About the Book
Every new version of Java is vital, but Java 8 is a game changer. Java 8 in Action is a clearly written guide to the new features of Java 8. It begins with a practical introduction to lambdas, The use of real-world Java code. Next, it covers the new Streams API and shows how you’ll be able to use it to make collection-based code radically easier to be aware and care for. It also explains other major Java 8 features including default methods, Optional, CompletableFuture, and the new Date and Time API.
This book is written for programmers familiar with Java and basic OO programming.
