Описание: Get an in-depth introduction to the Go programming language and its associated standard runtime libraries. This book is targeted towards programmers that already know the Java programming language and uses that Java knowledge to direct the learning of Go. You will get a deep understanding of the Go language and obtain a good introduction to the extensive Go standard libraries.

This book teaches Go through clear descriptions of Go features, contrasting them with similar Java features and via providing extensive code examples. After reading this book you will be knowledgeable enough about Go and its libraries to begin doing effective programming using the Go language.

Go for Java Programmers is structured more like a tutorial than a reference document. It covers key features of Go, but not every little detail as a reference might. Its goal is to get you competent enough in Go and its runtime that you can begin to effectively write Go programs.

Получите подробное введение в язык программирования Go и связанные с ним стандартные библиотеки времени выполнения. Эта книга предназначена для программистов, которые уже знают язык программирования Java и используют эти знания Java для обучения Go. Вы получите глубокое понимание языка Go и получите хорошее представление об обширных стандартных библиотеках Go.

Эта книга учит Go с помощью четких описаний функций Go, сравнивая их с аналогичными функциями Java и предоставляя обширные примеры кода. Прочитав эту книгу, вы будете достаточно хорошо осведомлены о Go и его библиотеках, чтобы начать эффективное программирование с использованием языка Go.

Структура этой книги больше похожа на учебник, чем на справочный документ. Он охватывает ключевые функции Go, но не все мелкие детали, как может быть в справочнике. Его цель — сделать вас достаточно компетентными в Go и его среде выполнения, чтобы вы могли начать эффективно писать программы на Go.
