Benefits Of Java
Java was developed by Sun Microsystems and post its release in 1995, it has been an integral tool for many software development environments for the variety of use cases it serves, contributing to its ongoing relevance. Some of the benefits of using Java are discussed below:
1\. Platform Independence- Write Once, Run Anywhere! (WORA)
Java enables developers to write once, run anywhere, meaning that by writing code once, they can run it across any device, hardware configuration, or operating system. Any device with a Java Virtual Machine (JVM) can run Java apps compiled into bytecode. This minimizes development cost and time by eliminating specific modifications for each operating system, making Java’s portability a boon for enterprise apps, cloud computing, IoT devices, and Android development.
2\. Minimal Written Code Required
With its extensive standard library known as Java API, Java simplifies a wide range of programming tasks, including networking and GUI development. As such, the amount of code developers need to write themselves is minimal.
3\. High Performance
Java supports multi-threaded programming, meaning it can efficiently handle multiple tasks concurrently through multiple threads, making it perfect for applications which demand high concurrency levels, ensuring there are no compromises in user experience and interface.
4\. Coding Efficiency and Accuracy
Java ensures code accuracy and robustness with its in-built capability to detect issues in the early stages of code execution, making the detection efficient and timely for a streamlined development process.
5\. Security
The Java security manager and other extensive security APIs protect applications from potential threats, violations, security, and data breaches, making Java a non-negotiable tool for building robust and secure web apps.
6\. Java Cloud Computing
Java supports microservices architecture, and its platform independence and portability make it easier to deploy and scale applications in cloud environments. Businesses can leverage Java (and its ability to integrate with containerization technologies) to develop and deploy solutions on popular cloud platforms like Google Cloud, AWS, and Microsoft Azure.
7\. Enterprise Dominance
Java’s scalability and stability make it a widely used programming language in enterprise environments with its Enterprise Edition designed specifically with enterprise features.
What Does a Full-Stack Java Developer Do?
A full-stack Java developer writes code for the frontend, backend, and database layers of an application, facilitating end-to-end development. They are responsible for converting user and business requirements into fully functional applications, managing the user interface, server-side development, logic, database, and optimization. Discussed below are their main roles and responsibilities:
Frontend Development

Best Practices For Hiring Java Developers
Discussed below is the step-by-step process of hiring Java developers for your next project, ensuring an exact expertise match:
Step 1: Define Project Requirements
Define clearly what your project requirements are and what is your goal for hiring Java developers- be it enterprise development nuances, implementing security measures, database management, frontend or backend development, cloud migration, specific integrations, or legacy modernization. Defining project requirements will help you identify the skill gaps in your current team and search for the right expertise.
Step 2: Establish Candidate Expectations
Create a job description to hire remote Java developer that establishes the skill requirement for the role, project scope, complete project vision, and the impact the outsourced professional’s expertise will have on the business to find the right expertise beyond a list of generic skills.
Step 3: Connect With Top Talent Globally
Java development outsourcing gives you the opportunity to tap into the vast pool of Java development expertise across the globe, going beyond your physical location to improve your likelihood of finding the right fit for your niche project requirements. Connect with IT staff augmentation companies that provide Java experts for hire on a project-by-project basis, bringing diverse expertise onboard to cater to dynamic market requirements. You can also connect with professionals through job boards, recruitment agencies, and focused technical communities.
Step 4: Skill Assessment and Interviews
The best practices for hiring Java programmers include assessing their technical skills, theoretical knowledge, and problem-solving capabilities. With platforms like Codility or any other, you can assess all these dimensions of a candidate’s eligibility. Additionally, giving them live coding challenges can help understand their ability to apply theoretical knowledge to solve real-world problems. Pair programming sessions can help assess them for their teamwork, collaboration, and how they make the most of their strengths.
While interviewing shortlisted candidates, structure your questions in such a way that they go beyond technical expertise, and assess the candidate’s cultural fit, teamwork attitude, and problem-solving capability. Include questions from code completion tasks, specific Java frameworks, nuanced Java concepts, architectural design, and their past experiences to determine if they are the right fit for your project.
Step 5: Onboarding Java Developers
You can onboard your selected Java developer from an IT staff augmentation company ↗ within 24-48 hours and kickstart development right away. The ideal outsourcing partner will ensure its dedicated Java developers set up remote project management tools for efficient and timely collaboration and work towards completing the project they were hired for to get you ahead of competition.
Why Is Java Development Outsourcing Widely Preferred?
The global software development market is expected to grow at a CAGR of 11.5% from 2023 to 2028, according to the Software Development Outsourcing Market Analysis Report ↗ by the Global Market Estimates. These figures bear testimony to the growing preference for outsourcing software development, the benefits of which are discussed below:
1\. Flexibility
Outsourcing gives you the flexibility to hire Java developers or hire a dedicated development team ↗ on a project-by-project basis, enabling you to respond to evolving market and user demand easily, upsizing or downsizing their resources according to the need of the hour.
2\. Cost Efficiency
If you hire Java programmer from an IT staff augmentation company, you only need to pay for the short-term contract during which the Java developer will directly report to you and complete your project. This eliminates the need to pay monthly salaries and invest in ongoing salaries of an in-house team member even when there is no project need. It is like hiring a freelance Java developer based on what and when you need with ensured result quality and credibility across industries. Additionally, you can save on operational costs and in-office expenses necessary for in-house teams.
3\. Time Efficient
In-house hiring yields desired results over sustained periods of time as the team begins to accumulate institutional expertise with every project they work on. Additionally, with evolving project requirements and fast-paced demands, it is not possible to hire an in-house Java developer instantly in response to an on-spot requirement. This is where outsourcing dedicated Java developers helps with its quickness and efficiency in matching vetted professionals with the business, helping them cater to short-term project requirements with instant hiring and onboarding.
4\. Access To Global Top-Tier Talent
Outsourcing Java developers gives you access to top-tier talent across the globe, enabling you to find the right expertise tailored to your project needs. Additionally, you can access top-tier talent at the most reasonable rates, as hourly prices vary across countries. One of the best countries to hire affordable and skilled Java developers is India, where the hourly cost starts for hiring Java developer starts at $15, democratizing access to top talent from a diverse pool of skilled professionals for businesses of all sizes.
5\. Competitive Edge
Hiring Java developers on an outsourcing basis enables you to gain a competitive edge by responding to evolving user demands as they come and get ahead of the competition by ensuring you have access to the right expertise at the right time and development happens round-the-clock.
