Book DescriptionThe 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.What you will learn
