build\n```\n\n## List of packages\n\n- [annotation](src/main/java/by/andd3dfx/annotation)\n- [cache](src/main/java/by/andd3dfx/cache)\n- [collections](src/main/java/by/andd3dfx/collections)\n- [common](src/main/java/by/andd3dfx/common) (some uncategorized stuff)\n- [core](src/main/java/by/andd3dfx/core)\n- [dynamic](src/main/java/by/andd3dfx/dynamic)\n- [iterators](src/main/java/by/andd3dfx/iterators)\n- [jvm](src/main/java/by/andd3dfx/jvm)\n- [multithreading](src/main/java/by/andd3dfx/multithreading)\n- [numeric](src/main/java/by/andd3dfx/numeric)\n- [parser](src/main/java/by/andd3dfx/parser)\n- [proxy](src/main/java/by/andd3dfx/proxy)\n- [recursion](src/main/java/by/andd3dfx/recursion)\n-

[tests](src/test/java/by/andd3dfx); they contain some code which describes implementation in a natural\nway.\n\n## SQL-related stuff\n\n[SQL folder](sql/README.md) contains tasks which require writing SQL queries to solve them.\nCheck appropriate [video](https://youtu.be/GjDF_LdwYHU) on YouTube\n\n## Coding interview materials\n\nThe [interview-materials](interview-materials) folder contains some\nnotes about interview preparation and useful links.\nWe can perceive materials in this folder as project backlog or \"box with other stuff\"\n\n## Appendix. Verbal interview materials\n\nCheck [java-interview-faq-n-answers repo](https://github.com/andrei-punko/java-interview-faq-n-answers) to get materials for preparation to Java\nverbal interview\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fandrei-punko%2Fjava-interview-coding","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fandrei-punko%2Fjava-interview-coding","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fandrei-punko%2Fjava-interview-coding/lists"}
