Description

The super-fast evolution of the JDK between versions 12 and 21 has made the learning curve of modern Java steeper, and increased the time needed to learn it. This book will make your learning journey quicker and increase your willingness to try Java’s new features by explaining the correct practices and decisions related to complexity, performance, readability, and more. Java Coding Problems takes you through Java’s latest features but doesn’t always advocate the use of new solutions — instead, it focuses on revealing the trade-offs involved in deciding what the best solution is for a certain problem. There are more than two hundred brand new and carefully selected problems in this second edition, chosen to highlight and cover the core everyday challenges of a Java programmer. Apart from providing a comprehensive compendium of problem solutions based on real-world examples, this book will also give you the confidence to answer questions relating to matching particular streams and methods to various problems. By the end of this book you will have gained a strong understanding of Java’s new features and have the confidence to develop and choose the right solutions to your problems.

It's quite some time that I have came across an exhaustive book on usage of java focusing on various modern and real-world problems. Here are some of the initial feedback that I have on the book and I am blown by the exhaustiveness and clear explanations.- The reference book provides clear and simple code samples of the problem described.- Covers some of very niche (advanced) things like stages of GC and the epoch cycles.- Consists of a dedicated chapter for Socket and consists of various examples of the usage of Simple Web Server (SWS) for some of the real world scenarios.- For someone coming from Object oriented styled programming paradigm, the book has well explained examples of functional programming in general.The book looks very promising to build a deeper level insight on Java Programming.

I really like this book. I am a Senior Java engineer and think It will be useful for any Java fan of any level. Book is built like problem-solving that is very actual for nowadays comparing and explanations features from the very first Java versions till new features of Java 21. Besides code examples really good, clear structure and running without any problem, there are examples also with benchmark. It is easy to check theory by your own for me this is very important.The most I liked explanations of project Loom, Virtual threads because it is a completely new theme for me but after book I'm ready to use it in a project.Also found new useful information and problem solving for strings, switch, collections, records.

Just started diving into Java and this book became my coding buddy! Over 250 problems might seem scary at first, but they're like a step-by-step guide. You learn new stuff constantly without feeling overloaded. Plus, it covers all the latest Java features, which feels pretty cool. But my favorite part? It's not just about the answer, it teaches you how to approach problems strategically, thinking about clean and efficient code. Huge bonus for the explanations too, even the trickier concepts were clear. Feeling way more confident with Java thanks to this book! Definitely recommend it for anyone who wants to up their coding game.
