projects they are working on. Some Java developers might need to know how to use a specific
framework or language, while others will be expected to know how to create user interfaces
or work with databases. Some of the most important skills include design patterns, database
design, and queries, concurrency, and multi-threading, performance tuning, debugging, unit
testing, and refactoring.
The developer must have strong proficiency in the latest Java concepts and the
ecosystem surrounding it. Java8 is currently the widely used programming language;
look out for that.
Since Java is an object-oriented programming language, look for developers who are
well-versed in OOPs concepts.
Although Java is a backend programming language, developers must also be proficient
with frontend skills to build enjoyable user experiences. A full-stack Java
developer is an ideal option.
Expertise in ReactJS is crucial as it simplifies frontend development for developers.
It enables developers to describe user interfaces declaratively, removing most of
the legwork from the coding activity and making the code easier to read and
All Java developers must be proficient in data storage, processing, retrieval,
migration to different databases, and have basic knowledge of how to link databases
with the application.
It is a part of the Java language which can be used to develop general-purpose
applications. An ideal Java developer candidate must be proficient in Core Java.
To ensure continuous integration and deployment, Java developers must have DevOps
expertise. Developers must understand programming best practices, how to set up an
infrastructure environment, write scripts, and follow rules.
Git is a vital tool for Java developers; every Java developer should master it. See

Questions to Ask When Hiring Java Developers
1. What are the various access specifiers for Java classes?
ava’s Access Modifiers are designed to specify the accessibility to or the scope of a field,
class, method, or constructor. Java developers can change the access levels as required by
implementing the access modifier. There are four types of access modifiers or visibility
specifiers for Java classes: default, public, private, and protected. A Private Modifier
gives access only within the class, while the Default Modifier provides access only within
the package. The Protected Modifier uses child class to protect the class both within and
outside the package. Last, but not least, the Public Modifier provides access within and
outside the class, and also within and outside the package.
2. What are the benefits of using Spring?
If you are hiring a Java developer, it is important to have a list of questions ready. This
will help you screen candidates and make sure that they are the right fit for your company.
Design your questions in a manner that you can acquire more information and understanding
about their experience with Java, experience with web applications, open-source
contributions on GitHub, experience with JVM, experience as a team lead or project manager,
proficiency with big data technologies, and more.
Simple Testing & Non-Invasive
Testing an application end-to-end with Spring is easy owing to the dependency
injection system. Also, Spring eliminates the need for developers to inherit
specific classes or applications/implementations/executions on any UI.
Fast & Well Organized
The Dependency Injection functionality in Spring makes framework integration easier
and faster while also providing robust support to JavaEE-based apps. Spring also
comes with an MVC Web Framework that helps Java developers build apps using Struts
and the like.
Suitable API & Lightweight
As compared to EJB containers, Spring is significantly lightweight. The light nature
of Spring helps Java developers develop and deploy apps even on computers that
restrict memory & CPU resources. Spring has the capability to translate anomalies in
tech into consistent but uncontrolled exceptions.
3. Does Java have a static class?
Yes, Java has static classes. Java supports Static Methods, Static Classes, Static Instance
Variables, and Static Block. The nested class is defined in the Outer Class while the Inner
Classes can be both static and non-static. You can create a static nested class without
having to create its outer class. Also, a static class has access to only the static members
from the outer class, but the inner class has access to both static and non-static members
of the outer class.
4. What is the Java Classloader?
Java ClassLoader is an object which is used to load Java classes to JVM. It basically refers
to an abstract class from java.lang package that loads classes from multiple resources and
helps load classes at runtime. Your developers will load the classes into the JVM as per
application-specific requirements. Java Classloader typically works with three principles,
i.e., Delegation Principle, Uniqueness Principle, and Visibility Principle. The types of
Java Classloader would include Boostrap Class Loader, System Class Loader, and Extensions
5. How can you connect a Java application to a database?
Java Developers can connect a Java application to a database in a few simple steps
- Register the Driver class
- Establish a connection
- Create a statement
- Run queries
- Close the connection
