An Essential Guide to the Core Language and Libraries--Updated for Java 21
Modern Java introduces major enhancements that impact the core language and APIs at the heart of the Java platform. Many old Java idioms are no longer needed, and new features and programming paradigms can make you far more effective. However, navigating these changes can be challenging.
Core Java for the Impatient, Fourth Edition, is a complete guide that reflects all changes through Java SE 21, Oracle''s latest Long-Term Support (LTS) release. Written by Cay S. Horstmann--author of the classic two-volume Core Java--this concise tutorial offers a faster, easier pathway for learning modern Java.
Horstmann covers everything working developers need to know, including the powerful concepts of lambda expressions and streams, modern constructs such as records and sealed classes, and sophisticated concurrent programming techniques. Given the size and scope of Java 21, there''s plenty to cover.
