This module explores how classical design patterns have evolved to leverage modern Java features. You will learn to implement essential design patterns using functional interfaces, lambda expressions, and streams while understanding each pattern's practical applications and limitations. Through hands-on labs and guided exercises, you will gain proficiency in recognizing when and how to apply design patterns to solve common software engineering challenges.

This module provides a comprehensive exploration of modern Java testing frameworks and methodologies. You will understand test-driven development (TDD), learn JUnit 5 features, learn to write expressive assertions with AssertJ, and practice TDD techniques. Advanced topics include effective mocking strategies, property-based testing, and integration testing approaches for microservices architectures. Through practical labs, you will develop the skills to create maintainable, robust test suites that ensure code quality and reliability.

This module focuses on modern approaches to packaging and deploying Java applications in both traditional and cloud environments. You will learn to leverage Java modules, configure Maven builds, and implement Docker containerization strategies optimized for Java applications. The module covers security considerations in dependency management, Kubernetes deployment approaches, and CI/CD pipeline implementation. Through hands-on exercises, you will gain practical experience with deployment techniques relevant to enterprise Java development.

In this final module, you’ll complete a shareable project where you will create a command-line inventory management system that incorporates the design patterns, testing practices, and deployment techniques learned throughout the course. You’ll also demonstrate your ability to containerize a Java application using Docker during a graded project. Your final task is to complete the course-level final quiz.
