Java Advantages for Web
Java is the programming language of great development possibilities. Let’s have a look at the reasons to use this language for building your web solutions:
- platform independence – Java-based apps are compatible with any platforms and devices due to its compiled code. It makes Java apps run on any platform and Java developers don’t need to rewrite a Java-apps’ code depending on a platform like Windows, iOS, or Android;
- object-oriented – with Java, programmers can develop modular apps with reusable code. This accelerates development speed and allows delivering apps much faster;
- simplicity – Java is simple to learn, therefore, it’s a good choice for beginners. Besides that, it’s easy to write, compile, and debug;
- effective memory management – memory management in Java is automatic. It has a garbage collector working in the background that deletes the objects once they are not used by the system to clean up the space for new objects. This results in effective memory utilization and prevents memory cluttering;
- extensive Java development community – only on Github there’re 133,680 public repositories for Java, let alone Java forums and groups in social media where Java developers can always find support and resolve the most challenging development issues;
- a wide range of powerful development tools – Java implements Eclipse SDK, NetBeans, JUnit, Jenkins, IntelliJ IDEA, and many other tools that allow building effective and stable apps.
Advantages of Hiring Java Developers for Your Project
When you hire Java experts for your web development projects, you get an immense number of benefits that can easily outweigh any other web development solutions. That’s what you can get.
Obtain High Tech Abilities at Low Cost
There is a range of skills Java developers have to obtain to successfully implement this programming language. Here is the list of concepts an experienced Java programmer should be acquainted with and implement Java ecosystem, concurrency and multithreading, working with SQL queries, data structures and collections, cache coherence and fence instructions, memory management, implementation of Java Virtual Machine (JVM), classloading, optimization of garbage collection.
Simple Development Team Scalability
When building projects with Java, you can scale your Java development teams depending on the project requirements. For this, you need to define which category your Java development project belongs to. It can be web app development, product development from scratch, existing app upgrading with a new functionality, app migration, 3d party integrations, and others.
As the developers proceed with your app development project, you can add or remove the specialists, reducing costs for building your app.
Obtain Access to the Cutting-Edge Technologies
With Java, software developers can improve an app with the latest technologies. For example, Java makes a perfect match for building IoT solutions, it has special tools for working with Big Data, Artificial Intelligence, and Machine Learning solutions.
Above all, Java is a constantly developing and upgrading language. Java creators add new tools, libraries, and frameworks to Java, making it even more robust and easier to implement with the most advanced technologies.
When you hire a dedicated team of Java developers, you free yourself from the necessity to search for suitable candidates, quickly ramp up your software development team, or get deeply involved in product development. Instead, you obtain a team of Java experts who are fully dedicated to your project, while staying self-managed. This way, you can ensure a fast start of your web app development project, get direct access to a unique talent pool, and save on the development costs.
Tips for Hiring Java Experts
It’s not always possible to hire Java developers from the local market. But there are several options on finding them elsewhere. The most viable one is to refer to outsourced specialists. For this, you need to look for a reliable outsourcing company that can provide you with the relevant candidates.
Where to Search for Professional Java Developers
To find reliable and skilled Java developers you have to go beyond just looking for them in Google or any other search engine. Check out professional sites for developers, like Clutch, Upwork, LinkedIn, or social media like Facebook.
A portfolio with case studies will reveal if the selected Java team has already developed apps similar to yours. Then, it won’t be a problem for them to create another one and even with better functionality.
The next step is to conduct technical interviews with the selected candidates.
How to Prepare for Tech Interviews
Online interviews don’t differ much from the offline format. However, they require a little more preparation and attention to detail. Here is what you can do to hold a successful online interview.
Write the App Review
Prepare a brief description of the web app you want to build. Include in the description the main purpose of the application – if it’s an eCommerce app or maybe you want to help your customers to reach any of your services online. And consider what features you would like to add to your web app. They can include AI chats, IoT solutions, online payment, and many others.
This quick app review will help you during the interviews to explain in greater detail what you expect from your app.
Conduct One-on-One Interviews
Have face-to-face interviews with each Java developer you want to hire. It can be just one developer to add to your project or a team of developers who assume the responsibility for an entire project.
Individual interviews help to better understand:
- if it’ll be comfortable to work with the chosen developers;
- how communicative they are;
- if they are willing to help you solve your application development problem;
- what’s their development experience and area of expertise.
Ask the Right Questions
Try to avoid “yes/no” and leading questions when conducting interviews.
“Yes/no” questions require a short negative or positive answer, they don’t let you learn more about the candidate’s experience. For example, instead of asking, “Do you work with mobile development?” you could ask, “What’s your experience in mobile app development?”
Leading questions help the candidates to understand the answers you’re expecting. For example, instead of saying “How do you feel about working individually without direct management for some time?”, you can ask, “Tell me about your habits and traits at your workplace.”
Some example questions you could ask during your interviews:
- What’s your best software development skill? In what projects did you have to implement it?
- Tell me about a serious issue you had to handle quickly in a project. How did you resolve it? What was the outcome? What did you learn from that situation?
- Have you ever had a situation when a customer wasn’t satisfied with your work? What was it about? How did you resolve it?
- Have you ever missed a deadline? What was the reason? What actions did you take to handle the issue?
This type of questions helps establish good interpersonal communication and allows you to learn more about your potential candidates’ experience and their working style.
Hiring dedicated Java developers for building web apps provides an extensive number of advantages, including implementation of the latest technologies at low cost, simple team scalability, reduced development and project launching time, and many others.
To hire Java developers with the appropriate qualifications, you can follow some practical steps which include:
- a thorough search for the candidates and checking their profiles and portfolios;
- preparing a brief description of your web application and its functionalities;
- conducting individual interviews with properly asked and relevant questions on developers’ experience and tech stack.
