How to become a Java Developer? Recommendations
Today many people ask themselves the question: how to start working in IT? We recommend paying attention to the study of Java. It is one of the most popular and powerful programming languages applied in various software areas.
Java language from Sun Microsystems (now owned by Oracle) appeared in 1995. For more than 25 years, it has been a popular language for developing programs and applications. This is because Java can be safely called an object-oriented general-purpose language with strict typing. When creating the language, the developers were guided by the principle of «write once, run anywhere», which means the ability to run the code once on any platforms: Windows, macOS, Linux, Android, and others. This is the responsibility of a virtual machine (JVM) in an installed Java Application Runtime Environment (JRE), which compiles Java byte code.
What does Java Developer make?
First of all, he writes a code! Not only for Android smartphones or tablets but also for devices such as smart lights for the home, industrial sensors in factories, and offline control systems in cars.
The main areas in which Java is used are:
- Websites (server part or backend)
- Smartphone applications with Android operating system
- Internet Things – Automation and Interaction of Household Appliances, Home Systems and Sensors
- Desktop Applications
- Document and office management systems
- Financial (bank, exchange) and industrial software
- Medical and Insurance Solutions
- Cloud storage system
- Tools for analyzing huge amounts of data (Big Data)
- Software testing
- Computer games and games for mobile gadgets
Because of the wide use of the Java programming language, the specialist will be able to work in that field in which he always dreamed, be in demand, and count on proportional career growth.
Automation is needed everywhere, which means that Java programmers are provided with work for at least the next 10-15 years.
Benefits of Java
Recently, Oracle and other companies have been actively developing Java. New versions are released every year, the community grows, and frameworks and libraries multiply. We can say that the Java language is getting younger – it is becoming more relevant and more popular.
Every language has its strengths and weaknesses. The advantages of Java are: first, convenient and simple syntax. Second, versatility and cross-platform. Any code created in Java can be run on any device and operating system where the runtime is already installed.
The greatest value in modern software development is time. It is necessary not only to quickly launch the solutions but also to guarantee their quick operation. Java allows you to write very productive programs for quick calculations. Ready-made frameworks and libraries help to do this in a short time.
What can you build using Java?
Over the years, Java has managed to create an entire ecosystem that consists of many libraries and frameworks time-honored and tested. By the way, the best backend for webmasters in 2022 was written in Java – Spring Framework. You can use this programming language for network development because Java supports different communication protocols. Java is also a popular content management system for websites and online stores. Knowing this language, you can quickly launch an online store or site with cool animation, expand the functionality of an existing resource or link a new table in the database with the interface. This is what is in demand and where specialists are always needed!
In addition, Minecraft is written in Java. It is one of the most famous games on the planet: it has millions of fans aged 3 to infinity. If you haven’t played, you’ve probably met a merch or seen memes from this game.

Java is a promising language, popular in a lot of interesting projects with attractive budgets.
Java developer is a good profession to start in Tech. You can develop both in the direction of project management and with a focus on business analytics. You can launch your startups in parallel with the performance of tasks in the company, or go freelance and develop websites for online stores, which is equally important and in demand.
Representatives of this specialty constantly master new technologies. If you have a good base, learning will be simple and comfortable. Case for small: to build this base.
How to learn Java from scratch?
There are several ways:
- graduate from classical university
- practice independently
- sign up for courses
But college takes a lot of time. Self-education gives no guarantees. And to become a Java programmer in two months, you have to be a developer experienced in C++ 🙂
Our recommendation is to be thorough and curious. If there is a desire and time to get a college degree – nice, it will not be superfluous. This will give you a base and a common understanding of what you have to deal with and where you will move on. Is there any point in taking a course after that? Yes, there is. As we mentioned earlier, Java is not in place, on the contrary, it is constantly being updated and improved. It always makes sense to update your knowledge. Should you focus on self-education? Of course, you should! Personal development and your development as a specialist in any sphere is necessary, at least for the sake of career development and confidence in their demand.
What should Java Developers read?
We referred the question to Egor, Java Developer of NLT. Based on his experience, he gave the following recommendations for literature:
- Head First Java (Bert Bates & Kathy Sierra)
- Core Java: Fundamentals (Cay S. Horstmann)
- Effective Java (Joshua Bloch)
- Head First Design Patterns (Eric Freeman, Elisabeth Robson, Bert Bates, Kathy Sierra)
- Head First Object-Oriented Analysis and Design (Brett McLaughlin, Gary Pollice, David West)
“It is always important to take on challenges. The Internet is full of resources for studying Java” – said Egor.
