商品描述

Build optimized applications in Kotlin by learning how to smartly implement standard libraries.

Key Features

  • Get the most out of the Kotlin library to develop high-quality portable applications
  • Explore the powerful support for data processing and I/O operations
  • Discover ways to enhance your Android application development

Book Description

Given the verbosity of Java, developers have turned to Kotlin for effective software development. The Kotlin standard library provides vital tools that make day-to-day Kotlin programming easier. This library features the core attributes of the language, such as algorithmic problems, design patterns, data processing, and working with files and data streams.

The recipes in this book offer coding solutions that can be readily executed. The book covers various topics related to data processing, I/O operations, and collections transformation. We'll walk through effective design patterns in Kotlin and you'll understand how coroutines add new features to JavaScript.

As you make your way through the chapters, you'll learn how to implement clean, reusable functions and scalable interfaces containing default implementations. In the concluding chapters, we'll provide recipes on functional programming concepts, such as lambdas, monads, functors, and Kotlin scoping functions.

By the end of the book, you'll be able to address a range of problems that Kotlin developers face by implementing easy-to-follow solutions.

What you will learn

  • Work with ranges, progressions, and sequences in use cases
  • Add new functionalities to current classes with Kotlin extensions
  • Understand elements such as lambdas, closures, and monads
  • Build a REST API consumer with Retrofit and a coroutine adapter
  • Discover useful tips and solutions for making your Android projects
  • Explore the benefits of standard library features

Who this book is for

This book is for software developers who are familiar with Kotlin's basics and want to discover more advanced features and concepts, especially those provided by the Kotlin standard library. It's also ideal for experienced software developers who are familiar with the functional programming paradigm and other programming languages who want to switch to Kotlin. It will also help Java developers switch to Kotlin and integrate it into existing Java Virtual Machine (JVM) projects.

Table of Contents

  1. Charm of ranges, progressions and sequences
  2. Designing expressive functions and adjustable interfaces
  3. Shaping code with Kotlin functional programming features
  4. Powerful data processing
  5. Tasteful design patterns based on Kotlin built-in concepts
  6. Friendly I/O operations
  7. Making Asynchronous programming great again
  8. Unit tests with JUnit and Kotlin Mockito
  9. Miscellaneous

商品描述(中文翻譯)

在 Kotlin 中建立優化應用程式,學習如何巧妙實現標準庫。

主要特點:

- 充分利用 Kotlin 库以開發高品質的可攜式應用程式
- 探索強大的數據處理和 I/O 操作支援
- 發現增強 Android 應用程式開發的方法

書籍描述:

考慮到 Java 的冗長性,開發人員已轉向 Kotlin 進行有效的軟體開發。Kotlin 標準庫提供了使日常 Kotlin 編程更輕鬆的重要工具。該庫具有語言的核心特性,例如算法問題、設計模式、數據處理以及與文件和數據流的操作。

本書中的示例提供了可立即執行的編碼解決方案。本書涵蓋了與數據處理、I/O 操作和集合轉換相關的各種主題。我們將介紹 Kotlin 中的有效設計模式,您將了解協程如何為 JavaScript 添加新功能。

通過閱讀本書的章節,您將學習如何實現乾淨、可重用的函數和包含默認實現的可擴展介面。在結尾的章節中,我們將提供有關函數式編程概念的示例,例如 lambda、monad、functor 和 Kotlin 作用域函數。

通過本書,您將能夠通過實現易於遵循的解決方案來解決 Kotlin 開發人員面臨的各種問題。

您將學到:

- 在使用案例中處理範圍、進展和序列
- 使用 Kotlin 擴展為現有類別添加新功能
- 了解 lambda、閉包和 monad 等元素
- 使用 Retrofit 和協程適配器構建 REST API 消費者
- 探索標準庫功能的好處
- 發現有用的提示和解決方案,使您的 Android 專案更好

本書適合對 Kotlin 基礎知識有所了解並希望了解更高級功能和概念的軟體開發人員,尤其是那些由 Kotlin 標準庫提供的功能。對於熟悉函數式編程範式和其他編程語言的經驗豐富的軟體開發人員,這本書也是理想的選擇,他們希望轉向 Kotlin。它還將幫助 Java 開發人員切換到 Kotlin,並將其集成到現有的 Java 虛擬機(JVM)專案中。

目錄:

1. 範圍、進展和序列的魅力
2. 設計具有表達力的函數和可調整介面
3. 使用 Kotlin 函數式編程功能塑造程式碼
4. 強大的數據處理
5. 基於 Kotlin 內建概念的優雅設計模式
6. 友好的 I/O 操作
7. 讓異步編程再次變得偉大
8. 使用 JUnit 和 Kotlin Mockito 進行單元測試
9. 雜項
