Software Modeling and Design Lab

This repository contains Java-based examples from the Software Modeling and Design course, covering design patterns, SOLID principles, and software design best practices. Organized into weekly labs and preparation modules, it includes implementations of creational, structural, and behavioral patterns, along with functional programming examples in JavaScript.

📌 Topics Covered

Weekly Labs

Week 1: Object-Oriented Basics & Principles

• Composition vs Inheritance (Example01BeforeComposition, Example01AfterComposition)
• Single Responsibility Principle (SRP) (Example02ViolationOfSingleResponsibility, Example02SolutionUsingSingleResponsibility)
• Inversion of Control (IoC) & Dependency Injection (DI) (Example03BeforeIoC, Example03AfterIoC)
• Filter Pattern (Example04)

Week 2: SOLID Principles

• Liskov Substitution Principle (LSP) (Example01Before, Example01After)
• Interface Segregation Principle (ISP) (Example02Before, Example02After)
• Dependency Inversion Principle (DIP) (Example03Before, Example03After)
• Singleton Pattern & Database Connection (Example04Before, Example04After)

Week 3: Creational Design Patterns

• Factory Pattern (Example01, Example02MethodParameter, Example02SeparateMethods)
• Prototype Pattern (Example03)
• Connection Pool (Singleton + Prototype) (Example04)

Week 4: Structural Design Patterns

• Adapter Pattern (example01: Payment System Integration)
• Bridge Pattern (example02: Webpage Localization)

Week 5: Advanced Design Patterns

• Builder Pattern (example01: Vehicle Configuration)
• Composite & Flyweight Patterns (example02: Shape Rendering)
• Decorator Pattern with Factories (example03: Car Customization)

Week 11: Behavioral Patterns & Functional Programming

• State Pattern (example01: Task Workflow)
• Memento Pattern (example02: Text Editor History)
• Functional Programming Examples (functional_programming_examples in JavaScript)
