Getting Started

Prerequisites

• JDK 11 or later — verify with:

  java -version
  javac -version

No build tools or external libraries are required. Every project compiles with plain javac.

Clone

git clone https://github.com/Deepanshxsharma/myanatomy-java-stack.git
cd myanatomy-java-stack

Run a Project

Module 1 — Inventory Management System

cd "Module - 1/Inventory Management System"
javac *.java
java Main

Module 2 — Multi-Threaded File Processor

cd "Module - 2/MultiThreadedFileProcessor"
./run.sh          # macOS / Linux
run.bat           # Windows

See each project's README for detailed usage and design notes.

Concepts Covered

• Object-Oriented Programming — encapsulation, models, separation of concerns
• Collections Framework — List, Map, TreeMap, ArrayList
• File I/O — object serialization, buffered CSV reading, report writing
• Concurrency — thread pools, Callable, Future, graceful shutdown
• Design Patterns — Builder pattern for immutable configuration
• Functional Java — lambdas, method references, Stream API
• Input Validation — defensive parsing and error handling
