About the Book

The Java and Spring Boot Interview Compendium is a structured technical interview reference for developers working with modern Java and Spring-based applications.

The content is organized around the core language, runtime, concurrency, persistence, API, architecture, and framework topics that experienced engineers are commonly expected to explain in interviews. Each section combines concise explanations with practical examples so readers can review both foundational concepts and real implementation tradeoffs.

The book is designed to help developers revisit important Java and Spring Boot concepts in a practical way, with a strong focus on modern language features, framework usage, and production-oriented design decisions.
