If you are looking to find the right coders for your unique project needs, read our comprehensive guide to make an evidence-based decision. Developed in 1995 by James Gosling, it¡¯s a platform-independent language wherein we can derive code once and run it on other platforms (that support Java). This is an extremely simple and reliable programming language in which not much effort is required for error
- 2. detection. The availability and accessibility to a large standard library make the entire development task super easy. What Are The Functionalities Of Java Developers? Java programmers are accountable for developing feature-rich Java-based applications. Here are the basic roles and responsibilities of Java developers. They check the idea¡¯s feasibility and plan to transform it into reality. They perform coding jobs to create a well-performing app. They conduct tests and debug to identify and resolve errors in code. They keep abreast of the latest tools and updates in the tech world. Apart from these, developers offer round-the-clock and after-development support if you encounter any difficulty running the application. Steps To Hire The Right Java Programmers When you hire Java programmers, ensure they have the right Java skills to complete the project successfully. Here are some steps that can simplify your hiring process. Outline and Share Your Java Development Needs The process begins by determining your application¡¯s requirements. Describe job specifications that are aligned with your organization¡¯s goals, long-term objectives, specialized features, and unique user requirements. Once done, share the description on various job platforms, like LinkedIn, ZipRecruiter, and freelance platforms (such as Upwork, Fiverr, etc.). In addition, you can approach the growing Java community for reliable support, knowledge, and information. Identify the Right Hiring Model for Your Needs You must finalize the right engagement model when hiring an employee. There are basically two working models, which are as follows- Full-time dedicated employees: In this model, you Hire Java Developers as your full-time employees. You pay a fixed salary to them based on their experience, scope of work, and other factors. Outsourcing or freelancing: In this type of engagement model, you pay for the time the development agency has worked. You assign the project to them, and they will complete it within the pre-decided tenure. Shortlist Candidates Based on Their Experience and Portfolio
- 3. All potential developers undoubtedly bring their impressive skill sets to the table. You should be cautious while examining for their reliability. Shortlist them out, considering your particular needs, portfolio, and experience. You can, either manually or using the software, screen the resumes of developers and weed out applications that don¡¯t fulfill your specific benchmarks for the developer¡¯s role. Rest can be carried forward for the next technical assessment round. Conduct Technical Assessment During this stage, you must interview shortlisted Java developers to determine their competency and technical skills. Ask technical questions on core Java techniques and other associated technologies, concepts, and frameworks. Also, discuss the tools they are well-versed with, such as ORMLite, CachingTouch, Corona SDK, etc. It helps you fill the positions with the best development enthusiasts from the global market. Send Offer and Sign NDAs Finally, send an offer letter to the employees you chose for the job role. The letter must include all the terms and conditions, finalized payment terms, working period and mode, notice period, etc. Ensure the employee understands the company¡¯s policies well without any ambiguity. Also, sign non-disclosure agreements to safeguard your organization¡¯s important data and other confidential information. These steps help you make a wise choice when you hire dedicated Java developers. Let¡¯s proceed further to determine some significant skills a Java developer must possess. What Skills To Look For When You Hire Java Developers? Each developer holds different levels of technical knowledge and skills, as they would have worked for different companies and their Java development projects. Here are some usual skills a proficient developer must hold- Solid Proficiency in Java When you hire Java programmers, make sure they have a solid understanding of Java and its key concepts. They must know how to effectively use Java frameworks (like Struts, Spring, Google Web Toolkit, etc.) and libraries. It makes complex tasks easier, improves code quality, and reduces development time. Good Database Skills
- 4. Almost all applications utilize data stored in databases. Therefore, developers must know how to access, retrieve, manage, and manipulate data in different databases. When you hire dedicated Java developers, examine their knowledge of Java Database Connectivity (JDBC) and Structured Query Language (SQL). It helps in executing queries and interacting with databases in a better way. Knowledge of Object-Oriented Programming Since Java is an object-oriented programming language, having a deep understanding of this concept is mandatory. Developers must know the purpose of objects, user-defined classes, inheritance, polymorphism, abstraction, and encapsulation. It helps develop performant applications with the latest features that run nicely on all the platforms. Effective Memory Management A good Java developer knows the best practices for effective memory management. If this concept is not properly managed, it results in inefficient and unstable code. So, ensure the potential candidate knows the Java Memory Model, practices to avoid memory leaks, and usage of Java Garbage Collector and object pooling. Understanding of Version Control Systems Version control systems (VCS) are responsible for tracking and handling changes in digital files over time. Such systems allow coders to work parallelly on the same project and merge changes to minimize conflicts and frittered resources. It ensures proper team collaboration worldwide and speeds up product delivery. Technical Questions To Ask During An Interview Asking technical questions is essential to gauge the developer¡¯s knowledge and competencies. So, here are a few questions you can include during the technical interview round. Q.1: Name some Java development frameworks and their features. Expected Answer: The developer must know that Java frameworks are sets of pre-written codes to which one can add their code. Here are some of the most commonly used Java frameworks that they must know: Spring: A candidate must know about the Spring framework, which is a powerful, lightweight framework that can be employed for layer implementations in real-time apps. This is a properly crafted web MVC framework that supports Aspect-oriented programming. Apache Struts: Another framework they must be aware of is Apache Struts, an enterprise- level framework that enables coders to create simple-to-use and maintain Java apps. The
- 5. framework provides centralized configuration and helps streamline the development process. Hibernate: Hibernate is a mapping framework that provides clear communication between Java language and RDBMS (Relational Database Management Systems). A developer¡¯s knowledge of Hibernate ensures enhanced productivity and easy maintenance of codes. Google Web Toolkit: This is an open-source framework that candidates must know. It allows coders to write client-side code and install JavaScript for free. Using this developer- friendly framework, one can easily and efficiently code complicated browser apps. Q.2 Explain the JRE, JVM, and JDK concepts in Java. Expected Answers: The developer must know these core concepts in Java for better project development. JDK: JDK stands for Java Development Kit that offers tools and libraries to assemble, debug, and run a Java Program. It basically features a Java Runtime Environment, loader, compiler, document generator, and other tools for the swift execution of Java applications. JVM: JVM stands for Java Virtual Machine and is accountable for turning the byte code into a machine-specific program. This framework ensures efficient memory management and garbage collection while implementing Java code one after another. JRE: JRE stands for Java Runtime Environment, which is responsible for providing a platform to run a Java program. That means it is only helpful for end-users. Simply put, JDK is used for the development tasks, whereas JRE is required to run the code. And, JVM is the core of this programming language. Q.3: What is Data Encapsulation and Garbage Collection in Java? Expected Answer: Data Encapsulation In Java, data encapsulation involves bundling data and methods together into a single unit. It serves as a protective shield that hides data in one class from other classes. It ensures increased flexibility, reusability, and easy code testing. Garbage Collection Java Garbage collection is an automated procedure for deleting no longer required codes. It frees up the memory allocated to ¡°not-needed¡± objects for easy and efficient code development. Java features four different types of Garbage collectors: Garbage first (G1), Concurrent mark-and-sweep, Serial, and Parallel Garbage Collector.
- 6. Mistakes to Avoid While Hiring a Candidate for the Job Overlooking the Candidate¡¯s Experience Since locating the right Java developer is tricky and time-consuming, you must not settle for any candidate to fill the position urgently. Never disregard the experience factor. Make sure the developer has expertise working on a project similar to yours. Failing to Conduct a Technical Interview When you Hire Java Programmers , don¡¯t forget to conduct a technical interview. Technical rounds help acquire a clear picture of the candidate¡¯s skill sets, capabilities, and knowledge of the specific technology. ` Restricting Your Talent Pool A remarkable thing about the present tech world is that you can hire talent from the whole world. So why restrict your search within geographical boundaries? Use different online job platforms to share your requirements and attract global talent.
