From the start of this year, many of my readers have been asking me questions on what should they learn in 2021? I have written a series of posts to help them like 10 things Java programmer should learn in 2021.
In this article, I am going to share some of the most popular and useful frameworks Java Programmer can learn in 2021 to further boost your skillset and give your career a boost.
As I have said before, technology is changing rapidly and what works 10 years before may not work now and the biggest challenge for programmers is to keep themselves up-to-date.
Good knowledge of popular libraries, frameworks goes a long way in developing a new application and your day-to-day job. It's particularly important for experienced programmers or full-stack Java developers as it's expected from them that they know the latest and greatest tools for application development and can suggest the right tools for the job.
Here is my list of 10 popular frameworks which you can look forward to learning in 2021. They have changed how you develop a web application in recent time, particularly Angular and React JS and this is probably the right time to get familiar with them
I have been using the Spring framework for many years, hence, when I first introduced with Spring boot I was totally surprised by the relative lack of configuration.
Writing a Spring-based Java application using Spring Boot was as simple as writing a core Java application using the main() method.
Even though I have tried Spring Boot, I have yet to learn many things and that's why it's on my list of things to learn in 2021 for a long time.
I have also bought Spring Boot Masterclass, one of the best online course to learn Spring Boot from Udemy in just 10$ last month and I look forward to using that in 2021.
Btw, if you don't mind learning from free resources then you can also take a look at this list of free Spring Boot courses.
And, if you need more choices, you can also refer to this excellent list of Spring Boot Courses for Beginners.
This is another big data framework that is gaining popularity. Apache Spark is a fast, in-memory data processing engine with elegant and expressive development APIs to allow data workers to efficiently execute streaming, machine learning, or SQL workloads that require fast iterative access to datasets.
You can use Spark for In-Memory Computing for ETL, Machine Learning, and Data Science Workloads to Hadoop.
I have already shortlisted Apache Spark Fundamentals course from PluralSight to go through in 2021.
If you are in the same boat, you can check out that course to get some inspiration and if you need some free alternatives to just look around and get hang of it, you can check this list of free Apache Spark courses for Java, Scala, and Python developers.
It allows web developers to create large web-applications that can change over time without reloading the page. The web development world is divided between Angular and React and it's up to you what you choose.
Most of the time it's dictated by circumstances, for example, if you are working on a React based project then obviously you need to learn React.
Anyway, if you decided to learn to React in 2021 then React 16 --- The Complete Guide by Max is a good starting point. It's another gem of course from Max, probably the best Angular and React instructor on Udemy and maybe on the internet at the moment.
You can use node.js to create dynamic web pages on the server-side before you send them to the client.
Angular 2+ provides declarative templates, dependency injection, the end to end tooling, and integrated best practices to solve common development challenges on the client-side.
Since Google is behind Angular, you can also be rest-assured by performance and regular updates.
I strongly believe Angular JS or Angular 2 is here for the long run, hence, investing time in it is completely justified. If you decide to learn Angular 2 in 2021 then Angular 2: Getting Started on Pluralsight is a good starting point.
And, if you like one alternative then Max's Angular 8 --- The Complete MasterClass is another gem of the course. Max is one of the instructors I admire a lot and his courses are just awesome.
This is another popular open-source, front-end web framework for designing websites and web application. Initially brought to us by Twitter.
Bootstrap supports responsive web design which means the layout of web pages adjusts dynamically depending upon the browser's screen size.
In the world of mobile, BootStrap is leading the way with its mobile-first design philosophy, emphasizing a responsive design by default.
If you are a full-stack web developer and don't know BootStrap, 2021 is the right time to learn it. The BootStrap 4 From Scratch is a good starting point for your BootStrap journey in 2021.
And if you need some free alternatives this list of free Bootstrap courses is also very useful.
You can do animation, send HTTP requests, reload pages, and perform client-side validation by writing just a couple of lines of code.
If you decide to learn jQuery in 2021 then I suggest you take a look at jQuery master class, a free online course from Udemy for learning jQuery.
There is no substitute for security and in 2021 it would be even more important. Since Spring security has become synonymous with web security in the Java world, it makes perfect sense to update yourself with the latest release of Spring security in 2021.
The new version 5.0 of Spring security includes many bug fixes and a complete new OAuth 2.0 module.
Even if you don't know Spring Security, you should consider learning it in 2021 and there is a no better way than joining Eugen Paraschiv's Learn Spring Security MasterClass with OAuth.
Big Data and Automation is the focus of many companies in 2021 and that's why it becomes important for programmers to learn Big data technologies like Hadoop and Spark.
The Apache Hadoop is a framework that allows distributed processing of large data sets across clusters of computers using simple programming models.
It is designed to scale up from single servers to thousands of machines, each offering local computation and storage.
It's based upon the popular Map Reduce pattern and key for developing a reliable, scalable, and distributed software computing application.
I have already enrolled in The Ultimate Hands-On Hadoop last month and if you decide to learn Hadoop in 2021, you can join too.
The Spring Framework is the most important framework for Java developers, particularly for implementing the back-end of your application. The latest version of the Spring framework is Spring Framework 5.0. which brings a lot of exciting features to the Java world like the Reactive programming model and the adoption of Java 8 and 9 features.
Spring 5.0 adoption is increasing with every passing day and that's why every Java developer should learn and explore the new features introduced in Spring 5.0. If you need some help, Spring 5.0: Beginner to Guru is a good course to start with.
Another worth noting is that Vmware provides Spring certification which is not very costly and gives you an opportunity to get the recognition of your Spring Framework skills.
It's also a great way to learn Spring in-depth and fill the gaps in your existing knowledge. If you want to learn more, I have written about How to Crack Spring 5.0 Professional certifciation, you can check that article as well.
These were some of the most popular frameworks for Java full-stack developers in terms of jobs, career, and growth. There are many alternatives to each of them like for Microservices you can also look something like MicroNaut and
That's all about which frameworks Java developer should learn in 2021. These frameworks are in great demand, particularly, Spring, Node.js, and Angular JS. Learning these frameworks will not only improve your chances of getting a job but also opens many doors of opportunities.
Even if you are settled down in your job, keeping yourself up-to-date with the latest and greatest technology is essential for your career growth.
So, I suggest you pick a couple of these frameworks and learn them in 2021. If you are a Java developer then Apache Spark is a good choice, but if you are interested in a programming language rather than a framework or library then Kotlin looks good in 2021.

Thanks for reading this article so far. You might be thinking that there is so much stuff to learn, so many courses to join, but you don't need to worry.
There is a good chance that you may already know most of the stuff, and there are also a lot of useful free resources which you can use, I have also linked them here and there along with the best resources, which are certainly not free, but worth of money.
When it comes to learning, I am a particular fan of Udemy courses, not just because I'll get paid if you buy any course which is not free, but becuase they are very affordable and provide a lot of values in a very small amount, but you are free to choose the course you want.
At the end of the day, you should have enough knowledge and experience about the things mentioned here.
Good luck with your 2021 learning journey! It's certainly not going to be easy, but by following this roadmap and guide, you are one step closer to becoming the full stack Java developer, you always wanted to be
