| | * 1. Single Responsibility Principle |
| | * one class - one responsibility |
| | * 2. Open/Closed Principle |
| | * open for extension, but closed for modification |
| | * 3. Liskov Substitution Principle |
| | * objects if superclass should be replaceable by objects of a subclass |
| | * 4. Interface Segregation Principle |
| | * clients should not be forced to depend on methods they don't use (=no bloated interfaces) |
| | * 5. Dependency Inversion Principle |
| | * high-level modules should not depend on low level modules. Both should depend on abstractions |
