Responsibilities of Java developer
Before we look at Java developer skills, let's first discover the responsibilities of these developers when they join your team. Some of their responsibilities include:
- Understanding the language of Java build tools
- A Java expert must identify and resolve any technical issues
- Java developers must design, implement, and maintain Java-based applications
- The applicant must analyze user requirements to determine the business objectives
- Manage Java and Java EE application development
- The developer must analyze user requirements to determine the business objectives
Top Java developer skills to look for when hiring
Java developers can be found across various countries, but how would you identify the right candidate from a large number of Java developers available? To ensure that your project meets all the demands and is up to the mark, you need the right tech stack and resources to achieve it.
Below we have mentioned the top eight skills that you must look for when hiring Java developers.
1. Object-Oriented Programming
Object-oriented programming is one of the top Java skills to look for when hiring. Object-oriented Programming is fast and easy to execute and helps keep the Java code DRY "Don't Repeat Yourself".
Some of the significant OOP characteristics include:
Abstraction:
Abstraction characteristic helps the Java developer to hide irrelevant data about an object to reduce complexity and enhance efficiency.
Encapsulation:
Encapsulation binds data with the code that manipulates it and protects it from external manipulation.
Inheritance and composition:
This characteristic allows the developer to reuse elements and combine multiple objects to create a new object.
Polymorphism:
Polymorphism authorizes the use of a single interface regardless of the underlying forms.
Hence, object-oriented programming concepts emphasize the use of objects, classes, and inheritance to organize and structure code. Java heavily uses OOP concepts to provide a powerful and flexible programming platform.
2. Familiarity with web technologies
If your business often has web application requirements, finding a developer familiar with web development becomes a must. The web technologies like Java server pages allow Java developers to build engaging, rich, and dynamic web applications.
For Java web developers, the fundamental skills required are Servlet, JSP, and Java EE.
57% of internet users say they would not suggest a business with a badly designed website on mobile, which is why excellent web services are in demand. As a result, RESTful web services are one of the most commonly used APIs in the world of web services.
Some of the Java tech stacks for web development are:
Angular:
The angular framework is a popular front-end web framework that provides various Java development tools and features for development.
This technology helps to create a single-page app and can be used for creating desktop, native, and advanced web applications.
HTML, CSS, and JavaScript:
HTML creates the core elements of web pages, CSS helps style these pages, and JavaScript adds interactivity and dynamic behavior to these web pages.
Servlet API:
Servlet API provides several interfaces and classes to create and run web applications and offers platform-independent service to the users.
3. Design and architecture
Design and architecture are crucial parts of any business growth. Whether it is a web page, web app, or mobile application, these two aspects add beauty to it.
To ensure that your solutions are unique and provide an excellent user experience, you need a Java developer who fully understands the design and architecture and its importance.
Design patterns can be classified as follows:
Creational design patterns:
These patterns include Singleton, Factory, Abstract Factory, Builder, and Prototype, which deal with object creation mechanisms to create objects suitable for the situation.
Structural design patterns:
These patterns focus on the composition of classes and objects to form larger structures. They help in simplifying the design and identifying relationships between different entities.
The Adapter, Bridge, Composite, Decorator, Facade, Flyweight, and Proxy patterns are all examples of structural patterns.
Behavioral design patterns:
These patterns deal with the communication between objects and how they work together to perform a task. They are concerned with algorithms and the assignment of responsibilities between objects.
The Chain of Responsibility, Command, Interpreter, Iterator, Mediator, Memento, Observer, State, Strategy, Template Method, and Visitor patterns are all examples of behavioral patterns.
To create robust, scalable, and maintainable software applications, Java developers must be able to translate these designs into functional architecture.
Developers with this skill can make more informed decisions for the software application's design while considering performance, security, scalability, and usability.
Further, such Java engineers can create software programmers that meet the needs of the client and serve as a strong basis for future growth and development.

4. Soft skills
On the one hand, considering the technical Java programming languages skills is essential; on the other hand, it is equally crucial to check their soft skills. If they cannot align with your business goals and project needs, you may face problems in getting your work done.
Some of the vital soft skills to consider when you hire Java developers are:
Teamwork:
Java developers will be working with you and your people in the team. Therefore, they must possess the skills to cooperate and work with other team members.
Good communications:
As they will not be present in the office, you need to ensure they have strong communication skills so that you can easily pass on the project needs and contact them in case of discussions.
Time management:
Time management is one of the foremost soft skills to consider as they should be able to meet the project deadlines without compromising quality.
As Java is one of the most popular and needed programming languages, you will always be in need of it. But did you know that 55% of CFOs state that their greatest challenge in hiring professionals is choosing a candidate with the right soft skills?
