Object Oriented Designs UML Diagram

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.

NTU Computer Science - CZ2002 Object Oriented Design Principles (OODP)

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

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

User Customized Clothes Recommend System

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

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.

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

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.

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 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.

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.

MelodyShare is a compact, colourful demo that uses the Flyweight design pattern to share heavy album data (artwork, artist, album meta) across many Song instances. This reduces memory usage while allowing thousands of simultaneous plays.
