Edited by Kevlin Henney and Trisha Gee, 97 Things Every Java Programmer Should Know reflects lifetimes of experience writing Java software and living with the process of software development. Great programmers share their collected wisdom to help you rethink Java practices, whether working with legacy code or incorporating changes since Java 8.
A few of the 97 things you should know:
"Behavior Is Easy, State Is Hard"—Edson Yanaga
“Learn Java Idioms and Cache in Your Brain”—Jeanne Boyarsky
“Java Programming from a JVM Performance Perspective”—Monica Beckwith
"Garbage Collection Is Your Friend"—Holly K Cummins
“Java's Unspeakable Types”—Ben Evans
"The Rebirth of Java"—Sander Mak
“Do You Know What Time It Is?”—Christin Gorman
“97 Things Every Java Programmer Should Know” covers quite a variety of “”things.” There are about 70 contributors with most writing 1 “thing.” Under ten people to contribute 3 “things” and I was one of them!
I like that the “things” cover a variety of technical and soft skills. They also don't just cover Java. They cover items you should know if your primary language is Java.
Many “things” I knew already or heard the authors speak about. However, there were some that I found new such as why Optional breaks monad conventions and why it is better. There were many common techniques and tools presented as well. Even Kotlin which Java developers should definitely at least read about.
I really liked the article about refactoring for speed-reading. Using common idioms and choosing names to help future readers is really important. One article suggests Googling for common interview questions if you face gotchas/be the compiler errors at interviews. I say buy a cert book to supplement this one
The “things” are presented in alphabetical order by title. At the end is the bio of all authors. That I expected. What pleasantly surprised me was that each bio ended with which articles the person contributed to the book. This is a really good reference.
This book reminded me of a conference. You get exposed to lots of information and decide what you want to explore more. Excellent collection!
I give this book 9 out of 10 horseshoes.
Disclosure: I received a copy of this book from the publisher in exchange contributing 3 “things”.
