| JAVA 8 IN ACTION |
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.
