## Overview

This is a Java learning repository, not one integrated application: learners run independent examples and problem solutions to observe algorithmic results or OOP and collections behavior. Its principal workflow is selecting a topic, running an example, and viewing its output; the string exercises additionally read console input. The README documents complexity analysis, but that material is absent from the supplied file tree, so it is not represented as a source component. Links between independent examples are omitted; the graph reflects the README and sampled source.

Main entry points: [`src/collections/ECommerceEngine.java`](https://github.com/iamkrish-0708/java-dsa-mastery/blob/main/src/collections/ECommerceEngine.java) (E-commerce Demo), [`src/strings`](https://github.com/iamkrish-0708/java-dsa-mastery/tree/main/src/strings) (String Problems), [`src/basics`](https://github.com/iamkrish-0708/java-dsa-mastery/tree/main/src/basics) (Basic Math), [`src/arrayQuestionSolving`](https://github.com/iamkrish-0708/java-dsa-mastery/tree/main/src/arrayQuestionSolving) (Array Problems)
