Balanced Abstraction Principle
Sandro Mancuso, in his blog, defines the Balanced Abstraction Principle as follows:
The Balanced Abstraction Principle defines that all code constructs grouped by a higher-level construct should be at the same level of abstraction. That means:
- All instructions inside a method should be at the same level of abstraction.
- All public methods inside a class should be at the same level of abstraction.
- All classes should be inside a package/namespace.
- All sibling packages/namespace should be inside a parent package/namespace.

Let's see how it relates to a little previous example. In the following snippet, the Save method is not at the same level of abstraction:
public class Car{
public int CurrentMileage(){...}
public void TravelTo(Location location){...}
public void Save...
