Top 10 Frameworks Java Programmers can Learn in 2021 – Best of many. Hey there, if you’re a Java developer looking for recommendations on which web development frameworks to learn in 2021, you’ve come to the right location. In this post, I’ll discuss the top 10 frameworks that Java developers should learn in order to keep up with modern progress. Backend frameworks like Spring and Spring Boot, as well as front-end frameworks like Angular 2+ and React JS, are included in this post.

You might ask that a Java developer will need to learn the Angular or JavaScript frameworks, but the fact is that you would need them in the real world. For instance, suppose you work on a project where the backend is written in Java but the frontend is written in Angular or React JS.

Being on a software development team requires you to apply to both the backend and the frontend, which is where this experience comes in handy. You may have already seen job postings for developers who are skilled in Java + Angular or Java + React.

In any case, this is the second instalment of my post about what Java programmers should know this year. I concentrated on critical enhancements like Java 8, Java 13, Spring 5.1, Spring Boot 2.1, and others in the first part of this post. 11 Things Java developer should know. But in this article, I’ll discuss some of the better Java frameworks you can master to advance your career.

Top 10 Frameworks Java Programmers can Learn in 2021 – Best out of Best

Technology evolves quickly; after just a few years, what was the hottest technology or platform in 2021 is no longer in operation, and keeping up with the technology is our greatest challenge as programmers and application developers.

The Spring system is a great example of this. To get a job in the Java web development environment, it used to be enough to know how to use the Spring platform. To be a part of modern-day Java development, you should know Spring Boot and Spring Cloud, Eclipse Microprofile, Micronaut, and Quarkus.

Except for Android applications, the Spring framework is the most common Java framework, and it is used in almost all Java development. It is always changing for the good of the creator, but you must still put in effort to keep up with it.

Aside from the Spring framework’s evolution, other updates in how you create a Java web application are on the way. Frameworks such as JSP, GWT, and JSF are no longer used; now, Angular and React are favoured over these standard Java view technologies, which is why all Java developers can learn these JavaScript front-end libraries and frameworks.

10 Best Frameworks Java Programmers can Learn in 2021

Here’s a rundown on some of the strongest Java implementations for the year 2021. Spring Boot is a Java web development platform; Spring Cloud is a Java Cloud development framework; Angular and React are JavaScript front-end development frameworks; and Apache Spark is a Big Data framework.

It is not important to master any of these frameworks; instead, based on your needs and job profile, you can choose the one that is most well-known. I recommend Spring Boot to most Java developers since it is now the normal way to use Spring in many businesses.

However, if you’re working on a project that needs React or Angular, go ahead and learn them.

1. Spring Boot

You may have learned about Spring Boot’s mystical abilities. It’s a game-changing application, and it’s the biggest thing that’s happened to Java since the Spring framework.

Spring Boot, like Spring, attempts to address problems associated with enterprise Java development by making it much easier for Java developers to build Java web applications using Spring.

While Spring provides a lot in terms of dependency injection and many templates such as JdbcTemplate and RestTemplate, it also requires a lot from you in terms of learning, setup, and dependency management, which causes implementation friction.

Spring Boot attempts to address this by including a number of useful features such as auto-configuration, starter dependence, Spring Boot CLI, and Spring Actuator.

This are just a few of the Spring Boot features we’ve looked at. If you’re interested in learning more about Spring Boot, I recommend enrolling in a Spring Boot course like Learn Spring Boot – Rapid Spring Application Growth.

Spring Boot in Action by Craig Walls is also a good place to start if you like reading books.

To elaborate on the auto-configuration functionality, it alleviates the pain associated with normal configuration functionalities, such as automatically configuring JdbcTemplate and an in-memory database if their JAR dependencies are present in the classpath. It makes over 200 decisions that can aid in the auto-configuration of spring network, stability, and other features.

Similarly, starter dependency saves you the trouble of writing down all of your dependencies and then trying to find a compatible edition that works best for them.

You can now get most popular dependencies by adding only one starter POM, such as spring-boot-starter-web, which can pull Spring MVC, Jackson, and the Embedded Tomcat api.

2. Spring Cloud

Spring Cloud seeks to address the problems that come with developing apps for the cloud. It gives Java developers the resources they need to easily design cloud-based application patterns such as configuration management, server discovery, circuit breaks, client-side load balancing, intelligent routeing, clustered sessions, and so on.

You don’t have to think about hardware, operating systems, databases, or other applications when developing a cloud-based Java programme. However, the app would not function without them.

Cloud vendors such as Cloud-Found and Heroku provide those services, but you’ll need to put in a lot of effort to use them, which is where Spring Cloud comes in.

It offers an easy and powerful cloud connector to access those services by abstracting all domain-specific information, allowing you to access those important services in the cloud in the same way you would in a non-cloud setting, such as connecting to a network with only the host and port and login credentials.

If you’re interested in learning more about cloud-based Java apps, such as Microservices, and how Spring Cloud will support you, I recommend Master Microservices with Spring Boot and Spring Cloud, one of the best courses for learning these two frameworks.

If you like to learn more, suggest you use the book, “Cloud Native Java” written by Josh Long and colleagues is a good place to start.

3. Angular

This is one of the most widely used JavaScript frameworks for front-end development. It was created and is supported by Google, one of the most creative organisations of our day.

Angular is a well-known architecture that has been used for a few years. Angular JS was the previous version of the project, but with Angular 2, the framework was completely rewritten.

It provides declarative templates with Data linking, as well as dependency injection and unit testing to validate the client-side code, making it a common front-end platform.

It also allows use of TypeScript, a Microsoft-developed JavaScript wrapper that makes writing Object-oriented code in JavaScript easy. It’s a JavaScript superset with a good Java-like syntax for creating modern GUI applications.

The compiler then converts the code to JavaScript, allowing it to be executed in the browser. To become a full-stack developer, I highly advise learning either Angular or React to Java developers. If you’re interested in learning all about Angular, Angular – The Complete Guide is a great place to start.

If you want to start with some free tools, this list of free Angular Courses for Web Developers is a good place to start.

4. React

React, like Angular, is a common JavaScript library for creating front-end or GUI applications. Its component-based architecture has wowed web developers all over the world.

Instead of using FreeMarker, JSP, Thymeleaf, or other typical Java View technologies, several Java projects that have a web GUI are now using React.

The biggest advantage of React is that you can generate a component and recreate it, making creation simpler. For example, if you have a list of items with only different details, you can reuse your custom list component generated with React with different data.

React, like Angular, is funded by Facebook, which means it won’t go away in a couple of years, and any effort you make in knowing it will serve you well in your career.

In summary, React is a wonderful platform to learn in 2021 for both Java and web developers, and the best course to begin with is React 16 – The Complete Guide.

5. Apache Spark

In the Big Data room, Apache Spark is the next big platform. Despite the fact that Hadoop is now more available and widely used in the Big Data space, things are rapidly changing due to Apache Spark’s improved speed and efficiency.

It’s said to be 100 times faster than Hadoop, making it perfect for processing the massive volumes of data generated by today’s global applications.

If you’re a Java developer with an interest in Big Data, learning Apache Spark will help you advance your career. There are a lot of possibilities in the Big Data room, as well as a lot of demand for a developer who has worked with Hadoop and Apache Spark.

I recommend checking out the Apache Spark with Java course on Udemy if you want to master Apache Spark in 2021. I paid $10.99 for it earlier this year, and you can do the same on Udemy’s daily flash sales.

6. Eclipse MicroProfile

Another great framework for Java programmers to learn in 2021 is this one. The Eclipse MicroProfile is a project of the Eclipse Foundations that aims to make Java EE more suitable for microservice production. The aim of this modern Java architecture is to identify a basic set of APIs for building Microservice applications and to provide a lightweight application that can run on several MicroService runtimes.

For nearly two decades, Enterprises Java technologies such as Java EE and Jakarta EE have advanced alongside the industry to support distributed application architectures built on RMI/IIOP, Web Services, and REST. The MicroProfile represents the next step in that process.

Eclipse MicroProfile 3.2 is the most recent iteration of Eclipse MicroProfile. MicroProfile 3.2, as its predecessors, remains aligned with Java EE 8 as the foundational programming paradigm for the implementation of Java Microservices.

7. Micronaut

Micronaut is leading the serverless application on the Java side, as the market moves towards serverless computing. To close this divide, Micronaut is leading the serverless application on the Java side. Micronaut is a modern, JVM-based, full-stack architecture for developing scalable, easily testable microservice and serverless applications, in case you didn’t know.

One of the best features of Micronaut is that it is a Polyglot architecture, which means it can be used to build applications in a variety of programming languages. Micronaut currently supports Java, Kotlin, and Groovy as programming languages.

Micronaut not only gives you a lot of flexibility in terms of growth, but it also performs well. Microanut offers lightning high throughput and a massive reduction in initialisation time thanks to its small memory footprint.

You can also improve the speed of your Java application by using GraalVM, which allows Micronaut apps to start in just a few milliseconds!

This is accomplished by avoiding IoC frameworks that load and cache reflection data for each and every sector, function, and function Object() { [native code] } in your code. Micronaut, on the other hand, would not limit the initialisation time or memory usage of your programme based on the scale of your codebase.

In 2021, you can learn the Micronaut architecture if you want to build a serverless application with easily testable Microservices in Java.

8. Quarkus

Quarkus is another modern Java architecture that develops Java applications using a container-first paradigm. It optimises the application for GraalVM and HotSpot, resulting in a lightning-fast boot time, extremely low RSS memory (not just heap size! ), and near-instant scale-up and memory consumption in container orchestration systems including Kubernetes.

This is accomplished by the use of a method known as compile-time boot. It also enables you to write both imperative and non-blocking reactive code without sacrificing performance while designing applications.

It’s also made with the developer’s competitiveness in mind. It offers a seamless environment for integrated developer fun, with single setup, zero-config, live to reload in the blink of an eye, simplified code for the 80 percent popular usages, versatile code for the 20 percent, and no-hassle native executable generation.

It means you can simply save the code and it will work, which is possible in Java thanks to Quarkus.

Quarkus also offers best-of-breed libraries and specifications, all of which are connected by a standard backbone. If you want to improve your Java skills, studying Quarkus could be a smart choice.

9. Hibernate

Hibernate is without a doubt the most common Java persistent system, and if you don’t know it yet, you should in 2021. Secondly, Hibernate is used in almost every Java project, particularly server-side Java applications. It also implements JPA, or Java Persistence API, which is a Java standard for persistence.

Along with the Spring framework, Hibernate is the most in-demand ability among Java developers, and Hibernate is included in nearly all job listings for the Java Web Developer role. It’s also one of the most well-known systems, but any effort you put into studying Hibernate will pay off in the long run.

If you’ve already planned to learn Hibernate in 2021 and are looking for tools such as classes, check out this list of top 5 Hibernate and JPA courses, where I’ve shared some of the best courses for Java developers to learn Hibernate and JPA.

If you prefer books to classes, this collection of best books to learn Hibernate for Java developers is a good place to start. If you ask me, I’d rather merge both courses and books in order to practise Hibernate easily and thoroughly. Courses are good for getting a good description of 20% of features that are used 80% of the time, while books are good for getting a deep dive into a specific subject.

10. Spring Core Framework

You may already be familiar with the Spring framework, but if you aren’t, this should be the first Java framework you study in 2021. Spring Framework requires no introduction because it has become the mainstream Java stack for creating server-side applications, and any Java developer is supposed to be familiar with it.

If you want to work as a server-side Java developer, you’ll need to show that you know how to use the Spring system in nearly every Java interview. Spring, like Hibernate, is a must-have ability for Java programmers.

Though Spring is a large and complex architecture with several projects such as Spring Boot, Spring Cloud, Spring Data, and others, you should be familiar with the Spring core and Spring MVC.

If you’ve already decided to learn the Spring framework in 2021 and are searching for a good place to start, I suggest the Spring Framework 5: Beginner to Guru course, which is one of the best tools for learning the framework in depth.

If you like reading manually from books, this list of simple and advanced spring books is a good place to start, and if you need more, this article has a lot of good spring tools.

Summary of the Top 10 Frameworks for Java Programmers in 2021

That concludes our discussion of some of the best Java Frameworks to learn in 2021 to advance your career. It’s important to keep up with technology because it evolves at a rapid rate, and if you don’t keep up with it, you’ll fall behind with your business and career. Technology also opens up new possibilities, such as learning Angular or React to get into Javascript front-end production or learning Spark to get into the Big Data room.

Obviously, you may be wondering why Java programmers can study the JavaScript platform. However, in most companies, a Java developer is responsible not only for server-side coding but also for client-side coding, which includes making front-end GUIs.

Even if Java is their primary ability, they must master all relevant technologies in order to be useful and valuable. That’s why most Java developers have a strong understanding of front-end technology like HTML, CSS, and JavaScript, as well as other popular skills like SQL, Linux, and Algorithms

Aside from the advancement of how we build web applications, new possibilities in the Big Data and Machine Learning field are arising, and there are unique Java frameworks such as Apache Spark and Hadoop that you should learn to take advantage of these upcoming opportunities.

The Conclusion

These days, the React is still everywhere. You must have this platform under your belt if you want to maximise your value as a Java web developer! React is well supported and still evolving, thanks to Facebook’s massive power and an increasing community of UI developers. Facebook, Netflix, the New York Times, Uber, and a slew of other tech companies use React extensively.

By the way, If you think these top 5 frameworks aren’t enough, or if you already know them and want to learn some new ones in 2021, here are some fascinating articles to read about Java frameworks for automation, research, web services, and microservices.
