Java 8 Lambdas Book Review

O'Reily's Java 8 Lambdas by Richard Warburn is a "must have" if you are starting with Java 8 or functional programming. The book covers the different features of Java 8, and how using lambdas make you a better programmer. Here are some topics that catched my attention:

  • Streams - separate the "what" from "how" 
  • Patterns to refactor using lambdas 
  • Higher order functions 
  • Lambda expressions can be used to make many existing design patterns simpler and more readable, especially the command pattern 
  • Lambda-Enabled Concurrency 
  • Lambda-Enabled SOLID principles
