By Michael Bevilacqua-Linn

Solve real-life programming issues of a fragment of the code that natural object-oriented programming calls for. Use Scala and Clojure to resolve in-depth issues of units of styles: object-oriented styles that develop into extra concise with practical programming, and natively sensible styles. Your code could be extra declarative, with fewer insects and reduce upkeep costs.

Functional languages have their very own styles that make it easier to remedy issues of much less code than object-oriented programming on my own. This ebook introduces you, the skilled Java programmer, to Scala and Clojure: sensible, production-quality languages that run at the JVM and interoperate with current Java. through the use of either the statically typed, type-inferred Scala and the dynamically typed, smooth Lisp Clojure, you are going to achieve a extensive figuring out of useful programming.

For every one trend, you will first see the conventional object-oriented resolution, after which dig into the sensible replacements in either Scala and Clojure. those styles are universal within the sensible international and need to turn into a part of your problem-solving toolkit. at the object-oriented part, you will see many universal styles, similar to Command, technique, and Null item. at the sensible part, you are going to study middle sensible styles corresponding to Memoization, Lazy series, and Tail Recursion.

Each trend is helping you resolve a typical programming challenge. operating via them grants a suite of styles you should use to resolve difficulties you return throughout whereas writing courses. ultimately, you are going to tips on how to paintings your latest Java code into new Scala or Clojure tasks. you can begin off small, including sensible code bit by bit, so that you can supplement your current wisdom with Scala and Clojure as those languages achieve reputation at the JVM.
