Java 8 in action ebook
Important reading for all Java developers Java 8 introduces significant changes in the language and in the libraries. Every Java developer should be aware of the evolution of the language. The book is not a primer to Java programming; it assumes you are already a Java 6/7 developer. All new Java 8 topics are explained with a comparison of what it is commonly used in Java 6/7 applications, in terms of popular code structures and design patterns. For example, chapter 2 focus is on how to use new lamb Important reading for all Java developers Java 8 introduces significant changes in the language and in the libraries. Every Java developer should be aware of the evolution of the language. The book is not a primer to Java programming; it assumes you are already a Java 6/7 developer. All new Java 8 topics are explained with a comparison of what it is commonly used in Java 6/7 applications, in terms of popular code structures and design patterns. For example, chapter 2 focus is on how to use new lambda expression in the behavior parametrization used in some design patterns. All part 3 (chapters 8 to 12) is devoted to improve how we code, using the new Java 8 features (streams, Optional, Completable Future, new Date/ Time API). The last part of the book is on how we can improve the quality of our code by introducing a functional like approach and what will possibly be after Java 8. The book is well written, with several exercises.more.
