Java Interview

This is a structured collection of interview preparation materials organized as a question bank covering multiple technology domains. The content is stored as plain Markdown files arranged in a topic-based directory hierarchy, delivered as static HTML without any JavaScript framework or build pipeline.

The material focuses on Java ecosystem topics including core language features, collections, multithreading, JVM internals, Java 8 features, I/O, serialization, OOP principles, JDBC, servlets and JSP, logging, reactive programming, and testing. It also covers relational databases and SQL, web development fundamentals including HTML, CSS, HTTP, and web servers, as well as design patterns, Apache Kafka, UML, and XML.

Each technology area is divided into independent modules with discrete question-and-answer units, allowing focused study on specific topics. The content is pre-written and static, requiring no server-side processing or dynamic generation.
