About this course

Transitioning from basic scripts to robust, scalable software requires a deep understanding of how objects interact. This course provides a clear path for beginners to master the architectural patterns used by professional developers every day to build reliable systems. You will transform from a novice coder into someone who can design complex software using Java. By focusing on the logic behind object interactions, you will learn to write clean, maintainable code that follows industry-standard design principles, preparing you for the demands of modern backend development. What you'll learn: - Learn the foundational pillars of OOP: encapsulation, inheritance, polymorphism, and abstraction - Understand SOLID principles to create flexible and scalable software architectures - Build the core logic for an online store backend, including user management and transaction processing - Apply modern Java features like Records to simplify data handling and improve code clarity - Practice writing clean code and implementing basic testing logic to ensure system reliability - Design domain-specific class structures that map to real-world business requirements The course begins with essential terminology and the conceptual shift from procedural to object-oriented thinking. You will then progress through detailed written explanations and code-based scenarios to implement a sophisticated backend system step-by-step. This course is designed for beginners with a basic grasp of programming syntax who want to learn professional software design. No prior experience with object-oriented architecture is required. Start your journey into professional software architecture today.
