Java: Design Patterns, Testing, and Deployment

Overview

Ready to take your Java skills to the next level? This course bridges the gap between basic Java programming and enterprise-level software engineering. You’ll build valuable enterprise Java development skills founded on modern patterns and practices that make your resume stand out! During the course, you'll master design patterns using lambda expressions, implement Test-Driven Development (TDD) with JUnit 5 and Mockito, and deploy scalable applications using Docker and Kubernetes. In hands-on labs and real-world scenarios, you'll learn Gang of Four patterns modernized for Java 17+, comprehensive testing strategies, and cloud-native deployment approaches that top tech companies use daily. Plus, through a project-based approach, you’ll combine three critical enterprise skills: design pattern implementation, test-driven development, and containerization practices, building a complete inventory management system. A great addition to your portfolio that you can talk about in interviews! If you’re keen to build more advanced Java development skills employers need for Java developer roles, enroll today!

Syllabus

Modern Java Design Patterns

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.

Testing with Java

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.

Deployment with Java

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.

Final Project, Final Quiz, and Course Wrap-Up

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.
