OOP Basics

Dive into the core principles of OOP with a focus on foundational concepts. Explore the essence of object-oriented programming, understanding classes and objects, the significance of abstract keywords and classes, and the role of interfaces in Java. This section provides a solid foundation for building on the more advanced concepts.

OOP Core Principles - Inheritance, Polymorphism, Encapsulation and Abstraction

Delve deeper into the core principles that shape OOP. Master inheritance, a powerful mechanism for code reusability and hierarchy. Understand polymorphism, enabling objects to take on different forms based on their class. Learn about encapsulation, protecting data and methods within classes, and grasp the concept of abstraction, simplifying complex systems through interfaces and abstract classes. This section empowers you to create well-structured and maintainable code.

SOLID Principles

Embrace SOLID principles for writing clean, modular, and easily maintainable code. Explore each principle in detail: Single Responsibility Principle, Open/Closed Principle, Liskov Substitution Principle, Interface Segregation Principle, and Dependency Inversion Principle. This section is a key to crafting high-quality software architectures.

PRACTICE: Coding exercises to practice SOLID principles

Put your understanding of SOLID principles into action with practical coding exercises. Work through challenges involving user registration, shape refactoring, square and rectangle manipulation, worker optimization, and car-engine design. This section is your playground for applying SOLID principles and refining your coding skills.

Methods

Learn the intricacies of methods in Java, a fundamental building block of OOP. Explore parameter passing mechanisms, dive into recursive methods, and understand variable-length arguments. Gain hands-on experience through coding exercises that involve array manipulation, string processing, and algorithm implementation. Master essential coding techniques with a focus on problem-solving.

===== OOP: Interview Preparation =====

Prepare for your next OOP interview with confidence. This section dives into the most common OOP interview questions and answers, helping you showcase your understanding of key concepts. Learn how to approach interview scenarios and effectively communicate your knowledge.

Practice: EXAM OOP & Object-Oriented e-Commerce console applications

Apply your OOP knowledge in a real-world context by building an e-commerce backend application. Work through practical coding challenges involving payment and transaction processing, book management, presents management, and the development of a complete e-commerce backend system. This section provides hands-on experience in building robust and practical systems.

Object-oriented Architecture, Clean Code Design (Advanced)

Go beyond the basics of OOP with this section exploring advanced concepts in object-oriented architecture and clean code design. Dive into the principles of coupling and cohesion, the significance of the Tell, Don't Ask Principle, and explore data structures within the context of OOP. Learn about the Law of Demeter and key principles like KISS (Keep It Simple, Stupid), YAGNI (You Ain't Gonna Need It), and DRY (Don't Repeat Yourself). Understand how to create well-structured and maintainable codebases using effective packaging principles.

GoF Design Patterns of Software Architecture in OOP

Explore the world of Gang of Four (GoF) design patterns, widely recognized solutions to common software design problems. This section provides a comprehensive overview of creational, structural, and behavioral patterns. Learn how to apply these patterns effectively to build flexible, scalable, and maintainable software architectures.

===== Design Patterns: Interview Questions =====

Prepare for interview questions related to design patterns. This section delves into the most common questions about OOP and design patterns, equipping you with the knowledge and confidence to ace your next interview.

UML Introduction

Uncover the power of Unified Modeling Language (UML), a visual modeling language used to design and document software systems. Learn why UML is essential for effective communication and collaboration, understand its core concepts, and gain an introductory overview of UML diagrams.

Behavioral Diagrams

Delve into the world of behavioral diagrams, which depict how a system behaves over time. Explore use case diagrams, sequence diagrams, activity diagrams, state machine diagrams, communication diagrams, timing diagrams, and interaction overview diagrams. Learn how to use these diagrams to model system interactions and workflows.

Structural Diagrams

Master structural diagrams, used to represent the static structure of a system. Explore class diagrams, object diagrams, component diagrams, package diagrams, deployment diagrams, composite structure diagrams, and profile diagrams. Learn how to use these diagrams to visualize the relationships between classes, components, and systems.
