Название: On Java 8 Автор: Bruce Eckel Издательство: MindView LLC Жанр: Программирование Год издания: 2017 Страниц: 3402 ISBN: 978-0-9818725-2-0 Язык: Английский Формат: pdf/epub Размер: 26 Мб
" This book teaches the most modern form of Java programming using the features in the 8th version of that language.
My previous Java book, Thinking in Java, 4th Edition (Prentice Hall 2006), is still useful for programming in Java 5, the version of the language used for Android programming. But especially with the advent of Java 8, the language has changed significantly enough that new Java code feels and reads differently. This justified the two-year effort of creating a new book.
On Java 8 is designed for someone with a basic foundation in programming. For beginners, web sites like Code.org and Khan Academy can provide at least some of that background, along with the Thinking in C seminar freely available at the OnJava8 Site. "
