What makes Java one of the most popular technologies in software development?

Great for Internet of Things

Java was initially developed in the mid 1990s with an aim to allow creating apps that can be run on any device, including household items. And although the Internet of Things hasn't happened to be a big thing until quite recently, Java is still one of the best ways to build intelligent devices.

Commonly used for Android mobile app development

Java is one of the two main programming languages (alongside Kotlin) used in Android mobile development. This means that if you want to establish business presence on the 2.5 billion active Android devices, you should leave this to experts and hire Java developers.

Perfect for back-end

Back-end means all the things done on the server side of your app, such as exchanging data between users or keeping your software running on without any interruptions. Java is one of the top technologies for this, so if you are planning to launch a web app or mobile app product, you might want to hire Java developers.

Cross-platform development-ready

Java, being a platform-independent language, is widely used when developing software for multiple platforms at once. If you want, for example, to launch an app available not only on Windows, but also on Mac and Linux, this should be your technology of choice.

How To Hire Java Developers Perfectly Fitted To Your Needs?

Being launched in 1995, Java is a truly mature technology. Unlike many others, however, Java is far from being outdated and is still one of the most popular programming languages to be used worldwide.

With so many Java app development experts on the market, the question arises: how to hire Java developer that will really match my needs, my company, and the project we are currently working on?

To answer this, we decided to prepare our own guide on hiring Java devs. Read along to learn the best tips shared with us by industry insiders!

When should you hire Java developers?

Before you start looking to hire a Java developer, you’ll probably think first why you actually might need one. Java is one of the most popular programming languages worldwide, but it is especially recommended for a few specific types of projects.

So when should you actually hire a Java developer?

  1. When building a web app

    Web development can be split into two main areas: front-end (what the user sees) and back-end (processes not directly visible to users, e.g. data transfers, server management). Java is often chosen as the go-to programming language for the latter one, so if you have a web app planned, consider hiring a Java developer.

  2. When building an Android mobile app

    Java is the main language used for creating Android software. If you want to develop an app for this system that performs well, you should definitely hire Java developer with experience in mobile projects

  3. When planning to launch a cross-platform product

    Software built with Java can be run on multiple platforms besides Windows, such as Mac and Linux. If you want to establish a presence on these systems, a good Java developer is exactly what you might need

  4. When working on software for enterprises

    Java is often being used when building huge, complicated software for corporate use. Due to Java’s great performance, even when running processor-intensive operations, it’s the first choice for enterprises who require stable and safe technology to be used by thousands (if not millions) of users, e.g. online banking systems.

The ultimate Java developer job description — what your new dev should know?

Because Java can be used in so many different types of projects, the Java developer job description you prepare for your hiring process may be ultimately slightly different from what other companies have. There are some general technical skills that every good Java developer should possess, though. These are:

  1. Knowledge of popular Java frameworks (e.g. Spring and Struts for web development, Dropwizard for microservices, Hibernate for databases, Play for web and mobile apps)
  2. Experience with Memory Management in Java Virtual Machine (garbage collection)
  3. Understanding of major Object-Oriented Programming patterns and concepts
  4. Understanding of abstract methods and classes in Java
  5. Understanding of Java keywords
  6. Experience with database management (with SQL)
  7. Writing clean code


There are also, of course, skills needed for specific types of projects. For example, if you want to hire Java developers to develop a web app, they should be experienced also in the more typical front-end languages (HTML, CSS, JavaScript) as well as XML/JSON. For Java app development, knowledge of the Android Software Development Kit is crucial.

What criteria should you take into account when you want to hire a Java developer?

Besides technical skills, there are, of course, other features that you should consider when you plan to hire a Java developer. Here are some of the major ones:

  1. Their previous experience with Java

    Despite being a very popular programming language, Java is not easy to learn. That’s why, when you want to hire a Java developer, assessing their previous experience working with the technology is crucial. You should remember about checking how long they have worked in Java-related positions and whether they had any breaks. Java development changes rapidly, so someone who worked on a Java app a few years ago might not possess knowledge that’s recent enough to allow him to develop great products in a fast-paced company.

  2. Product fit

    There are so many different projects to use Java for, that extensive experience in the programming language itself won’t do if the developer is not familiar with the type of product itself.
    The rules here are, therefore, simple.
    When planning to build an Android app, hire Java developer with previous experience in mobile projects.
    When planning to build a web app, hire Java developer experienced in web development.
    And so on.
    In other words, try not to hire Java developers inexperienced in your type of product.

  3. Industry fit

    If possible, you should look for Java devs with previous experience in your industry. This will give you the advantage of having on board someone who has already built solutions that you might require for your software, which significantly speeds up the whole development process.

  4. Soft skills

    While without the needed technical skills a Java developer simply cannot code, a set of soft skills is crucial as well. A good Java dev must be able to work well with others, both devs and non-devs. This often means being able to translate very technical issues into language easily understandable by people from non-technical teams. Having an attitude of a researcher is also important — even most experienced programmers sometimes have to go online to look for inspiration on how to solve a specific problem. Finally, expert time management (to be able to cope with multiple priorities and issues happening on a day-to-day basis) is something that a good Java developer should strive to achieve.

Java developer interview questions — what are the best ones to ask?

The technical interview is always a crucial part of a successful hiring process. If framed and prepared well, it can provide you with the perfect assessment of your candidate’s skills.

The interview part focused on the technical parts of one’s job usually consists of a set of questions and a task or two to be either accomplished during the interview or at home. If you are not a Java developer yourself, you should consider asking someone to help you out with the process. Think of some colleague of yours or book some time with an expert for hire. This can be either an actual Java dev or an IT Project Manager with previous experience in Java.

To give you some idea of what you can expect, here are some of our favorite Java developer interview questions that you can use during your hiring process.

  1. What’s the Set interface in Java? What are the differences between HashSet, TreeSet, and LinkedHashSet?
  2. What is the most recent Java release? What new features does it introduce or what does it change in comparison to the previous release?
  3. StringBuilder vs StringBuffer — what are the differences between the two?
  4. Is it possible to override static methods in Java? Is it the same in other programming languages?
  5. What is the difference between notify and notifyAll in Java?
  6. What is the difference between static and dynamic binding in Java?
  7. What things in Java do you find annoying and you think they’ve been done better in other programming languages?
  8. What is the difference between a user thread and a daemon thread in Java?
  9. Are Swing methods thread-safe? Explain why or why not.
  10. What is the difference between sleep() and wait() methods in Java?

Gathering IT experts for product’s success

Building complicated Java software is always powered by teamwork, not only between developers but also experts of other professions. You need designers (including UX and UI designers) to make your product attractive to the customers; data analytics experts to understand what your users want; project managers and product owners to successfully manage others.
