Java: Design Patterns, Testing and Deployment

Premium
IntermediateCourse

In this course, you'll learn how to design flexible Java applications using factory, strategy, and observer patterns to solve real-world problems. You'll discover how to apply modern Java 17+ features such as lambdas, functional interfaces, and modular architecture to write clean, maintainable code. Then learn how to build strong test suites for test-driven development (TDD) using JUnit 5, AssertJ, and Mockito to catch bugs early and help ensure reliability. Then, explore how you can deploy applications to production using Docker, Maven, and CI/CD pipelines.

About this Course
Java is one of the most in-demand programming languages, powering 3 billion devices and ranking consistently in the top 3 of developer surveys. Companies worldwide seek developers who can implement scalable architecture, rigorous testing, and cloud-ready deployment. This intermediate course bridges the gap between basic Java knowledge and the advanced, enterprise-level skills employers value most. 
 
During the course, you’ll develop the expertise to design maintainable systems, write high-quality tests, and deploy production-ready applications—skills critical for competitive job market. 
 
 You’ll start with Gang of Four patterns updated for Java 17+, learn functional interfaces and lambdas as building blocks, and apply patterns like such as Factory, Strategy, Builder, and Observer. Next, you’ll dive into JUnit fundamentals, expressive tests with AssertJ, mocking with Mockito, and integration testing strategies. Then finally, you’ll master deployment using JLink, Maven, Docker, Kubernetes, and CI/CD pipelines, with security and performance best practices included.  

As you learn, you’ll get hands-on in labs and projects where you’ll create singleton classes, build factory implementations, develop TDD-driven utilities, and containerize applications. The final project—an Inventory Management Solution—integrates design, testing, and deployment skills into a showcase-worthy portfolio piece.  

Other practical work includes: 

  • Identifying and implementing design patterns for real-world Java applications. 
  • Applying advanced testing strategies, from unit testing with JUnit to integration testing with TestContainers. 
  • Deploying secure, optimized Java applications using Maven, Docker, Kubernetes, and CI/CD pipelines. 
 
If you’re looking to strengthen your resume with advanced Java skills, demonstrate industry-relevant competencies to employers, and position yourself for Java developer and backend engineering roles, enroll now and power up your Java career! 

Prerequisites 
This is an intermediate-level course. You should have foundational Java programming skills, object-oriented programming knowledge, basic Git and GitHub experience, and familiarity with containerization concepts such as Docker and Kubernetes. No prior design pattern experience is required.
