About the Book
Every new version of Java is important,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,using real-world Java code. Next,it covers the new Streams API and shows how you can use it to make collection-based code radically easier to understand and maintain. 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.
