Data abstraction is the process of hiding certain details and showing only essential information to the user. Abstraction can be achieved with either abstract classes or interfaces (which you will learn more about in the next chapter). The abstract keyword is a non-access modifier, used for classes and methods:

Abstraction is a feature of OOPs. The feature allows us to hide the implementation detail from the user and shows only the functionality of the programming to the user. Because the user is not interested to know the implementation. It is also safe from the security point of view. Let's understand the abstraction with the help of a real-world example. The best example of abstraction is a car.

Let us look at it in the context of Java through this figure. 2015-01-27 · The principle also applies to tests—all tests for a single unit (method, class, module, system) should be at the same level of abstraction. BAP and SRP Code that complies with the Single Responsibility Principle has a higher chance to also be compliant to the Balanced Abstraction Principle. 2020-05-19 · Open/Closed Principle As the name suggests, this principle states that software entities should be open for extension, but closed for modification. As a result, when the business requirements change then the entity can be extended, but not modified. 2009-06-12 · One of the other useful principles for writing readable code that I’ve come across in the last year or so is the Single Level of Abstraction Principle.
