Java 9及其新特性豐富了Java語言的內(nèi)涵,這是開發(fā)者們*廣泛使用的語言之一。Java9通過與Jigsaw集成,從而特別強(qiáng)調(diào)了模塊化。本書是你精通該語言的一站式指南。
你可以從中獲得Java 9相關(guān)的概覽和新特性解釋。并了解新API和增強(qiáng)部分的重要性。某些Java 9的新特性是開創(chuàng)性的,如果是有經(jīng)驗(yàn)的程序員,你將能夠把企業(yè)級(jí)應(yīng)用變得更精煉。愛德華·拉維耶里、皮特·維哈斯著的《精通Java9(影印版)(英文版)》提供了在Java平臺(tái)開發(fā)上應(yīng)用Java 9相關(guān)新知識(shí)以及更多信息的實(shí)用指南。本書有助于提高生產(chǎn)力,讓你的應(yīng)用變得更快。通過學(xué)習(xí)Java*佳實(shí)踐,你將成為組織里的百曉生。
學(xué)完此書,你不僅能知道Java 9的重要概念,也會(huì)對(duì)使用這門語言進(jìn)行編程的重要方面具備精深理解。
