Everything you need to know about hiring Java Developers

In the following blog article, we will take a closer look at the topic of hiring a Java developer as this could be quite a difficult mission. We’ll cover topics like what are the current use cases for the Java programming language, what to specifically look out for when hiring a Java developer and give tips for the hiring process.

Simple Definition of Java

What is Java?

 

Java is an object-oriented programming language owned by Oracle Corporation. It has gained widespread popularity and is now considered a standard for developing applications that can run on multiple platforms, including Mac, Windows, Android, iOS, and more. Its “Write Once, Run Anywhere” (WORA) feature allows for cross-platform portability, making Java ideal for various devices, from mainframe data centers to smartphones. Currently, over 3 billion devices use applications developed with Java, highlighting its dominance in the programming world.

What does WORA mean?

 

write once run anywhere; it is a paradigm that allows an application to run on different platforms without having to generate different source code for it.

 

What is Java used for

 

With a wide variety of applications and use cases, Java was one of the most popular programming languages last year and continues to do so in 2023. Right off the bat, Java is all about flexibility due to the huge range of frameworks available. So, be aware of which framework skills your new Java developer should already have, or which are similar to your requirements.

 

In the next part follows what are currently the most common use cases for Java, aka:

Where you might need Java Developers

 

AI Development

Java provides a human-readable and writable codebase. Additionally, as an object-oriented language, it facilitates the development of AI algorithms. Java’s platform independence allows it to run on any platform, making it an ideal choice for AI application development. With its solid features, Java enables the construction of advanced AI algorithms capable of making informed decisions, data processing, and executing various tasks.

 

Frameworks a Java developer in the field of AI Development should know:

 

  • Apache Jena
  • PowerLoom
  • Acceleo
  • d3web

Web app Development

Java is a popular choice for developing web applications, ranging from e-commerce websites to social media platforms and enterprise-level systems. Java frameworks such as Spring, Struts, and Hibernate are widely used for building robust web applications.

 

Frameworks a Java developer in the field of Web Application Development should know:

 

  • Spring
  • JSF
  • GWT
  • Play!
  • Struts
  • Vaadin
  • Grails

Big Data Processing

Big Data involves extremely large and complex data sets that cannot be processed with traditional data processing software and tools.

 

Java’s performance and scalability make it a suitable programming language for handling substantial volumes of data. Additionally, many big data tools like Apache Hadoop, Apache Spark, and Apache Kafka are developed in Java and have Java APIs, simplifying their integration into Java-based big data pipelines for developers.

 

Frameworks a Java developer in the field of Big Data Processing should know:

 

  • Apache Hadoop
  • Apache Spark
  • Apache Storm
  • Apache Mahout
  • HPCC
  • Qubole 

Blockchain & Cryptocurrency Development

Java’s portability makes it an excellent choice for writing code that functions well across various languages, including blockchain technology. Its “write once, run anywhere” feature enables the efficient use of blockchain technology and thus the creation of cryptocurrencies.

 

Moreover, Java’s plugin architecture is one of its significant advantages in the blockchain field. With plugins for cryptographic architectures and extensions, the programming language offers a wide range of possibilities. Additionally, Java provides a well-defined interface and documentation, streamlining the development path for blockchain applications.

Tools a Java developer in the field of Blockchain & Cryptocurrency Development should know:

 

 

IoT (Internet of Things)

The Internet of Things (IoT) refers to the networking of physical devices that need to communicate and share data, although the term itself can be somewhat vague. As the need for device communication has increased, various methods have been utilized. One such example of this necessity can be seen in the communication between airplanes and traffic controllers.

 

Portability: Java was designed with device connectivity in mind, making it an ideal programming language for IoT applications.

 

A Java developer in the field of IoT should know:

 

  • Embedded applications: IoT is a combination of multiple technologies, that includes cloud computing, big data, hardware devices and so on

 

Mobile App Development

When it comes to mobile applications on android, Java is the programming language of choice. With numerous built-in features, Java optimizes resource usage and improves product performance. Moreover, Java can seamlessly handle a large number of users without compromising the speed of the product.

 

Another key point is that developers are able to execute the application code using the Java Virtual Machine (JVM). This approach not only enables cross-platform compatibility but also ensures a high degree of security – which is crucial today.

 

A Java developer in the field of Mobile App Development should have:

 

  • Experience in mobile application development, as close related to your project as possible

Game Development

Java is also a widely used programming language in the development of both desktop and mobile games. Several popular game engines, such as LibGDX and jMonkeyEngine, utilize Java as their primary programming language. So if you are planning to create the next gaming hit, be sure you get a qualified Java expert.

 

A Java developer in the field of game development should have knowledge in one of the following areas:

 

  • Computer Games Programming and or design
  • Games Technology
  • Computer Science
  • Software Engineering

Which types of Java Developers do you need?

Back-end Java Development

 

Java is mostly used for backend programming:

 

The frontend and backend of a website require different programming languages to function properly. In the frontend, developers work primarily with HTML, CSS, and JavaScript.

 

On the other hand, the backend requires server-side programming languages such as Python, PHP, Ruby, and Java.

 

Why is Java popular in backend development?

 

  • Security: Large variety of API tools, security algorithms and protocols are available 
  • Cross platform: Huge library of frameworks and the WORA principle 
  • Multi-Threading: CPU-intensive tasks are more efficiently under Java and taks do not stack because of separate threads to process for each user request

 

A back-end Java Developer should have the following:

 

Technical Skills

 

  • A very good knowledge the current frameworks like we mentioned
  • Expertise in API (Application Programming Interface) development – XML and JSON
  • The capability to use certain tools to design the architecture of a website/web application
  • Be familiar with servers because its most commonly used to deliver services
  • Have a complete skill set: Knowledge of HTML, CSS and JavaScript to complete the backend workfield (see full stack java developer)

Further Skills of Java Developers

Generally speaking a good Java developer should have an elementary understanding of the requirements of a website or mobile application in terms of performance to deliver efficient solutions for your tech project. In the previous section we went over the technical skills needed but what about the soft skills?

 

Soft Skills

 

Communication

Whenever with the team, clients or stakeholders, the ability to communicate in a clear and concise manner is essential to ensure everyone gets the message

 

Problem-solving skills

Troubleshooting issues is the bread and butter of programming, right?! Your next Java developer should know how to help himself (stack overflow, i’m looking at you)

 

Collaboration

In order to deliver high quality work it is of course important to collaborate with the team to make the dream work!

 

Attention to detail

Detecting and correcting errors, ensuring that the code is all clean and well-documented is key

 

Continuous learning

Ever evolving technologies, new frameworks and tools – your next Java developer should have the drive to learn and increase his skill set, that’s the way to stay competitive!
