Java coding problems: become an expert Java programmer by solving modern real-world problems (Second edition.)

Stay on top of new Java features and find efficient solutions for your programming woes

Key Features

• Solve Java programming challenges and get interview-ready with the power of modern Java 20
• Test your Java skills using language features, algorithms, data structures, and design patterns
• Explore tons of examples meant to help you accommodate JDK 12 to JDK 20

Book Description

The super-fast evolution of the JDK between versions 12 and 20 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.

Jave 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's the best solution for a certain problem.

There are more than 200 carefully selected problems in this book, 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.
