商品描述

Master the principles and techniques of multithreaded programming with the Java 8 Concurrency API

About This Book

  • Implement concurrent applications using the Java 8 Concurrency API and its new components
  • Improve the performance of your applications or process more data at the same time, taking advantage of all of your resources.
  • Construct real-world examples related to machine learning, data mining, image processing, and client/server environments

Who This Book Is For

If you are a competent Java developer with a good understanding of concurrency but have no knowledge of how to effectively implement concurrent programs or use streams to make processes more efficient, then this book is for you.

What You Will Learn

  • Design concurrent applications by converting a sequential algorithm into a concurrent one
  • Discover how to avoid all the possible problems you can get in concurrent algorithms
  • Use the Executor framework to manage concurrent tasks without creating threads
  • Extend and modify Executors to adapt their behavior to your needs
  • Solve problems using the divide and conquer technique and the Fork/Join framework
  • Process massive data sets with parallel streams and Map/Reduce implementation
  • Control data-race conditions using concurrent data structures and synchronization mechanisms
  • Test and monitor concurrent applications

In Detail

Concurrency programming allows several large tasks to be divided into smaller sub-tasks, which are further processed as individual tasks that run in parallel. All the sub-tasks are combined together once the required results are achieved; they are then merged to get the final output. The whole process is very complex. This process goes from the design of concurrent algorithms to the testing phase where concurrent applications need extra attention. Java includes a comprehensive API with a lot of ready-to-use components to implement powerful concurrency applications in an easy way, but with a high flexibility to adapt these components to your needs.

The book starts with a full description of design principles of concurrent applications and how to parallelize a sequential algorithm. We'll show you how to use all the components of the Java Concurrency API from basics to the most advanced techniques to implement them in powerful concurrency applications in Java.

You will be using real-world examples of complex algorithms related to machine learning, data mining, natural language processing, image processing in client / server environments. Next, you will learn how to use the most important components of the Java 8 Concurrency API: the Executor framework to execute multiple tasks in your applications, the phaser class to implement concurrent tasks divided into phases, and the Fork/Join framework to implement concurrent tasks that can be split into smaller problems (using the divide and conquer technique). Toward the end, we will cover the new inclusions in Java 8 API, the Map and Reduce model, and the Map and Collect model. The book will also teach you about the data structures and synchronization utilities to avoid data-race conditions and other critical problems. Finally, the book ends with a detailed description of the tools and techniques that you can use to test a Java concurrent application.

Style and approach

A complete guide implementing real-world examples with algorithms related to machine learning, data mining, and natural language processing in client/server environments. All the examples are explained in a step-by-step approach.

- 提升應用程式的效能或同時處理更多數據,充分利用所有資源
- 構建與機器學習、數據挖掘、圖像處理和客戶端/服務器環境相關的實際範例

本書適合對並發有良好理解但不知如何有效實現並發程式或使用串流提高效能的熟練Java開發人員。

你將學到什麼
- 通過將順序算法轉換為並發算法來設計並發應用程式
- 發現並發算法可能出現的所有問題
- 使用Executor框架管理並發任務而無需創建執行緒
- 擴展和修改Executors以適應你的需求
- 使用分治技術和Fork/Join框架解決問題
- 使用並行串流和Map/Reduce實現處理大型數據集
- 使用並發數據結構和同步機制控制數據競爭條件

詳細內容
並發程式設計將大型任務分解為較小的子任務,這些子任務作為獨立任務並行運行。一旦獲得所需結果,所有子任務將合併以獲得最終輸出。整個過程非常複雜。從設計並發算法到測試階段,並發應用程式需要額外的注意。Java提供了一個全面的API,其中包含許多可立即使用的組件,以便以簡單的方式實現功能強大的並發應用程式,同時具有高度靈活性,可根據需求調整這些組件。

本書首先詳細介紹並發應用程式的設計原則以及如何將順序算法並行化。我們將向您展示如何從基礎知識到最高級技巧使用Java Concurrency API的所有組件,在Java中實現功能強大的並發應用程式。

您將使用與機器學習、數據挖掘、自然語言處理和客戶端/服務器環境相關的複雜算法的實際範例。接下來,您將學習如何使用Java 8 Concurrency API的最重要組件:Executor框架在應用程式中執行多個任務、phaser類實現分階段的並發任務以及Fork/Join框架實現可分割為較小問題的並發任務(使用分治技術)。最後,我們將介紹Java 8 API中的新功能,包括Map和Reduce模型以及Map和Collect模型。本書還將教您使用數據結構和同步工具來避免數據競爭條件和其他關鍵問題。最後,本書詳細介紹了測試Java並發應用程式的工具和技術。

風格和方法
本書以實際範例實施機器學習、數據挖掘和自然語言處理相關的算法,並在客戶端/服務器環境中進行解釋。所有範例都以逐步的方式解釋。
