With its 27th birthday approaching, Java has proven to be a reliable and versatile programming language, consistently ranking among the most popular and widely used. From its humble beginnings as a language for digital devices, to being used by over a million software developers worldwide, Java has come a long way. 

According to the US Bureau of Labor Statistics, over 1,469,000 software developers are in the United States. 35.35% of developers use Java, making it one of the world's top five most widely used programming languages.

Join us as we dive into the world of Java development and discover the benefits, responsibilities, and opportunities that come with being a Java Developer. So, whether you're a coding pro or just starting, keep reading to learn everything about Java!

What is Java?

What is Java?

Before discussing java developers, let's first understand the basics of the language. 

Java is a general-purpose, class-based, object-oriented programming language with low implementation dependencies. It is a computing platform for developing applications. As a result, Java is quick, secure, and dependable. It is widely used for application development in laptops, data centers, game consoles, scientific supercomputers, cell phones, and other devices.

So, what is Java Platform?

The Java Platform is a collection of programs that enable programmers to efficiently develop and run Java programming applications. It contains an execution engine, a compiler, and a collection of libraries. It is a collection of software and specifications. 

Why is Java popular?

Why is Java popular?

According to Statista, despite the availability of numerous other programming languages, Java remains one of the most popular among programmers. Why is this the case? One of the primary reasons for this phenomenon is that Java is platform-agnostic. A Java program can run on any device with a Java Runtime Environment installed, even if it was originally designed for a different system. 

Java is also relatively easy to learn, code, compile, and debug compared to other programming languages. Java also earns points from developers for its ability to adapt quickly to new uses. Java is consistently ahead of the competition in supporting new technologies or trends, thanks to frequent new version releases and hundreds of new libraries shared by developers worldwide.

What is a Java developer?

A Java developer (also known as a "Java engineer" or "Java dev") is a specialized IT professional who works with Java. Java developers are in charge of creating software, websites, and applications in Java.

Let's now look at what java programmers do.

What do Java developers do?

The workday of a Java developer differs depending on whether they are an entry-level, mid-level, or senior developer.

Entry Level Java Developers

Entry-level Java developers have little professional experience. They devote their time to:

  1. Enhancing Java programming abilities
  2. Writing fundamental code
  3. Basic bug fixes
  4. Developing end-user documentation to assist users in navigating the system

Mid-Level Java developers

A mid-level Java developer has 2 - 5 years of professional experience and is well-versed in a company's IT architecture. Because their skills are more advanced than those of an entry-level Java developer, they spend their working hours as follows:

  1. Creating more complex code
  2. Fixing more complex bugs
  3. Conducting (or supervising) testing
  4. Java project planning
  5. Making user documentation
  6. Collaboration with vendors
  7. Management of junior developers

Java Senior Developers

A senior Java developer has at least 5 years of experience, a thorough understanding of a company's IT systems, and expertise on various projects. They spend their working hours:

  1. Advanced Java project planning, consulting, and review
  2. supervising the work of junior staff members
  3. Collaboration with vendors
  4. Supervising the financial aspects of development

Roles and Responsibilities of Java Developers

You, as a recruiter, would determine what your Java developers do; however, most Java developers perform similar roles, such as:

Collaboration with IT Vendors

They collaborate with vendors who provide infrastructure, software, and platforms to your company (for example, infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and software-as-a-service (SaaS) vendors). In particular, Java developers may need to:

  1. Build relationships with current vendors.
  2. Create criteria for new vendors.
  3. Investigate vendor options and keep an eye on the market for new technology.
  4. Consider offers and negotiate on your company's behalf.
  5. Prepare the Request for Quotation (RFQ) and bid documents.

Creating Code

Java developers' most essential task is to code. You can use this code in a new project, ongoing updates for an existing project, or bug fixes.

Code Testing

Once they've written the code, they'll need to test it with code review tools to identify any problems. They perform functionality testing, static code testing, unit testing, and single-user performance testing on their code. 

Code Distribution

A Java developer must deploy code to deliver it successfully to users.

Troubleshooting Software Issues

Java developers are responsible for resolving errors in their programs because no project is ever perfect. They must diagnose problems, create a solution, and deploy it.

Understanding the Architecture of a Program

An experienced developer must thoroughly understand your company's programs, IT infrastructure, and program architecture. Understanding program architecture is essential because it will influence how they develop new projects.

End-User Documentation Creation

Java developers need to create end-user documentation to assist people using the program. This documentation includes installation guides, user manuals, release notes, and training manuals.

Application Security and Performance Monitoring

Finally, they should keep track of their projects at all times. Continuous monitoring enables them to identify potential errors, track usage statistics, and identify changes you could make to improve the program for users.

Skills Java Developers must have

You must check a few technical and soft skills before you recruit a java developer. These are:

Technical Skills

Java (Core)

Core Java Skills are the foundation of any successful Java Developer. You must look for the following Core Java skills:

Skills in Object-Oriented Programming

The Object-Oriented Programming approach introduces a class and object-oriented coding style that deals with inheritance, encapsulation, abstraction, and polymorphism concepts. OOP aims to connect data and functions to improve code stability and safety.

Design Patterns in Java

Design patterns in Java are standard solutions to routine problems encountered during the software development life cycle. Every Design Pattern serves as a blueprint for customization to solve any design problem in any code during software module development.

Java Abstract Classes

Java Abstract Classes assist developers in achieving abstraction. In object-oriented programming, abstraction reduces code complexity by displaying only the relevant details of the objects used in the program and improves code readability. 

Java interface

In Java, an interface is an advanced level of abstraction. The interface in Java enables a more efficient and effective method of achieving abstraction in Java.

Java Serialization

Java Serialization is a concept that deals with converting objects into a byte stream to transport them from one Java Virtual Machine to another and recreate them in their original form. Serialization allows developers to meet a variety of requirements in real-time programming.

Java Build Tools

Depending on the task, developers must use a specific tool. Understanding the terminology of Java Build tools is useful for a Java Developer because Java Build tools are programs that automate the creation of executable applications from source code. Maven and Gradle are tools that your potential java developer for hire should be familiar with.

Web Technologies

Web technology makes it simple and quick to create dynamic web content. Understanding the technique of establishing communication between multiple computer systems via markup languages is aided by a better understanding of Web technology. It provides a means to interact with the host for information, similar to websites. It makes use of HTML, JQuery, and CSS.

Java Web Frameworks

Java web frameworks are the best-in-class solutions for developing a mobile application with the most features and the least amount of code. They enable the standard development of web applications such as web services, web resources, and web APIs to build and deploy web applications on the World Wide Web. Spring MVC and Play are the best frameworks java developers for hire must know.

Java Testing Tools

Java Testing Tools enable developers to test the JSP pages and Web Apps using an interface that does not require to launch of the application in a web browser. They help with various test activities such as planning, requirements, building, testing, defect logging, and testing analysis. Selenium and TestNG are testing tools.

Big Data

Big Data has become a trillion-dollar industry, and traditional data processing software cannot handle such massive amounts of data. Knowing Big Data technologies enables developers to analyze and extract information from large amounts of data. Hadoop and Spark are two powerful Big Data technologies.

Java EE Components

Developers use Java EE Components to create server-side applications. One of the most common challenges that enterprise developers face is dealing with requests from web-based clients. To address this issue, Java EE includes the Servlet and JavaServer Pages APIs, which enable methods for logging activities using cookies on a user's browser and simplify these issues while providing the best solution. Servlets, Java Beans, and Java Server Pages are the most important Java EE components.

Soft Skills

Soft skills include, among other things, people skills, communication skills, character, and social intelligence, which enable people to navigate their environment, work well with others, perform well, and achieve. Soft skills for Java Developers include:

Excellent Communication Skills

Good communication skills include active listening, which involves paying close attention to the person speaking to you and attempting to adapt your communication style to your audience to convey your message more effectively. You can test this skill in your potential candidate's first round of interviews.

Willing to learn

Knowledge is limitless. Your potential Java Developers should always be willing to learn new technological advancements and keep themselves up to date.

Team Work

The effort of a team to achieve a common goal and complete a task most efficiently and effectively is referred to as teamwork. Your java developers for hire should be good team players to ensure smooth functioning.

Work Ethics

The belief that hard work and dedication have a moral advantage and an inherent ability, virtue, or value to enhance the character and individual abilities are referred to as work ethic. Before you recruit a java developer, make sure to give them situations and asses how ethical they are based on their answer.

Interpersonal abilities

Interpersonal skills are the characteristics and behaviors a person employs to interact effectively with others. Again, before you hire a java developer, give them a situation to see how they react to it.

Cost of hiring Java developers

  1. Java Developers with 1-3 years of experience in the USA costs an annual average of USD 93,118, according to Glassdoor. 
  2. Entry-level developers are expected to cost an annual amount of USD 73,839
