## What it is
A curated repository listing 100 classic Java-related technical books as PDF downloads (via Baidu cloud links), covering topics from beginner Java to JVM internals, Spring, MySQL, and Hadoop. It is a reading-resource index rather than software, and also links to helpful tools like OCRmyPDF.

## Use cases
- find free Java programming books in PDF
- download JVM internals ebooks
- get Spring and Spring Cloud book PDFs
- locate MySQL and Hadoop reference books
- build a Java learning reading list from beginner to architect
- find Chinese-language Java technical books

## When to choose
- you want a curated, stage-by-stage Java reading list
- you prefer reading full classic books over scattered tutorials
- you need Chinese editions of Java, JVM, Spring, MySQL, or Hadoop books

## When to avoid
- you need runnable code or a software library
- you require legally licensed or officially distributed ebooks
- you need content guaranteed to stay available, since cloud links may expire

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, pdf
- domain: education, programming-languages, developer-tools, databases, big-data
- platform: cross-platform
- tags: java-books, pdf-ebooks, curated-list, baidu-pan-links, jvm, mysql, hadoop, spring, chinese-language
