What Is This Article About?
First, we’ll sum up what Java is and why it has a prominent place among programming languages. Then, we’ll talk about different aspects of being a Java programmer, Java programming career paths, salaries, and how you can become a Java programmer.
What Is Java?
Java has been one of the most dominant programming languages on the market for a long time. It appeared in 1995, and it is still on the top of the list of popular languages to this day.
It is an incredibly versatile technology, partly due to the fact that it runs on virtually any device that has the necessary virtual machine, the JVM. Java is therefore platform-independent, as its slogan “Write once, run everywhere” implies.
We’ll highlight some of Java’s key features, but if you want to read more about the language in detail, we recommend our article titled Beginner’s Guide to Java Programming Language. If you’re specifically interested in the background to platform independence, we recommend The JVM in action – Java and platform independence.
Java Programming Career – Features of Java
- Java is a high-level programming language:
There are programming languages that are less distant from the “logic of the computer”, formulating and writing instructions in a way that does not use human language expressions, but rather resembles mathematical-logical notions. These are low-level programming languages (importantly, this is not a qualification, just a name).
High-level languages, on the other hand, are more similar to human languages and easier to learn as a beginner programmer. Java is one such language, using English words, their abbreviations and various symbols.
Java was specifically designed to make it easy to apply the object-oriented methodology. This means that in Java, you can model the world through objects. Each object and the classes that hold them together have their own properties and methods, just like objects in real life. This approach greatly simplifies many programming tasks.
- General purpose:
It is not designed to solve a specific programming or technological problem, but is used in many different forms and frameworks across the IT sector.
It runs on any device that has the necessary environment to run it. You can write programs in Java for phones, computers, and embedded programs to operate any machine. It would be easier to list where Java cannot be used than where it can.
Java Programming Career – Where Do Java Programmers Work?
What do Java programmers typically develop and what kind of projects are they involved in?
- Backend web development – the underlying infrastructure behind websites, database management, and server-side processes. Just a few of the many examples where the backend is built in Java: LinkedIn, Amazon, Aliexpress.
- Web applications, e.g. Google services like Google Sheets, Google Slides, Gmail, etc.
- Desktop applications – pieces of software that you can download to your computer like Spotify or Slack, and development environments like IdeaJ or Eclipse.
- Mobile applications – one of the main languages of Android is Java. Some Java-based apps you might have on your phone: photo gallery, calendar, QR-code reader, Netflix, Tinder, Google Earth, Wolt, etc. You can read more about this here: Basics of Android programming – Java or Kotlin?
- Big data and artificial intelligence – teaching machines to “think” and make decisions based on data. Read more about the connection between Java and artificial intelligence in this article: Is Java the Best Language for Artificial Intelligence Projects?
- Game development: some of the most famous games are written in Java, others use C++ or C#. Games based on Java are Minecraft and FIFA, for example.
- Embedded systems – there are a lot of machines that work with embedded computers, and a significant amount of these use Java. You can see some applications for embedded systems in the picture below.
All of these machines can communicate with each other, and if they become parts of a network, we call them the IoT (Internet of Things).
Java Programming Career – Java and Business Software
Business software are powerful systems that operate in the enterprise (banking, services, security, government, etc.) sector and meet the needs of such organizations rather than the needs of individual users.
Why do large companies continue to insist on Java? Because it is reliable, robust, constantly being improved, and there are many frameworks available. There are also many long-standing systems written in Java that need to be maintained, and it would be a pointlessly large and unreasonable task to rewrite them in another language.
If you are interested in the use of Java in the corporate world, we recommend this article: What Big Companies Still Code in Java: Do Major Corporations Still Use Java?
Java has a framework for developing almost any type of software. As mentioned earlier, it might be easier to collect the programming areas where Java is not used rather than where it is.
Java Programming Career – How to Become a Java Programmer?
You can approach a career in programming from different angles, depending on what kind of learning is right for you and what your goals are. We have written about learning programming and the different IT courses available in several articles. If you’re interested in the pros and cons of education systems and different types of learning, check out our previous articles:
- Top 10 Java courses for beginners
- How to choose your IT training in 2021 – the latest forms of education and locations
University Degree in Computer Science
You can study programming in a university setting, and major in software design, computer engineering, business informatics, etc. If you apply for such a program, you will get a strong theoretical and mathematical background and a good overview of the whole process of program design.
However, you will do fewer practical programming tasks, and you will probably not acquire the actual programming routine at university, but through individual projects, other forms of learning and internships.
Many programming jobs require a university degree, but not all. As we have mentioned, Java is very often used in large corporate environments, where many developer positions require a BSc or MSc in computer science.
Java Programming Bootcamp, Java Programming Course
In order to start a Java programming career, you can learn programming not only at university from professional instructors, but also in various courses. Some are part of the public adult education system, others are intensive bootcamps of 4-12 months. Bootcamps are less about theory and math, and more about programming practice, simulated work tasks and skills development.
Graduates of this type of training will find different jobs than graduate programmers, but the recruitment rate for bootcamp students is extremely high and the salaries are not necessarily lower than for a graduate IT specialist.
Two of our previous articles also cover bootcamps, check them out:
Learning Java Independently With Online Learning Materials
Learning to program is not something you can only do in the classroom. You can also make excellent progress with online learning materials that you can access from anywhere and work through on your own schedule. If it’s important to you that the course material is in Hungarian, we recommend CodeBerry’s Java course: Java programming course.

- Good analytical and problem-solving skills
- Ability to think logically and master algorithmic, inductive reasoning
Java Programmer Salary – Java Programming Career in Numbers
How Much Can You Make as a Programmer in 2021?: In this article, we analyze programmer salaries based on many sources, and we list the average wages of the top 14 professions.
The salary for a Java programmer at junior level is around HUF 600,000 before tax, while at senior level it is between HUF 900,000 and HUF 1.4 million.
Is It a Good Idea to Choose Java as a Beginner Programmer?
Yes, it is!
The basics of programming can be learned in almost any language, and if a course is designed specifically for beginners, taking into account their needs and explaining everything from the basics, it is a good introduction to the world of programming.
Although Java is not the easiest programming language to learn, we encourage you to start learning it as a beginner if you are interested in this direction and would like to work on projects based on Java.
Choosing Java as your first programming language is a good decision because it is a highly sought-after skill, and once you have reached the right level, it is a secure career option. It can take you in different directions depending on what you want to do. It provides a good basis for learning other programming languages and other technologies.
