Answer:
1: Don't repeat yourself (DRY).
2: Keep it simple (KISS)
3. Minimize Coupling
4. Maximize Cohesion
5. Hide Implementation Details
6. Law of Demeter
7: Open/Closed Principle
Explanation:
1. Avoiding repetition is probably the single most fundamental tenet in programming.
2. Simplicity should always be a key goal. Simple code takes less time to write, has fewer bugs, and is easier to modify.
3. Any section of code (code block, function, class, etc.) should minimize the dependencies on other areas of code. This is achieved by using shared variables as little as possible.
4. Code that has similar functionality should be found within the same component.
5. Hiding implementation details allows change to the implementation of a code component while minimally affecting any other modules that use the component.
6. Code components should only communicate with their direct relations (e.g. classes that they inherit from, objects that they contain, objects passed by argument, etc.)
7. Software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification. In other words, it is not recommended to write classes that people can modify, write classes that people can extend.
I hope this helps and I'm sorry if it doesn't.
Have a great day! :)
