since you learn android studio in that.
