Key Features

  • A full account of Java 9's new features
  • This tutorial emphasises fluency using JShell exercises
  • Get a thorough introduction to contract programming code reuse via Java generics
  • Learn how to use the new module system
  • How to use proper functional programming style inside Java 9

Book Description

The release of Java 9 has brought many subtle and not-so-subtle changes to the way in which Java programmers approach their code. The most important ones are definitely the availability of a REPL, known as JShell, which will make experiments and prototyping much more straightforward than the old IDE-based project-led approach. Another, more subtle change can be seen in the module system, which will lead to more modularized, maintainable code. The techniques to take full advantage of object-oriented code, functional programming and the new modularity features in Java 9 form the main subjects of this book.

Each chapter will add to the full picture of Java 9 programming starting out with classes and instances and ending with generics and modularity in Java.

What you will learn

  • Engage with object-oriented programming in Java 9, starting with code snippets in JShell
  • Optimize your code, applying functional programming features
  • Discover the advantages of modularity
  • Become very proficient at using JShell itself
  • Learn the new approach to Java programming, which uses the REPL as a prototyping tool

主要特點


  • Java 9的新功能全面介紹

  • 本教程強調使用JShell練習來提高熟練度

  • 通過Java泛型深入介紹契約編程代碼重用

  • 學習如何使用新的模塊系統

  • 如何在Java 9中使用正確的函數式編程風格

書籍描述

Java 9的發布為Java程序員在編寫代碼時帶來了許多微妙而明顯的變化。其中最重要的變化無疑是REPL(即JShell)的可用性,它將使實驗和原型開發比舊的基於IDE的項目導向方法更加簡單直接。另一個更微妙的變化可以在模塊系統中看到,它將導致更模塊化、可維護的代碼。本書的主要主題是如何充分利用Java 9中的面向對象編程、函數式編程和新的模塊化功能。

每一章都將從類和實例開始,最終涵蓋Java中的泛型和模塊化,為Java 9編程提供全面的圖景。

你將學到什麼


  • 通過JShell中的代碼片段與Java 9的面向對象編程互動

  • 應用函數式編程特性優化代碼

  • 發現模塊化的優勢

  • 熟練使用JShell本身

  • 學習使用REPL作為原型開發工具的新的Java編程方法
