Description
Book Synopsis DESCRIPTION
Functional programming is a deep and potentially mind-bending
discipline. Fortunately, Java developers don't have to master every
aspect of FP to get a big boost in the performance, readability, and
maintainability of their applications. By learning a few core FP
principles, they can write code that's less prone to side effects and
unwanted dependencies and which is much better suited to the parallel
processing required by modern multi-core and distributed systems. Also,
because units of functional code are designed to be modular and
independent, FP reduces or eliminates many of the bugs development
teams routinely face when managing a large codebase.
Functional Programming in Java teaches Java developers how to
incorporate the most powerful benefits of functional programming into
new and existing Java code. Written to meet the needs of professional
Java developers who want to introduce functional programming
principles into new and legacy projects, this book uses examples,
exercises, and illustrations to teach core FP principles such as referential
transparency, immutability, persistence, and laziness. They’ll discover
which of the new functionally-inspired features of Java 8 will help in
applying FP principles to code—as well as which to avoid. In the end,
they’ll be able to think functionally about coding tasks in Java and use
FP to make their applications easier to understand, optimize, maintain,
and scale.
KEY FEATURES
• Increases productivity • Easy to grasp examples and illustrations • Written for professional Java developers AUDIENCE
Readers need to be comfortable with Java programming. No previous
experience with functional programming is required.
ABOUT THE TECHNOLOGY
Functional programming is gaining momentum, mainly through adoption of
new languages such as Scala, Clojure or Groovy, and through the new
popularity of older languages such as Haskell or Erlang. And functional
programming is coming to Java 8 with the addition of features such as
lambda expressions, and Streams.
