: Always specify types (e.g., List , not List ) to catch errors at compile time. : Always override them together
: Inheritance breaks encapsulation; use wrappers or delegates instead. : Always override them together
The book’s mantra is: If you follow these patterns, your code will be idiomatic and maintainable. To help you apply these concepts:
