Hello guys, last week I have shared about the best books to learn design patterns in Java, and today, we’ll talk about design patterns and some of the best online courses to learn design patterns in Java from scratch. If you are wondering what is a design pattern and why Java developers should learn them? then let me give you a brief overview.

Design patterns are nothing but a tried and tested solution of common programming problems, for example, the creational design patterns deal with the problems of object creation.

They exist for a long time but made popular by famous Gang of four of Erich Gamma, John Vlissides, Ralph Johnson, and Richard Helm in their classic 1994 book Design Patterns: Elements of Reusable Object-Oriented Software, also known as GOF design patterns. This book documented 24 design patterns that are reusable to solve common programming problems.

The original book was written using C++ and Smalltalk as examples, but since then, the design pattern has been adopted by almost every programming language like Java, C#, PHP, and even programming language which is not strictly object-oriented like JavaScript.

The benefit of design patterns are immortal, you will find them in many frameworks, libraries, and in-built int eh programming language.

You probably use them on a daily basis even if you don’t realize they are there. For example, JDK uses several GOF design patterns like Decorator is used in IO classes, Strategy is used along with Comparable and Comparator, and so on.

The knowledge of OOP design principles and GOF design patterns are very important for Java developers because it enables them to write better code.

It is also important from the interview perspective, where interviewer often judges experienced Java developers with their knowledge of design patterns.

Top 7 Courses to Learn OOP Design Patterns in Java

I have been sharing a lot of programming resources recently e.g. free books and courses on Java, Python, Git, Eclipse, and DevOps tools like Jenkins and Maven. If you are new here you can find them by doing a quick search using Google’s custom search box at the top-right corner of the page.

Today, I’ll share some of the best online courses to learn Design patterns from scratch. These courses are not free but not very expensive either. You can buy them in the Udemy’s flash sale for just $10.99 and sometimes even lower with just $9.99.

I have already bought over 50 courses on Node JS, Spring, Kotlin, DevOps, BigData, Java 9, and Android on Udemy’s last sale.

Most of these courses will not only explain to you how these design patterns work and what problems they solved but also how to use them in the real world.

For example, I really like the example of using the Strategy pattern for designing a Payment system on Paulo Dichone’s Java Design Patterns MasterClass course.

Some of the courses also explain basic OOP design principles which are the basic building block of design patterns like SOLID principles like Single Responsibility principle, Open-closed design principle, Liskov Substitution, Inversion of control, and Dependency injection, etc.

Apart from these they also cover some of the less popular but still useful principles like Law of Demeter and Delegation principles.

1. Design Patterns in Java

This is one of the best courses to learn design patterns in Java. It not only covers the GOF patterns like Command, Decorator, Adapter, Strategy, Proxy, Chain of Responsibility, Interpreter end but also covers the famous SOLID design principles which form the basis of design patterns.

This is also a very hands-on course where the author will show you how to implement a particular design pattern live on IntelliJ IDEA.

Most demos are also a single-file, so you can also download the file attached to the lesson and run it in Intelli IDEA, Eclipse, NetBeans, or another IDE of your choice.

Overall a complete course to learn all 24 GOF patterns and SOLID design principles for writing better code.

2. Design Patterns by Kenny Wong on Coursera

This is an amazing online course to learn about Design Patterns on Coursera. It’s offered by the University of Alberta and delivered by Kenny Wong, one of the expert trainers on Coursera.

This course will teach you how to extend object-oriented analysis and design by incorporating design patterns to create robust, extensible applications that can withstand test of time in production.

This course is part of the Software Design and Architecture Specialization on Coursera which offers a collection of courses to teach you Software architecture and design.

You will also learn about established design patterns, how and when to use them to solve common problems which are key to designing complex software applications in Java and other object-oriented programming language like JavaScript, C++, or Python.

Finally, you will develop code sense to identify problematic software designs by referencing a catalog of code smells.

The best part of this course is the Capstone Project where you will redesign an existing Java-based Android application to implement a combination of design patterns. You will also examine a given Java codebase for code smell.

All these things make this course very interesting for Java developers who want to build their coding, design, and software skills in 2024. I highly recommend this course to both intermediate and experienced Java developers

By the way, instead of joining these courses and specialization individually, you can also join the Coursera Plus, a subscription plan from Coursera which gives you unlimited access to their most popular courses, specialization, professional certificate, and guided projects.

3. Software Design Patterns: Best Practices for Software Developers

This is an interactive coding course to learn Software design patterns on Educative. This course will teach you how to use a design pattern to write better code.

The course covers all three types of design patterns like creational patterns, structural patterns, and behavioral patterns. The best thing is that you can try out the code using those design patterns right in the browser.

If you want to master all the GOF design patterns and want to see the code where those patterns are used and how they make difference then this is the perfect course for you.

And, if you find the Educative platform and their interactive courses useful then you can also get an Educative Subscription that provides access to not just this course but their 210+ courses in just $14.9 per month. It’s very cost-effective and great for getting some hands-on learning experience.

4. Experience Design Patterns In Java

This is another great courses to learn design patterns in Java. It will teach you how to write better software by understanding common problems and applying design patterns for a better solution.

This course will teach you more than 20+ design patterns from the classic design pattern book by Gang of four, which is considered the holy bible on the subject.

For each pattern, a clear example is given to understand the problem the pattern will solve, as well as its advantages and disadvantages. You will be able to practically understand how the pattern works with the detailed included Java lessons.

After completing the course you should be able to identify common problems in your code, apply the correct design pattern, and implement a better object-oriented solution that is a lot more maintainable and readable.

5. Basics of Software Architecture & Design Patterns in Java

This course is your guide to create smart, reusable software with SOLID principles and design patterns in Java.

The course is divided into two parts, in the first part, the author talks about SOLID design principles like Single Responsibility, Open-Closed, Liskov Substitution, etc and how they help you to write better code.

In the second part, he talks about design patterns and how they solve the common problem. In order to use design patterns, you should be able to identify the problem and understand which pattern can help you and that’s where this course excels.

In short, a good course to cover the basics of software design, architecture, and design patterns in Java for writing better code.

6. Java Design Patterns — The Complete Masterclass

This one is a rather new course from Paulo Dichone, who has written a couple of best selling Java and Android courses like Java Masterclass Beginner to Expert Guide, which I have recently gone through to understand the new Java features.

In this course, he tackles the topic of GOF design patterns and he has done a really good job of explaining how each pattern works and how you can use them in your code.

His examples are from the real world and very relevant which helps to grasp the concepts. For example, using the Strategy pattern to implement a Payment processing engine is a great idea because you need to process payment in different forms like Cash, Credit Card, Coupons, Bitcoins, or maybe something else.

In short, a great course for experienced Java developers and anyone who wants to learn about GOF design patterns like Visitor, Adapter, Decorator, etc.

8. Grokking the Object-Oriented Design Interview

While this course is not directly related to design patterns, knowledge of object-oriented basics and design is key for understanding and using design patterns in your code.

The object-oriented design has always been a critical part of the software engineering interview process and many programmers struggle to answer those questions.

Even engineers, who have some sort of experience in building such systems are not comfortable with these interviews. It is mainly because of the open-ended nature of the design problems that don’t have a standard answer. This course is a complete guide to master the Object-Oriented Design.

This course is designed by the hiring managers of Google, Facebook, Microsoft, and Amazon. It not only has a set of carefully handpicked case studies, which have been repeatedly asked at the top tech companies but also provides a thorough experience to handle different object-oriented design scenarios.

If you are preparing for a coding interview or just want to master OOAD this course is a good place to start with.
