TDA552 - Objektorienterad programmering och design

These are: Abstraction. Abstraction means using simple things to represent complexity. We all know how to turn the TV on, but we don’t need to know how it works in order to enjoy it. In Java, abstraction means simple things like objects, classes, and variables represent more complex underlying code and data. This is important because it lets avoid repeating the same work multiple times.

It is a process of hiding complex internal implementation details from the user and The next core principle of object-oriented programming we are about to examine is "abstraction".

Java provides a non-access modifier “abstract” for implementing abstraction. On the one hand, abstraction is more in line with people’s thinking habits; on the other hand, according to the Richter’s replacement principle, it is easy to replace the original abstraction with the expanded concrete, which can well support the open close principle. By introducing an abstraction C (maybe Java interface in Java program) between A and B, now the direction of dependency is now from B to C, which inverses the dependency Benefit De-coupling of code between modules; Dependency Inversion Principle Tips.
