Effective Java

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.
