When will I have access to the lectures and assignments?

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

What will I get if I subscribe to this Specialization?

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

Is financial aid available?

Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.

"Tired of ""God Classes"" and spaghetti code in your Java ML projects? This course, ""Enhance Java ML Design with SOLID Principles,"" is for senior developers and architects ready to build resilient software. The secret to reliable systems is accepting that requirements always evolve. Master the S.O.L.I.D. principles to write code that embraces future changes with minimal impact.

This course is designed for senior Java developers and architects with at least 6 months of hands-on experience in Java programming and basic knowledge of machine learning. If you're ready to tackle "God Classes" and spaghetti code, and want to optimize your Java ML projects with SOLID principles for scalability, maintainability, and flexibility, this course is for you. To get the most out of this course, learners should have at least 6 months of hands-on experience with Java programming, including a solid understanding of object-oriented programming (OOP) concepts such as classes, interfaces, and abstract classes. Additionally, a basic knowledge of machine learning (ML) concepts is essential to fully grasp how to apply SOLID principles to Java ML projects. By the end of this course, you’ve unlocked the power of SOLID principles to create flexible, scalable, and maintainable Java ML systems. You now have the tools to refactor messy code, design modular components, and evaluate trade-offs between performance and design. With your newfound expertise in SOLID, Maven, Gradle, and best practices, you're ready to build production-ready machine learning applications that can evolve with ease. Keep applying these principles, and your code will become more reliable and adaptable with every project. Best of luck as you continue to level up your skills in Java and machine learning!

Module details

In this module, learners will start with a messy "ModelHandler" class that violates multiple SOLID principles. Learners will learn to identify code smells, understand the business impact of poor design, and systematically refactor using SRP and OCP. By the end, learners will have transformed a monolithic class into a clean, modular system that's ready for future changes.

Hands-On-Learning: Refactor a Monolithic Class Using Single Responsibility Principle 30 minutes

This lesson focuses on creating truly flexible ML systems. You'll learn how LSP ensures your abstractions work correctly with any implementation, while DIP helps you build systems that depend on abstractions rather than concrete implementations. We'll show how to swap out different ML models and data sources without breaking your application.

In this lesson, you'll learn to design clean, focused interfaces that don't force clients to depend on methods they don't use. We'll also dive into practical project management with Maven and Gradle, showing how proper build tool configuration supports clean architecture and manages the complex dependency trees common in ML projects.

This final lesson brings everything together by examining real-world scenarios where strict adherence to SOLID principles might conflict with practical concerns like performance, simplicity, or time constraints. You'll develop a framework for making pragmatic design decisions and learn when to prioritize certain principles over others.
