From a code-centric view, a class is a collection of functions and variables working together to support a common goal. When you get to the heart of it, though, classes handle custom data. The variables in a class store the data and functions manipulate the data. Classes provide a powerful and self-contained way of organizing and processing every type of custom data you can possibly think of. 2 Objects. Classes cannot do any real work themselves—for that they need to be instantiated as objects.
All cars have fuel tanks, so this behavior is easy to repeat for any car.
