The definitive guide to Java programming language best practices from Josh Bloch

Each chapter of Effective Java, Third Edition, consists of several “items,” each presented in the form of a short, stand-alone essay that provides specific advice, insight into Java platform subtleties, and code examples. The comprehensive descriptions and explanations for each item illuminate what to do, what not to do, and why. While coverage is through Java 9, this guidance covers core Java features every programmer works with, regardless of which version.

Concurrency: write clear, correct, well-documented concurrent programs
Objects: creating and destroying; common methods
Classes and interfaces: guidelines for making them usable, robust, and flexible
Generics: tell the compiler what types of objects are permitted in each collection for safer and clearer programs
Enums and annotations: two special-purpose families of reference types
Functions: break a big job into smaller pieces that might well be written by different people separated by both time and space.
Lambdas and streams: create function objects with more ease
Method designs: treat parameters and return values; design method signatures; document methods
Exceptions: improve a program’s readability, reliability, and maintainability
Object serialization: the dangers of serialization and how to minimize them
General programming:
- local variables
- control structures
- libraries
- data types
- reflection
- native methods
- optimization
- naming conventions

Programmers still consider this the best book on Java programming today.
