Java by Comparison
Become a Java Craftsman in 70 Examples
by Simon Harrer, Jörg Lenhard, Linus Dietz
Improve your coding skills by comparing your code to that of expert
programmers so you can write code that’s clean, concise, and to the
point: code that others will read with pleasure and reuse. Get hands-on
advice to level up your coding style through small and understandable
examples that compare flawed code to an improved solution. Discover
handy tips and tricks, as well as common bugs an experienced Java
programmer needs to know. Make your way from a Java novice to a master
This book is a useful companion for anyone learning to write clean Java
code. The authors introduce you to the fundamentals of becoming a
software craftsman by comparing pieces of problematic code with an
improved version to help you to develop a sense for clean code. This
unique before-and-after approach teaches you to create clean Java code.
Learn to keep your booleans in check, dodge formatting bugs, get rid of
magic numbers, and use the right style of iteration. Write informative
comments when needed, but avoid them when they are not. Improve the
understandability of your code for others by following conventions and
naming your objects accurately. Make your programs more robust with
intelligent exception handling and learn to assert that everything works
as expected using JUnit5 as your testing framework. Impress your peers
with an elegant functional programming style and clear-cut
object-oriented class design.
Writing excellent code isn’t just about implementing the functionality.
It’s about the small important details that make your code more
readable, maintainable, flexible, robust, and faster. Java by
Comparison teaches you to spot these details and trains you to become a
