This repository contains some of my mini projects completed during my undergraduate studies at SRM University. These projects showcase my practical skills, creativity, and dedication to hands-on learning.

User Customized Clothes Recommend System

A sleek, colourful Java Swing demo that implements the Memento design pattern to provide reliable multi-step undo/redo for a text editor.

A colourful Java Swing demo that illustrates the Visitor design pattern for a shopping cart. Different item types (Book, Electronics, Clothing) accept visitors that perform operations such as printing details, totaling prices, and applying discounts — without modifying the item classes themselves.

A hands-on collection of foundational Object-Oriented Design Patterns implemented in Java.

Make beautiful clones, fast. A compact, delightful Java Swing app that demonstrates the Prototype design pattern through an interactive drawing studio.

A sleek Java Swing desktop application showcasing the Builder Pattern, complete with live preview and instant configuration output.

Flyweight-Urban-Traffic-Simulator — a colourful, real-time 2D/3D-style demo (single-file Java Swing) that demonstrates the Flyweight Design Pattern to efficiently simulate thousands of vehicles without duplicating heavy geometry/texture data.

TC Text Editor is a sleek, high-performance Java Swing application showcasing the Flyweight Design Pattern. Built with clean code and Maven, it delivers an intuitive UI and extreme memory efficiency.

A polished Java Swing desktop app demonstrating the Chain of Responsibility pattern for real-time transaction validation.

A sleek, modular Java Swing desktop messenger that sends Text, Image, or Audio messages via Email, WhatsApp, or SMS — all powered by the Bridge Pattern.

CalcPro is a colourful, math-inclined single-file Java demo that implements the Interpreter Design Pattern to parse and evaluate custom formulas like ADD(5, 10), MULTIPLY(ADD(2,3),4) and DIVIDE(SUBTRACT(20,4),2).

A sleek, dark-themed Java Swing code editor with robust Undo/Redo powered by the Memento Pattern.

Compute areas cleanly — without changing your shape classes. A lightweight, educational, and visually delightful Java Swing application demonstrating the Visitor design pattern to compute areas for multiple shape types (Circle, Square, Triangle) while keeping code open for extension.

Customize your hero’s abilities, apply modular upgrades, and see real-time changes in stats and sprites!

A colourful, educational Java Swing demo that parses integer expressions (infix) containing + and -, builds an AST using the Interpreter pattern, evaluates step-by-step, and displays tokens, RPN, evaluation steps and the final result.

A colourful Java Swing demo that demonstrates the Prototype design pattern. Create an original player, clone it multiple times to experiment with ‘what-if’ scenarios, and manipulate clones independently without affecting the original.
