“3 billion devices run Java” is a phrase proudly placed on Oracle’s JRE software installer that any present-day PC user has seen at least once. This short sentence states the universality, convenience, security, and high market demand for Java-based technologies.
Indeed, the solutions provided by the Java software development environment have proven to be an effective and reliable tool for creating applications of any level of complexity. And despite their age, not only they haven’t lost their relevance, but an organized and proactive professional community is actively developing them.
This article will take a detailed look at what software products Java programming is used today and how. You will also learn what knowledge a Java developer should have and how to hire a perfect specialist quickly and for a good price.
Why consider Java developers to hire
What has caused Java-based technologies to spread so widely and almost everywhere?
First, Java is a specific language that uses virtual machine technology to execute its code. Despite the larger amount of memory needed for computing, this solution has one significant advantage: the code written in Java is cross-platform. In other words, a Java program is written only once and is correctly executed on all devices for which suitable Java virtual machines exist. It significantly reduces the time and costs of software development and adaptation for different platforms (desktop, web, and mobile).
Furthermore, Java is a general-purpose language that finds application in almost all spheres of the modern IT industry. Java is used to develop the back-end of:
- web sites and web apps;
- desktop applications;
- mobile apps;
- console software;
- software for microcontrollers and “smart” devices;
- cloud services (Iaas, PaaS, SaaS);
- various data management systems (CMS, CRM, WRP, PIM, ERP, etc.);
- video games;
- artificial intelligence and machine learning systems.
It is not surprising that the Java programming language steadily holds its position at the top of the most popular languages among programmers and the most demanded skills on the market.
At the moment, there are several main platforms for Java software development, covering a definite range of technical requirements for projects of different levels of complexity:
- Java Enterprise Edition (Java EE) for engineering comprehensive and scalable enterprise-level software;
- Java Standard Edition (Java SE) with compilers, Java Runtime Environment, and APIs for creating custom, mostly desktop applications;
- Java Micro Edition (Java ME) for devices with limited processing power, such as cell phones, PDAs, and embedded systems;
- Java Card – for applications running on smart cards and other devices with minimal processing power;
- JavaFX – to develop desktop and web applications with a rich graphical interface.
With this variety of engineering development environments, Java applications are being designed for almost every industry: management, industrial software, finance, analytics, commerce, logistics, medical, services, and entertainment. Giants such as Google, Microsoft, Meta, and Netflix actively use Java development to run their cloud services and popular web applications with many users, such as Youtube, Whatsapp, Facebook, Instagram, and Netflix streaming service.
If you need a reliable, cross-platform, scalable application with a high level of protection, you should include Java in your tech stack and recruit competent developers.
Skills for Java developers
Like other back-end programmers, whose specifics of employment we’ve covered in the article “How to hire a software developer in 2023” earlier, the Java developer:
- writes code, creating the internal software architecture, and synchronizing it with the database;
- tests the code, eliminating bugs;
- integrates APIs, etc.
Experienced senior Java programmers make responsible technical decisions regarding development details and manage the development process.
The particulars of the Java development environment require the coder to have a confident command of specialized technical tools, which must also be known and understood by the customer to hire the right person. Below we will look at the basic hard and soft skills Java developers need to perform their duties effectively.
Variety of Java developer skills
Essential hard skills for Java programmers
What professional knowledge and development tools should a good Java coder have mastered?
Mastery of the standard Java SE development platform (Java Core)
This skill involves:
- the ability to apply object-oriented programming concepts (OOPs), linking data and functions to create clean, stable, and secure code;
- the ability to create and effectively use design patterns;
- practical use of serialization concepts to enable cross-platform code portability.
Working with the enterprise Java EE platform
Skill in creating server-side applications for complex software using JavaServer Pages, Servlet APIs, and JavaBeans components.
Knowledge of Java Build Tools
This skill entails familiarity with automated tools for building projects from source code. Knowledge of Maven or Gradle systems is often required depending on the tasks faced by developers.
Working with Frameworks
To effectively develop various applications and solve some technical issues, a Java programmer should be able to use specialized frameworks. The most famous and popular of them are:
- universal framework Spring, which is designed to create a variety of applications on the enterprise platform and includes modules Spring Core, Spring MVC, Spring ORM, Spring Security, etc.;
- Struts2 framework for developing enterprise solutions;
- Blade framework for full-stack web development in Java;
- Play framework for building high-performance web applications;
- Vaadin framework for developing Rich Internet applications (RIA);
- JSF framework for creating component-oriented user interfaces of web apps.
Operating with Java Application Containers
Ability to run and configure Java application servers such as Jetty, WebLogic, WebSphere or WildFly.
Proficiency in ORM technology
Skills in operating relational and non-relational databases, including mastering with Java Persistence API, OpenJPA or Hibernates.
Knowledge of Java testing tools
Testing program code with tools like TestNG, JUnit and Selenium and fixing bugs afterwards.
Of course, more specific tasks like cloud services integration, big data science or neural network training require expertise in additional areas.
Crucial soft skills for Java developer
When hiring a Java developer, you must be sure that he is a good team player, attentive to the needs of the client and the opinions of other team members. Of course, he should have high communication skills and a good command of English, so mutual understanding does not suffer.
The ability to self-organize and work discipline is also essential. Then you can be sure that the developer’s carelessness will not disrupt the deadline.

How to hire a Java developer: 5 tips
Recruiting professional Java developers to create a project of any level of complexity is a challenging and responsible task. Firstly, it requires technical expertise in Java development. Secondly, it is time-consuming because talented developers do not sit idle: you have to find them and get them interested in participating in your project. Otherwise, you greatly risk getting a weak specialist with high fee expectations, and wasting time, money, and nerves. To avoid this, you should have a strategy to determine how to find java developers that are needed specifically in your case.
1. Specify the technical requirements of your technology stack
As you may have seen above, Java programmers’ skills are quite different. Therefore, it is right to start your search for the appropriate specialists by analyzing your project’s goals and correctly selecting the technology stack that is capable of solving them. Understanding that the optimal tech stack predetermines fast and quality development is crucial and saves time and costly material resources.
