Data abstraction refers to providing only essential information to the outside world and hiding their background details, i.e., to represent the needed information in program without presenting the details. Its main goal is to handle complexity by hiding unnecessary details from the user. This is because of the abstraction we used, even if the code changed entirely. From the outside, a car is a single object. Depending on your choice of coffee, they decide which of the available coffee beans to use and how to grind them. Lets start by defining our class (I wont be defining type validation to keep the code cleaner, but you should do it): So we defined multiple methods and we have a lot of stuff now that we can do: For a 2D Vector this may seem simple. A class that consists of one or more abstract method is called the abstract class. These are two ways of implementing the abstraction 'greet other person' A human programmer can write their software in these easier-to-use languages, and then the computer converts the script into something it understands - the machine code - via an interpreter or compiler. All the implementations are done inside the sub-classes. In plain English, abstraction is a simplified view of the world, focused on looking at an overview of an object rather than individual details. The brewFilterCoffee and brewEspresso methods abstract the specific operations required to brew the coffee. java was designed to abstract away some of the lower-level aspects of c++ such as memory management.
