Java continues to grow and evolve, and this Cookbook continues to evolve in tandem. This book helps to get you 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 are familiar with the basics of the Java language, this cookbook will bolster your knowledge of the language in general and its many recent changes and how to apply them in your day-to-day development.Recipes include:Methods for compiling, running, and debugging“Packaging” Java classes and building applicationsManipulating, comparing, and rearranging textRegular expressions for string- and pattern-matchingHandling numbers, dates, and timesStructuring data with collections, arrays, and other typesObject-oriented and functional programming techniquesInput/Output, Directory and filesystem operationsNetwork programming on both client and serverProcessing JSON for data interchangeMultithreading and concurrencyUsing Java in Big Data applicationsInterfacing Java with other languages------------------The 4th Edition of this book has been updated to cover changes through Java 12 and includes new recipes for Big Data and data science.

The super-fast evolution of the JDK between versions 8 and 12 has increased the learning curve of modern Java, therefore has increased the time needed for placing developers in the Plateau of Productivity. Its new features and concepts can be adopted to solve a variety of modern-day problems. This book enables you to adopt an objective approach to common problems by explaining the correct practices and decisions with respect to complexity, performance, readability, and more.Java Coding Problems will help you complete your daily tasks and meet deadlines. You can count on the 300 applications containing 1,000 examples in this book to cover the common and fundamental areas of interest: strings, numbers, arrays, collections, data structures, date and time, immutability, type inference, Optional, Java I/O, Java Reflection, functional programming, concurrency and the HTTP
