Introduction

This repository is intended to help developers, students, and engineers understand and implement Low-Level Design concepts, emphasizing Object-Oriented Programming (OOP) and design patterns, using Java as the programming language.

Design Principles

We adhere to key OOP and software design principles, including:

• SOLID Principles
• DRY (Don’t Repeat Yourself)
• KISS (Keep It Simple, Stupid)
• YAGNI (You Aren’t Gonna Need It)

Design Patterns

In this repository, you will find Java implementations of various design patterns like:

• Creational Patterns (e.g., Singleton, Factory)
• Structural Patterns (e.g., Adapter, Facade)
• Behavioral Patterns (e.g., Observer, Strategy)

Implemented Systems

Here are some system design examples and solutions included in the repository, implemented in Java:

• Ride-Sharing System
• Hotel Booking System
• Food Delivery System
• Parking Lot System
