Athena Java

Athena is a Chinese-language Java backend knowledge map designed to help beginners build a broad and organized technical foundation. It collects articles, interview notes, tutorials, summaries, diagrams, and practical examples rather than providing one executable application. Core coverage includes Java fundamentals, collections, concurrency, the JVM, Spring, MyBatis, Hibernate, JDBC, MySQL, Redis, and message queues. It also introduces data structures, algorithms, Linux, computer networks, operating systems, web development, security, Docker, and development tools. Several sections frame concepts as interview conversations and include resume and job-preparation guidance. Project examples cover common web systems, permissions, shopping carts, file handling, and messaging platforms. The repository functions as a structured study index for students preparing for Java backend work and technical interviews.
