Introduction:
Welcome to Part 6 of our Low-Level Design (LLD) series. In this article, we will design a Parking Lot System – a common real-world problem often discussed in system design interviews. This guide will walk you through the class diagrams, class relationships, UML diagrams, database schemas, and Java code examples required to implement a fully functional parking lot system.
This is a crucial concept for interviews as it tests your understanding of object-oriented design, system relationships, and how to handle edge cases. By the end of this article, you’ll have a strong grasp of how to approach parking lot design questions in interviews.
