S.O.L.I.D. Principles of Object Oriented Design

By Robert C. Martin in 1995, named by Michael Feathers

• S - Single-responsibilty principle ** A class should be responsible for one thing. ** That does not mean single task. ** Small class with specific names and responsibilty. ** Find one reason to change and take everything else out of the class.
• O - Open-close principle
• L - Liskov substitution principle
• I - Interface segregation principle
• D - Dependy Inversion Principle

Don't Repeat Yourself

The Boyscout Principle

• Don't try to rebuild a whole project when editing it. Instead, leave it cleaner than you found it.

Separation of concern

• Code should do what it is supposed to and nothing else.

Interfaces

• If you only have one type then an interace is not needed. IT helps to extend without need to modify.

YAGNI

• You ain't going to need it.

When if returns don't use else

Write programs that do one thing and do it well.
Write programs to work together.
Write programs to handle text streams, because that is a universal interface.
