By the end of 2021, Java was ranked the second most popular programming language on the TIOBE index, topped only by Python. The Index measures the popularity of different programming languages and is updated monthly.

Thus, the future of Java looks bright, showing us that there will still be a strong demand for Java programming professionals like full-stack Java developers for the foreseeable future. So, let’s look at the Java developer roadmap for 2022 and see how to best leverage Java knowledge into an exciting and lucrative career.

We will also give a quick Java introduction and the role of Java in cloud computing in the context of developer career options.

Java: A Brief Look

According to Java’s website, Java is “is a programming language and computing platform first released by Sun Microsystems in 1995.” Java is an object-oriented, class-based, general-purpose language widely used for coding applications and has been popular among developers for over 20 years. The compiled code of a Java application (called "bytecode") runs on most operating systems, including Windows, Mac OS, and Linux.

Java was created by Sun engineers known as the Green Team as a language for digital devices such as set-top boxes and televisions. However, the language was too complex for machines at the time, but it was an excellent fit for Internet programming. Java was first known as "Greentalk," then "Oak," and finally "Java."

There have been 19 versions of Java released thus far, with the 20th version slated for a March 2022 release.

The Java Developer Roadmap

Let's explore the roadmap for becoming a full-stack Java developer. Full-stack developers can work equally well with front-end and back-end software (also called client-side and server-side, respectively), and this versatility puts them in high demand. Full-stack developers can do it all.

Note that this Java developer roadmap is not the only one available. There are many paths up the mountain, as the saying goes. However, this particular roadmap offers a balanced, comprehensive, and realistic approach.

Front-End Development

These tools and skills are the foundations upon which you will build the rest of your Java developer roadmap. You should master these fundamental web development tools:

You then need to familiarize yourself with Integrated Development Environments (IDE):

  • Sublime Text 3
  • Visual Studio Code IDE

And, of course, since you’re focusing on front-end development, you need to know front-end frameworks like:

Finally, you should become familiar with User Interface (UI) libraries like Bootstrap CSS and Material UI.

Back-End Development

For starters, you obviously need to master Core Java, including Java 8 features, also known as Java functional programming.

Speaking of Java, back-end developers also need to learn Java build tools like:

Like the front-end technology, back-end development has its IDEs:

  • Eclipse IDE
  • Intellij IDEA
  • Spring Tool Suite

Back-end developers need to work with different databases, so they should become familiar with No SQL and relational databases like:

No SQL databases

Relational databases

  • MS-SQL Server
  • MySQL
  • Oracle
  • PostgreSQL
  • SQL Server

Cloud databases

  • CosmosDB
  • DynamoDB

Other necessary back-end technologies include:

Build DAO/Repository Layers

  • JPA/Hibernate
  • Spring Data JPA

Build REST APIs in Java

  • Jersey REST Framework
  • RestEasy Framework
  • Spring Boot

Secure REST APIs using Spring Security

  • Authentication
  • JWT
  • Role-based authorization

General Knowledge Development Skills for Your Java Developer Roadmap

  • Learn about GIT and how to create a few repositories on GitHub. Make sure to share your coding with others. GIT is a valuable tool for version control and project management.
  • Familiarize yourself with HTTP(S) protocol, request methods (DELETE, GET, OPTIONS, POST, PUT, PATCH).
  • If you haven’t become a Google search expert, learn how, especially using advanced search techniques.
  • Read up on algorithms and data structures.
  • Learn about Docker and how to deploy projects in Docker containers.
  • Learn Jenkins to help you master the concepts of Continuous Integration/Continuous Deployment (CI/CD).
  • Project management software like Jira, to help track issues and bugs.

Deployment

The cloud is the future, so master deployment with:

Testing

Familiarize yourself with a handful of Behavior, Integration, Load, and Unit testing resources like:

  • Assertj
  • CitrusFramework
  • Cucumber-jvm
  • Gatling
  • Hoverfly-java
  • Mockserver
  • Rest-assured
  • Truth

Also, consider learning Selenium to cover end-to-end testing chores.

There are other resources you can tack on to your roadmap. For example, some roadmaps get tremendously complex and inclusive, adding elements such as Logging, Caching, Object-Relational Mapping (ORMs), API Clients, and Task Scheduling. But the above roadmap is a good fit for most aspiring Java developers; you can always add on more skills later!

Java Developer Career Options

There are many Java-based developer career options to choose from. They include:

  • Junior Developer: Consider this an entry-level position. Everyone starts here. Junior developers write, test, analyze, and debug code.
  • Senior Developer: They oversee an entire project, write some code, and act as a liaison to management.
  • Java Web Developer: This position typically emphasizes back-end development, and the developer is responsible for deploying and maintaining the code on the server’s side. Since many servers are moving to the cloud these days, developers should have experience and skills in coding within a cloud environment.
  • Java Architect: Conventional architects design buildings. Java architects design and develop an application’s layout.
  • Java EE Developer: These developers build and maintain enterprise-level software and typically get hired by big companies.
  • Java Android Developer: The Android mobile operating system market share is considerably greater than iOS, so there’s a greater demand for professionals who can build or add features to Android-based apps.
