## What it is
A companion code and notes repository for the free Low-Level Design (LLD) System Design playlist by Coder Army on YouTube. It contains Java implementations of LLD problems and concepts covered in the course.

## Use cases
- learn low-level design in Java
- prepare for system design LLD interview rounds
- find reference implementations of LLD problems like parking lot or LRU cache
- follow along with a free LLD video course
- practice object-oriented design patterns

## When to choose
- you are watching the Coder Army LLD playlist and want the accompanying code
- you want free Java examples of common LLD interview problems
- you are a beginner learning object-oriented design and design patterns

## When to avoid
- you need a production-ready LLD library or framework
- you want course material in a language other than Java
- you need a formally licensed codebase for commercial reuse (no license is provided)

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools
- domain: developer-tools, tutorials, education
- platform: jvm
- tags: low-level-design, system-design, interview-preparation, design-patterns, object-oriented-design, course-notes, java
