## What it is
A set of Chinese-language reading notes for the book 'Understanding the JVM' (深入理解 Java 虚拟机, 2nd edition), organized into memory management, bytecode execution, performance monitoring, and JIT optimization. The README acts as a searchable knowledge tree linking to detailed markdown notes on each JVM topic.

## Use cases
- learn how the JVM manages memory and garbage collection
- review JVM internals before an interview
- understand class loading and bytecode execution
- study JVM performance monitoring and tuning
- prepare for Java virtual machine exam-style self-testing

## When to choose
- you want structured notes on JVM internals in Chinese
- you are studying 'Understanding the JVM' and want organized summaries
- you need a quick-reference tree for GC, class loading, or JIT topics

## When to avoid
- you need official JVM documentation or specs
- you want runnable code or tools rather than notes
- you need English-language material

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation
- domain: tutorials, programming-languages, developer-tools
- platform: jvm
- tags: jvm, reading-notes, garbage-collection, class-loading, jit, chinese, study-notes
