Java 9 0 To 13 0 New Features

A comprehensive guide to study the version updates from JDK9.0 to JDK13.0 DESCRIPTIONÊ Version release is one of the important phases of success of any programming language. Over the years, Java had made many improvements in its API to make to reliable and flexible to use. This book aims at providing you information related to all the updates from JDK9.0 to JDK13.0 in one place. Ê This book starts with a brief history of Java. It covers how Java has evolved as a complete programming language over the years by launching different versions.Ê You will learn the concept of module system and other important concepts introduced in JSE9 .0 and JSE10.0. Moving ahead, the book will take you through updates in JDK11.0. Concepts like Epsilon, ZGC, and Nest-Based access control have also been discussed. Though the version updates are good to learn, they create complexities in updating the existing code to make it compatible with the new version. This book talks in detail about how you can migrate your legacy code to match up with the new versions. It also covers how to use jshell, a tool used to test your code snippet without writing the complete application class, with numerous examples. Further, this book covers in detail the concept of reactive programming. Concepts like publisher, subscriber, subscription and back-pressure have been discussed with examples. At the end of the book, you will learn about the very recent updates which have been released by Java. The chapters talk about JDK12.0 and JDK13.0. They cover concepts like Shenondaoh, microbenchmark suit, modified switch expression from JDK12.0. Though Java13 is still a hot-plated dish, this book gives you a fair idea about what are the new updates which have been proposed in this version. Ê KEY FEATURES _Ê Ê Ê Learn the journey of Java from its initial days till date. _Ê Ê Ê Learn how to implement modular programming in java9. _Ê Ê Ê Study the updates in different versions of Java from version 9.0 to 13.0. _Ê Ê Ê Understand the need and working of reactive programming. _Ê Ê Ê Learn to migrate the pre-existing Java code to new versions. _Ê Ê Ê Learn how to use jshell to test a new API before using in a project. Ê WHAT WILL YOU LEARN By the end of this book, you will be able to implement the updates provided in different versions of Java. This book has covered the updates from version 9.0 to 13.0. You will be able to work with the Java Module System. You will be able to test the new API using jshell.Ê Along with this, you will be able to migrate your legacy code to match the recommendations of new versions of Java. Ê WHO THIS BOOK IS FOR This book covers the new version updates in Java. So, prior knowledge of Java is recommended before reading this book. Though we are covering the versions from JSE9.0 onwards, it is not necessary that the reader should be expert in the earlier versions. If you are keen to know the recent developments in Java API, this is the perfect book for you. Ê Table of Contents 1. Insights of Versioning 2. WhatÕs new in Java9 3.

Develop your coding skills by exploring Java concepts and techniques such as Strings, Objects and Types, Data Structures and Algorithms, Concurrency, and Functional programming Key FeaturesSolve Java programming challenges and get interview-ready by using the power of modern Java 11Test your Java skills using language features, algorithms, data structures, and design patternsExplore areas such as web development, mobile development, and GUI programmingBook Description The super-fast evolution of the JDK between versions 8 and 12 has increased the learning curve of modern Java, therefore has increased the time needed for placing developers in the Plateau of Productivity. Its new features and concepts can be adopted to solve a variety of modern-day problems. This book enables you to adopt an objective approach to common problems by explaining the correct practices and decisions with respect to complexity, performance, readability, and more. Java Coding Problems will help you complete your daily tasks and meet deadlines. You can count on the 300+ applications containing 1,000+ examples in this book to cover the common and fundamental areas of interest: strings, numbers, arrays, collections, data structures, date and time, immutability, type inference, Optional, Java I/O, Java Reflection, functional programming, concurrency and the HTTP Client API. Put your skills on steroids with problems that have been carefully crafted to highlight and cover the core knowledge that is accessed in daily work. In other words (no matter if your task is easy, medium or complex) having this knowledge under your tool belt is a must, not an option. By the end of this book, you will have gained a strong understanding of Java concepts and have the confidence to develop and choose the right solutions to your problems.

This book assumes very little or no knowledge of how computers work, and shows how to write understandable programs in Java. Even though most readers will not wish to become professional programmers, programming is fun and useful, and, in today's world it is important for professionals in any field to appreciate what computers can (and cannot) do well. To reach this level of understanding, Per Brinch Hansen goes beyond the routine skills of a computer user and explains the art of programming in some depth, allowing readers to write Java programs for use on the WWW or company's Intranet. Although a book about programming with Java, the same methods can be used for systematic programming in such languages as C, Fortran, and Pascal. The book makes a splendid text for a one semester course on beginning programming and is backed by teaching aids available at the author's Website.
