- About the Authors
Automated code generation is rising, but the need for skilled software engineers is more critical than ever. Engineers must still understand, design, debug, and guide the systems they build. Modern Java continues to be one of the most reliable and widely used languages, capable of powering everything from small applications to large-scale enterprise systems.
This book follows a structured, step-by-step path and uses real-world scenarios to explain concepts beyond syntax. It begins with Java fundamentals, including IDE setup, versions, debugging, and object-oriented programming. It also explores building blocks such as exception handling, collections, and file management before moving to practical development. The book guides you through building CRUD applications from CLIs to GUIs. It also covers database operations using JDBC and ORM tools, automation tasks such as scheduling email processing, web scraping, API integration, and AI/ML services. It further introduces multithreading and building scalable applications using Spring Boot and Quarkus, followed by deployment.
By the end of this book, you will gain the skills and confidence to design and build real-world Java applications. You will also develop practical experience in automation, secure coding, API integration, deployment strategies, and modern DevOps practices.
