Java continues to grow and evolve, and this cookbook continues to evolve in tandem. With this guide, you’ll get up to speed right away with hundreds of hands-on recipes across a broad range of Java topics. You’ll learn useful techniques for everything from string handling and functional programming to network communication.

Each recipe includes self-contained code solutions that you can freely use, along with a discussion of how and why they work. If you’re familiar with Java basics, this cookbook will bolster your knowledge of the language and its many recent changes, including how to apply them in your day-to-day development. This updated edition covers changes through Java 12 and parts of 13 and 14.

Recipes include:

Methods for compiling, running, and debugging
Packaging Java classes and building applications
Manipulating, comparing, and rearranging text
Regular expressions for string and pattern matching
Handling numbers, dates, and times
Structuring data with collections, arrays, and other types
Object-oriented and functional programming techniques
Input/output, directory, and filesystem operations
Network programming on both client and server
Processing JSON for data interchange
Multithreading and concurrency
Using Java in big data applications
Interfacing Java with other languages
