Java Framework: An Overview
Java is among the languages that strike the mind while thinking of
creating high-end, futuristic, highly secured, and scalable
applications. It features predefined functions and classes to
process input and deliver outcomes that work well on all devices.
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 detection. The availability and accessibility to a large
standard library make the entire development task super easy.

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
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
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
Shortlist Candidates Based on Their Experience and Portfolio
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
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
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
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
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 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
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
Simply put, JDK is used for the development tasks, whereas JRE
is required to run the code. And, JVM is the core of this
Q.3: What is Data Encapsulation and Garbage Collection in Java?
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.
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.
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.
Making Solely Cost-based Decisions
The programming world is full of coding experts. You can definitely find someone offering low-cost services, but they may not provide A-1 quality support. There will be a higher probability of errors in the code and inefficient functioning of the apps. Therefore, never make cost-based decisions; Instead, determine the developer’s skills and knowledge to make profitable decisions.
