Software development has become a vital part of almost every business of any size in recent years. We had previously discussed the benefits of such innovative technologies as Artificial Intelligence and Machine Learning for the Finance, Banking, Retail, Manufacturing, and Food industries, but today we will take a different path. Instead of highlighting another type of groundbreaking technology that is already changing the game and has even more potential in the future, we will look at the programming language that had been in the arsenal of software developers for decades and is currently used by nearly 8 million engineers worldwide. We will review the benefits of the programming language itself, provide a detailed description of how software engineers code in it, and offer you some tips and information on salaries if you are interested in hiring them. You will learn the pros and cons of forming an in-house team and hiring outsource specialists. Building an efficient remote team is especially important during the Coronavirus pandemic, so you will definitely understand the basics of hiring the right experts after reading this article. Are you ready? Let’s get started!
“Truth can only be found in one place: the code.”
― Robert C. Martin
Introduction: Who is a Java Developer?
Why this language is so beloved among programmers? What should programmers coding in this language know? How programming in Java can benefit your business? We will answer all of those questions in detail in our article!
First appearing on May 23, 1995, Java is an object-oriented and class-based programming language that was created to have as few dependencies in implementation as possible. The language was built for the “Write Once, Run Anywhere” (WORA) approach, meaning that the code should run on any platform supporting Java without any recompilation. This programming language is widely implemented for web, desktop, mobile, big data, government, and enterprise applications.
This language was at the forefront of early mobile game development and has many other accomplishments. Java made a huge impact on the industry by providing the following changes:
- It influenced the wider adoption of object-oriented programming that has become common today;
- Test-driven development had become a common practice in approaches to software development. Java’s major contribution was the launch of JUnit in 2000.
Now, let’s find out what programmers coding in this language are responsible for and what levels exist to define them.
The responsibilities of a Java Developer
Java Developers are the masterminds behind IT solutions. They design and build software products from the ground up, recommending innovative solutions for improving user experience and the way entire organizations operate.
A Java Developer’s role and responsibilities might differ in organizations depending on the level of ownership, but typically they include activities related to building and improving software applications for the business. Java Developers might work on a specific programming task or be part of a full-scale software development life cycle depending on the situation. The programmers are responsible for:
- Designing, developing and maintaining Java application phases, code, and software.
- Conducting the analysis of software, testing, and debugging. That includes providing recommendations on the improvement of existing processes.
- Creating stipulations out of requirements and finding issues related and not related to production.
There are probably as many opinions on how to classify the programmers as programmers themselves, but hopefully, this description will be fair enough:
A Junior Java Developer’s role and responsibilities
Entry-level experts can’t work independently without constant guidance. A specialist at this level has little-to-no knowledge of the business domain. Junior Developers can find some basics of the programming language and the set of tools challenging. Thus, they can’t take on much responsibility. Consequently, having too many Junior Programmers without proper supervision can become a problem. Anyone at the beginner’s stage could be considered “junior”.
A Medium Java Developer’s role and responsibilities
A regular or mid-level expert must have a certain amount of coding experience. At this level, a specialist is expected to work independently and deliver results for most tasks without much outside help. If any problems occur, the medium-level programmer must know what exactly they need and whom to ask for the solution.
A Senior Java Developer’s role and responsibilities
Programmers at this level have even more experience and must be able to not only complete set tasks, but also design solutions. They may lack an overall vision of architecture, so their designs must be approved beforehand. They are able to mentor and even lead junior-level programmers.
Top 5 real-world applications: Why does your business need Java Developers?
We got clear about the history, popularity, and the roles and responsibilities of Java Developers, now let’s figure out the practical value of this programming language for businesses and organizations.
The best for building Android apps
In 2020, Java is still the most popular programming language for Android applications, making its software engineers Android developers. In 2019, Google started to rely on Kotlin as the main language for Android; however, the usage of Java still prevails.
The resume of this programming language is impressive, including software products like Hadoop, Apache, Storm, Gmail, Atlassian, and many more. The potential for creating more great products is limitless because Java is very convenient for remote development, easy to run on different platforms, and can be combined with other programming languages. It is important to acknowledge that you can combine Java with other languages like Kotlin, Scala, and Groovy. The concept of the Java Virtual Machine (JVM) allows the developer to get benefits from multiple programming languages, leveraging various tech stacks for the best results.
Point-of-Sale (POS) systems
This programming language is great for building software for Point-of-Sale (POS) terminals in the Retail industry. The software for terminals is usually running on Android, and Java is one of the top programming languages in which to code in this OS. Additionally, thanks to the Write Once, Run Anywhere (WORA) concept (that will be described later) it is easy to scale the system of terminals.
Programs in the Finance industry
Java is also made a name for itself in the Finance industry, being the leading language for building high-quality websites with reliable functionality. It is popular both from the server and client sides.
Big Data programs
If you are looking to leverage Big Data, keep in mind that Kafka, Scala, and Spark use JVM. Since it has been used for such a long time, you will have access to a plethora of debuggers, libraries, and monitoring tools that have withstood the test of time.
The advantages of software development with Java for programmers
Object-oriented programming (OOP)
With object-oriented programming (OOP), your data could become an object and a relationship between multiple objects can be created. For businesses, this approach reduces time and resources because you can easily reuse objects in different software products, the objects are accessible, and making programs is more organized. Additionally, the maintenance is quite simple along with the possibility to update legacy code. On the contrary, there is procedural programming and here is the difference:
This is a high-level language that is similar to human language and relatively easy to interpret, which makes the development process less sophisticated and complex. Java was built on the ideas of C++ but is much simpler, allowing experts to learn faster so they can reach the planned results. It is not as basic as Python, but any developer can learn fast and progress through expert levels — there are plenty of courses and learning materials available.
Automatic Memory Management (AMM)
Java has automated memory management (AMM), which takes over the allocation and deallocation of memory. The garbage collector finds and removes the objects that are useless to the program, which saves the CPU work and helps with optimization.
Java allows multi-threading; this means running multiple units of processing at the same time, which also optimizes CPU usage.
Write Once, Run Anywhere (WORA)
As mentioned earlier, this means that you could create a program on Linux, for example, and leverage cross-platforming by running it on any platform that supports Java Virtual Machine.
Features that protect against common security threats
All programs out of the box run inside a JVM (Java Virtual Machine), which is an engine that provides a runtime environment and is the first security mechanism of Java. Additionally, this programming language doesn’t have pointers — objects that store the memory address of another value that could lead to unauthorized memory access. Java also has a security manager — a policy that allows specifying access rules for each application.
A large community of developers
One of the reasons that this language is still so popular is due to the fact that new versions with additional features are getting released regularly. The developers in online communities and hundreds of Java-related courses have decades of experience. A massive amount of people are using it and plan to use it in the future. There is a large number of open-source libraries available that could be used to simplify the development process, especially saving time. It is relatively easier to build POCs for startups on Java, compared to other programming languages.
Standard for enterprises
Since the 1990s, enterprise apps have been one of the main focuses of Java programming. The number of well-tested libraries is astonishing. Those libraries are the building blocks for the fundamental functions of any organization. The relatively cheap maintenance is another reason why organizations have preferred Java for so long.
Since 2017, Java has received new stable releases twice a year; as of September 2020, the current version is SE 15. Previously Oracle Corporation released new versions of Java once every four or five years, but now they introduce new versions regularly. The growing popularity of the programming language became obvious and to stand out among competitors and bring more value, Java needed these frequent updates with modern features.
Outsourcing vs. In-House: What is best for software development?
The best choice for your business depends on your goals and priorities. In this quick overview, we would like to focus on the strongest sides of both approaches to find out what best fits your case. With a clear budget, deadline, and project scope, it will be relatively easier to make a decision, considering the following information.
An in-house team is the best choice if face-to-face meetings are really important for your project. With the team in your actual office, you can receive quick feedback, control, and coordinate your experts as much as needed. You can forget about language barriers or cultural differences — ease of communication and the ability to change direction are the main advantages here.
Outsourcing a software development team has the edge in scalability and the intellectual capabilities of the talent without any dependency on geography. Partnering with an outsourced firm can give you access to the experts that you actually need for the job. With in-house team experts, you must always have tasks for them — but in this case, you hire people for specific goals in a certain time period. An outsourced team is much cheaper because you skip the recruitment process, training, and even interviews to find the appropriate candidates. Your experts keep their jobs based on performance and not any other commitment. Market delivery is much faster because of the performance-based approach. Most importantly, the pool of available experts is basically limitless, compared to an in-house team.
If you choose to form a team in your office, all the details on hiring the right people are suitable for another set of articles. But in case outsourcing seems like the best option for your goals, we will dig deep into the details on hiring remote Java Developers next!
How much does it cost to hire Java Developers?
Last year, there were nearly 8 million Java developers in the world working with 90% of Fortune 500 companies. Switzerland has the biggest average annual salary for developers of this programming language at $93,925 including taxes, with the United States at $74,190 and Israel at $69,007. PayScale researched salaries depending on the level of expertise, and here is what the top of the list looks like:
So, a Junior Developer’s annual salary is around $63,000 on average. A Mid-Level Developer scale could expect $75,000 on average. Senior-level experts might expect around $122,000 a year.
Hiring a Java Programmer in the United States may cost you around $96,000 a year, taxes included. In Germany, the same expert may cost you around $80,000 and in the United Kingdom, it could average $60,000.
Thus, it makes sense to look for software engineers in Eastern Europe. Ukraine is one of the countries with proficient expertise in Java with over 8,000 programmers working on real projects. The interest in this technology is rising and the price for hiring experts from this country could average $30,000 a year! There are over 200,000 software engineers in general in Ukraine, and more than half of them are ready to work 40-60 hours per week. Ukraine is a great choice for hiring Java Programmers if you are interested in outsourcing your tasks and it fits your business goals.

Some tips on hiring remote Java Developers
The following tips might help you to recruit programmers.
Choose the best cooperation model for outsourced Java development.
If you have technical skills and require experts for specific goals, hiring a freelancer could be the easiest and the most effective option. However, if you have a long-term project with a scope that might change in the future, partnering with a software development company can work out better. One of the most important parts of partnering with another company is choosing the right engagement model. Learn more about models like Extended Team, Dedicated Team, and Managed Product to find out how you can benefit. In a nutshell, the right cooperation model can spare you the hassle of hiring experts and managing the development process, letting you focus on the business aspects.
Be specific in your requirements.
Make sure that the recruiting team is not using generic Java Developer job descriptions that really don’t say anything about the actual job. Your candidates must understand the specific set of technical skills as well as the soft skills required. Highlight the key technologies in your stack and the domain of your business — that might narrow the number of candidates and help you find the right people faster.
Get motivated experts.
On the other hand, it is important for you to understand the motivation of potential candidates. You must understand what exactly drives certain experts to be a part of your company. Is it a good salary or an interesting project? Or maybe it is an opportunity for potential growth? Clearly understanding the motivations of your employees may help you keep them on the team in the most challenging situations.
Our Expertise in Java Development
SPD Group has been offering Java development services to businesses since 2006. Currently, we have over 200 experts proficient in Java as well as other technologies that bring value to organizations. Over 70 of those experts are Oracle-Certified Java Developers, and this number is constantly increasing. The projects they are working on include businesses in the Finance, FinTech, E-Commerce, Biotech, Travelling, and Logistics industries.
While developing and improving a product for a leading financial data provider and SaaS, SPD Group leveraged Java development expertise for scaling both organizational and development processes. This was necessary to move the entire organization from monolith to microservice architecture. Switching to microservices allowed each team to be responsible for a particular component (or service) in the organization, eliminating the drawbacks of having a single code repository.
Java has a great infrastructure for developing microservice architecture. In this particular case, we implemented microservices into the financial data provider’s ecosystem by using frameworks such as Spring and gRPC. As a result, this financial data provider now has multiple sub-teams that are working on different business goals separately, and the team from SPD Group continues to split micro monoliths into smaller parts for better overall performance.
Among the technical highlights:
- In the microservices growth process, Java’s support and integration of Open API contracts dramatically simplified communication between them.
- Using Java allowed the implementation of a heavy-load search system with the ability to find information by hundreds of criteria among a dozen data sources with a response time of up to 100 milliseconds. This search system included the ability to sort, filter, and analyze this information.
- A mini version of the file-based key-value storage optimized for project-specific read-write operations was easily implemented using Java.
For this as well as other projects, we had teams in different countries. Thanks to using Java these collaborations were very efficient, with all key decisions made quickly and consistently.
Who is a Java Developer?
This is an expert proficient in the Java programming language who is able to design, develop, and maintain software applications. Entry-level experts can’t work without supervision, but senior-level specialists can design entire solutions for projects; that’s why the required knowledge and tech skills are different according to expertise level.
What is the difference between the most common type of developers?
You can find the following terms being used in the wrong context sometimes or lacking a precise definition. Here are some of the most popular misconceptions about this programming language and the developers working with it, so if you are still having trouble distinguishing them this will hopefully clear things up for you.
Java Developer vs. Web Developer – a Web Developer is an expert who does coding for a website or builds a web application; they can use any programming language for that purpose. A Java Developer focuses on one language and can use it for other purposes, not just web applications or websites. A Java Developer can be a Web Developer, but not every Web Developer is proficient in Java.
Java Developer vs. Android Developer – most Android applications are built using Java; however, Android developers can use Kotlin for the task. In fact, Kotlin with its rising popularity among experts and organizations holds second place to Java in Android development. So while there are reasons for these terms to be synonymous, they are definitely not the same.
Who is a Java Full-Stack Developer?
A Full-Stack Developer can work with any layer of the web development stack, including the front end, the back end, and databases. Usually, this type of developer specializes in one or more layers. A Full-stack Java Developer specializes in a full stack of tools and frameworks that work with Java. The list of required technologies includes Core Java, HTML, CSS, JS, SQL, NoSQL, ReactJS, VueJS, JSP, Spring, JUnit, Selenium, and Git.
Why should I use Java for my business?
Because this programming language is a standard for enterprises, has regular updates, is supported by a large community, and is great for remote development.
How can I effectively hire Java Programmers who can bring value to my organization?
It depends on the situation. Sometimes you can hire on-site experts, while other times it is better to look for remote specialists. Partnering with a software development company will not only give you access to software development, but also can help you avoid increased managerial responsibilities.
Despite its age, Java is currently experiencing a rise in popularity and has limitless potential for the future. In 2020, the number of Java Developers increased by 20% compared to 2019 and there are many good reasons for that. Developers are learning this technology because new versions are being released regularly with all the features necessary for modern development tasks. There are some drawbacks to this technology, but all of them can be solved.
Probably, the main advantage of Java for enterprises is that this programming language allows for efficient collaboration among remote teams; that’s why businesses should consider hiring Java Programmers for development tasks in the current situation. Nobody knows when things will return to normal after the current global pandemic, so there is a high expectation that more businesses will switch to remote work in the near future. Your business can benefit from collaborating with development teams from other countries. Consider SPD Group as a trusted software development partner that can help to bring your vision to life!
