: Always provide a useful implementation to make debugging easier.

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

: Always override them together. If you break this, HashMap and HashSet will fail. : Always provide a useful implementation to make

: Interfaces allow for flexible, "mixin" type behavior. 4. Generics and Enums

"Java: Эффективное программирование" (Effective Java) by Joshua Bloch is the definitive guide for writing high-quality Java code. It focuses on rather than basic syntax. Core Pillars of the Guide 1. Object Creation and Destruction If you break this, HashMap and HashSet will fail

: They have names and aren't required to create a new object every time.

The book’s mantra is: If you follow these patterns, your code will be idiomatic and maintainable. To help you apply these concepts: 2. Methods Common to All Objects

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