You will hardly find any applications that don’t need Java installed to work properly in today's world. From simple laptops to complex data centers, game consoles, scientific supercomputers, cell phones, to the internet, everywhere you look, Java is everywhere.
In the world of computer programming, Java is one of the older languages. In 1995, Sun Microsystems developed it on the syntax of C and C++. Today, Java is a part of Oracle.
Java is a concurrent, class-based, and object-oriented programming language. Java has several benefits because of its inherent linguistic design. This attracts IT giants to build their programs and applications using Java. Some of the benefits of using Java are:
Fast processing speed: Thus, it is loved by any Android developer
It is a statically typed language: It gives greater safety and stability to the applications as compared to the other programming languages.
Easy to find resources: Most developers start their career by learning Java which means, there is no shortage of resources for companies to hire.
So, who is a Java developer?
A Java developer is a programmer who is an expert in Java and collaborates with other developers and software engineers to integrate Java into the application, software, website, etc. A Java developer is an important member of the software development team and is crucial throughout the product life cycle. They have the most critical role of identifying and analyzing any issues and addressing them at the right time. They also need to collate and document user requirements, quality assurance, testing, etc. A Java developer needs to be well versed with technologies like Enterprise Java Bean, J2EE framework, Java Servlet Technology, Java-based Web services, I Text for RTF Generation, Perl and Python, Service Oriented Architecture, Java XML Parsing, Coding, XML, XSL, Xquery, Oracle Database SQL, JDBC, Linux/Unix Windows Platform and Solaris, etc.

Different Types of Java Developers
Java developers usually work as a team in any IT company. Each organization has its organizational structure and depending on that, a Java developer can be a part of a small project team or a large single IT team. But the most common structure followed in an Agile environment is many small IT teams who work on different projects. A Java developer can either report to a project manager or the overall IT manager who reports to the CIO or a senior IT leader. Depending on their expertise and years of experience, organizations hire Java developers at different levels. These are typically:
- Entry-level Java developers
- Mid-level Java developers
- Senior Java developers
The responsibilities change from one level to another. For example, an entry-level Java developer may need to work on program architecture and put maximum time into maintenance and optimization.
On the other hand, someone at the senior level may be responsible for overseeing the project's overall functioning and managing the team. A typical team of Java developers may have different titles like Software Engineers, Project Managers, and Design Leads.
