Core Java for the Impatient (Paperback)

Cay S. Horstmann



The release of Java SE 8 introduced significant enhancements that impact the Core Java technologies and APIs at the heart of the Java platform. Many old Java idioms are no longer required and new features like lambda expressions will increase programmer productivity, but navigating these changes can be challenging.


Core Java® for the Impatient is a complete but concise guide to Java SE 8. Written by Cay Horstmann—the author of Java SE 8 for the Really Impatient and Core Java™, the classic, two-volume introduction to the Java language—this indispensable new tutorial offers a faster, easier pathway for learning the language and libraries. Given the size of the language and the scope of the new features introduced in Java SE 8, there’s plenty of material to cover, but it’s presented in small chunks organized for quick access and easy understanding.


If you’re an experienced programmer, Horstmann’s practical insights and sample code will help you quickly take advantage of lambda expressions (closures), streams, and other Java language and platform improvements. Horstmann covers everything developers need to know about modern Java, including 

  • Crisp and effective coverage of lambda expressions, enabling you to express actions with a concise syntax
  • A thorough introduction to the new streams API, which makes working with data far more flexible and efficient
  • A treatment of concurrent programming that encourages you to design your programs in terms of cooperating tasks instead of low-level threads and locks
  • Up-to-date coverage of new libraries like Date and Time
  • Other new features that will be especially valuable for server-side or mobile programmers 

Whether you are just getting started with modern Java or are an experienced developer, this guide will be invaluable for anyone who wants to write tomorrow’s most robust, efficient, and secure Java code.


Java SE 8的發布引入了對Java平台核心技術和API的重大增強。許多舊的Java習語不再需要,而新功能如lambda表達式將提高程式設計師的生產力,但要理解這些變化可能是具有挑戰性的。

《Core Java® for the Impatient》是一本完整而簡潔的Java SE 8指南。由Cay Horstmann撰寫,他是《Java SE 8 for the Really Impatient》和《Core Java®》這兩本經典的Java語言入門書的作者,這本不可或缺的新教程提供了一條更快、更簡單的學習語言和庫的途徑。考慮到Java SE 8的語言規模和引入的新功能的範圍,有很多內容需要涵蓋,但它以小塊組織,以便快速訪問和易於理解。


- 簡潔而有效的lambda表達式覆蓋範圍,使您能夠以簡潔的語法表達操作
- 對新的流API的全面介紹,使處理數據更靈活、高效
- 一種鼓勵您以合作任務而不是低級線程和鎖來設計程序的並發編程方法
- 對新的庫(如日期和時間)的最新覆蓋範圍
- 其他對服務器端或移動端程式設計師特別有價值的新功能
