## Overview

This repository is a Java interview-preparation knowledge base, not an executable application. Its workflow is for a candidate to use the preparation guidance, study interview-tested topics, and practice explaining concepts and projects. The README indexes the subject areas and recommends personal introductions, project preparation, pressure practice, and concise expression. The graph shows only those documented links; there are no source excerpts establishing runtime behavior or dependencies among topics.

Main entry points: [`README.md`](https://github.com/xbox1994/java-interview/blob/master/README.md) (Preparation Guide), [`MD/Java基础-JVM原理.md`](https://github.com/xbox1994/java-interview/blob/master/MD/Java%E5%9F%BA%E7%A1%80-JVM%E5%8E%9F%E7%90%86.md) (JVM), [`MD/Java基础-集合.md`](https://github.com/xbox1994/java-interview/blob/master/MD/Java%E5%9F%BA%E7%A1%80-%E9%9B%86%E5%90%88.md) (Collections), [`MD/Java基础-多线程.md`](https://github.com/xbox1994/java-interview/blob/master/MD/Java%E5%9F%BA%E7%A1%80-%E5%A4%9A%E7%BA%BF%E7%A8%8B.md) (Multithreading)
