1. Book Description
   
2. Java 8 in Action is a clearly written guide to the new features of Java 8. The book covers lambdas, streams, and functional-style programming. With Java 8's functional features you can now write more concise code in less time, and also automatically benefit from multicore architectures. It's time to dig in!

4. 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.

3. Comparator<Apple> byWeight = new Comparator<Apple>() {
   
4.     public int compare(Apple a1, Apple a2){
   
5.         return a1.getWeight().compareTo(a2.getWeight());
   
6.     }
   
7. };
   
8. After (with lambda expressions):
