Answer 1

A class, in object-oriented programming, can best be thought of as a template for an object that can hold various variables and functions that “belong” to it.

You can have an Automobile class that has variables like its mileage, fuel capacity, whether it’s front- or rear-wheel drive, as well as functions like start(), shiftGears(), useRadio(), and others.

Then, you can create an Automobile object, and it automatically has its own variables and methods that you can independently interact with.
