Hello guys, if you want to learn Java in 2021, online and by yourself, and looking for the best free Java courses then you have come to the right place. Earlier, I have shared the best Java online courses and in this article, I am going to share my favorite free online courses to learn Java in 2021 from Udemy, Coursera, Codecademy, and Educative.

The Internet is full of useful resources. No matter what you want to learn there is something useful available for free. You just need to commit your time and effort. At the same time, it’s difficult to choose in the huge sea of free books, websites, and courses on the internet.

If you are not careful, you will spend most of your time browsing and changing courses without learning anything. That’s where a curated list helps. Curation is my hobby and passion. I love to read books and courses which allows me to curate useful resources and share them with you guys.

Today I’ll share 10 Java Programming Courses which beginners can use to learn Java for free.

Even though the focus is on beginner-level Java courses — because beginners are the ones who need the most guidance and help — I have tried to also include free courses which can be really useful for intermediate and experienced Java developers like this free Java Multithreading course from Udemy which is really great for both beginner and intermediate Java developers.

These are some of the really important skills, tools, and technology for experienced Java developers. If you are not familiar with them, it’s probably the right time to pick them up to boost your career and skills.

Btw, if you could spend few bucks on learning a useful and in-demand skill like Java Programming language and looking for a comprehensive resource then I highly recommend you to check out The Complete Java Programming Masterclass course on Udemy.

This 80-hour long course is the most comprehensive and up-to-date course to learn Java online, it’s not free but you can get it for just $10 on Udemy sales which happens every now and then, as good as a cup of Starbucks coffee.

10 Free Java Programming Courses for Beginners to Learn in 2021

Without wasting any more of your time, here is my list of best online courses to learn Java for FREE. I have tried to include different kinds of courses like the free courses to learn core Java as well multithreading, object-oriented programming, etc.

I have also tried to include both hands-on and theory-based courses, as well as both video, text, and interactive courses so that you can practice online without downloading and setting up Java, which is really really great for beginners who love to start as soon as possible without any hindrance.

1. Java Tutorial for Complete Beginners [Best Free Course]

This is probably the most popular free Java course on Udemy, one of the best and my favorite online learning platform. Many people don’t know that Udemy also has free courses, which are legally free. I mean made free by their instructor and creator for education and marketing purposes.

This course probably has the first-mover advantage as more than 1.2 million people have joined this course to learn Java which is a record, but at the same time, the quality of the course is quite good.

If you are a beginner at programming or know a programming language but also want to learn Java, then you can enroll in this course. It’s FREE and I guess it always remains free on Udemy and you should join this to learn Java2021.

2. Object-Oriented Programming in Java [Coursera Free Course]

This is an intermediate free Java course from Coursera, another learning online learning portal that brings the best courses from the world's top universities and organizations like Google and IBM.

If you have some experience in software development or a background in computer science, then you can take this free course to learn object-oriented programming.

This is actually a Coursera specialization which is nothing but a combination of courses and projects and offers certificates after successfully completing the course, assessments, and projects.

This specialization is offered by Duke University and more than 66K learners have joined this program to learn Java. It has four Java courses to learn Object-Oriented Programming and Data Structure in Java which you can audit for free but you need to pay if you want a certificate.

After completing this specialization, you should be able to develop an object-oriented application in Java, leverage the power of existing libraries, how to build graphical user interfaces, and how to use some core algorithms for searching and sorting data.

And, the best part is that it is project-based, so you’ll get some much-needed hands-on practice and coding.

By then way, if you find Coursera courses useful, which they are because they are created by reputed companies and universities around the world, I suggest you 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. Java Multithreading [Free Udemy Course]

Multithreading is an essential part of Java programming and probably the single most important feature which separates a good Java developer from an average Java developer.

There is a high demand for Java developers who can write robust and concurrent code. They also get paid very high salaries.

If you truly want to excel in the Java world, multi-threading and concurrency is the one area you need to conquer, then this course will help you to do that at free of the cost.

Btw, if you have a budget to spend some money on something worth learning, then Applying Concurrency and Multi-threading to Common Java Patterns By José Paumard on Pluralsight is also very good, but, of course, it’s not FREE.

You’ll need a Pluralsight membership to access the course, which costs around $29 per month/$299 per year but also gives access to their 7000+ online course library.

4. Practice Java by Building Projects [Free Udemy Course]

There is no better way to learn a new programming language than building projects. This is what I call active learning. You cannot learn by simply reading books or watching online courses until you start writing code and creating projects. This makes your mind work actively.

You get familiar with real-world requirements and then you find answers based upon whatever you have learned. In short, use this course for more involved and project-based learning.

A highly recommended free course for anyone learning Java in 2021 for both beginners and intermediate Java programmers.

Btw, if you feel that theory is bit light on this course then you can also combine this with The Complete Java Masterclass, one of the best and most up-to-date course to learn Java, but not free.

5. Java Database Connection: JDBC and MySQL [FREE]

JDBC is an integral part of Java API because most of the real world application you will create in Java will have to work with a database.

Good knowledge of JDBC is required even if you are using advanced frameworks like Hibernate, JPA, or IBatis and this course will provide you with that. It uses MySQL as an example database as it’s also free and teaches you how to work with a database in Java using JDBC.

10. Hands-On Docker for Java Developers [FREE Course]

Docker is becoming an increasingly important tools in the world of cloud-based applications. It allows you to deploy your Java Microservice easily on Cloud and it also makes it easy to scale your application and deploy multiple instances with few clicks using Kubernetes.

Docker also made the development easier as you don’t need to download individual Java tools like JDK, native libraries, JAR files, etc instead you can just run your application as a Docker container and it works. It seriously makes both the development and deployment of Java applications easier.

If you are interested in cloud-based Java development and leveraging containers for setting up new instances quickly, then this is the perfect course for you to start with.
