Java 8, 9 and 10 Version Features

Discover the powerful features introduced in Java 8, Java 9, and Java 10 with this practical and easy-to-understand guide. Designed for students, beginners, developers, and professionals, this book explains how modern Java evolved and how these features can improve programming productivity, code readability, and application development.

Starting with Java 8, the book explores Lambda Expressions, Functional Interfaces, Stream API, Method References, Default and Static Methods in Interfaces, Optional, and the new Date and Time API. These features introduce functional programming concepts and provide cleaner, more efficient ways to write Java applications.

The book then covers Java 9 features, including the Java Platform Module System (JPMS), modules, JShell, private methods in interfaces, factory methods for collections, and improvements to the Stream API. It also introduces Java 10 features such as Local-Variable Type Inference using var, application class-data sharing, and other important platform enhancements.

With clear explanations, practical examples, and hands-on programming concepts, this book helps readers understand not only what changed in Java 8, 9, and 10, but also why these features matter in modern Java development.
