: Throw exceptions early (at the start of the method).

: Use this when constructors have many parameters (especially optional ones). : Throw exceptions early (at the start of the method)

: Interfaces allow for flexible, "mixin" type behavior. 4. Generics and Enums HashMap and HashSet will fail.

The book’s mantra is: If you follow these patterns, your code will be idiomatic and maintainable. To help you apply these concepts: : Throw exceptions early (at the start of the method)

: Pass resources to the constructor instead of hardcoding them (Singleton/Static utilities). 2. Methods Common to All Objects

: Enums are full-fledged classes providing type safety and powerful features.

: Always override them together. If you break this, HashMap and HashSet will fail.
