Java Precisely

Java Precisely, 3rd edition by Peter Sestoft, offers an updated and succinct reference for the Java programming language, focusing on version 8.0. Written with precision and clarity, this book is designed as a compact companion for both those who have learned Java from a standard textbook and practitioners looking to deepen their understanding of the language's finer points. The book provides a detailed overview of Java's key elements, from the core syntax and semantics to the essential components of its class libraries - including collections, input-output, stream processing, and the facilities for parallel programming. Its user-friendly structure is enhanced by an informal presentation that pairs clear general rules on one page with concrete examples on the opposite page, each example representing a valid fragment of Java code. This third edition also introduces new material on functional parallel processing of arrays, default and static interface methods, and a concise explanation of the memory model relevant to concurrent threads. Topics such as lambda expressions, method references, and advanced stream processing are covered, equipping readers with a thorough and up-to-date reference for modern Java programming.
