Let us take a look at the role played by a Java developer.

Developer vs engineer?

First, do we mean Java developers or Java engineers? IT is a constantly changing field. Many IT professionals don’t think titles matter.

A Java developer/engineer might be focused on Java applications, but a title such as software developer or engineer could refer to other languages and customer-centric programming.

Java developers often do more than just computer programming. Java developers must be able perform multiple roles.

I agree to full participation in the software development lifecycles. (SDLCs).

Let's now look at the job expectations and responsibilities.

Program architecture
Clear vision is essential for project stakeholders. Java program architects are specialists.


Collect your requirements
Before a Java Developer can start working on a project, they must first gather all requirements.

You could work closely with a stakeholder such as a Project Manager or Senior Java Developer. The discussions will be focused on prioritizing tasks and determining the scope.

Development
A Java Developer starts to write code during the development phase. You can then test your program and make any modifications.

Test
Each feature will be tested and debugged by the Java Developer as it is being built. This is where you will want to make sure that the feature works as it should.

Deployment
For deployment, the code is transferred to a live environment. All changes made during testing should be reversed and re-deployed.

A Java developer must be proficient in at least one of the following enterprise skills or standards to complete the above-mentioned steps of program architecture design:

  • J2EE Framework
  • XML and Xquery
  • Solaris, Linux/Unix Windows Platform
  • Oracle SQL database and JDBC
  • Java XML Parsing, Coding
  • Service Oriented Architecture
  • Perl and Python
  • I Text for RTF Generation
  • Enterprise Java Bean (EJB)
  • Java-based Web Services
  • Java Servlet Technology
  • Maintain and optimize systems

    Java developers' work is not finished when the program has been completed. You can break down software maintenance as follows:


  • Software updates
  • Ensure that your hardware specifications are met
  • Add or Remove Users
  • Add new features
  • Training for End User Documentation
  • Maintaining an Active Testing Environment
  • Looking for code smells
  • Recognizing other programs and using them to improve your system

    These examples are just a few of the many ways a Java Developer can optimize an enterprise program for a client or maintain it for them.

    Each task requires a developer with a unique skill set. You can take, for example:

    Java developers might be more sales-oriented to identify enhancements and present them to project stakeholders

    Preparing and preparing documentation can take hours. It's possible to spend hours creating training materials and documentation for end-users.

    Java developers should expect to spend as much time optimizing and maintaining their programs than they do building them.

    Management of Projects

    Java developers may report to or work alongside a project manager. It is important that they possess the following skills:


  • Pre-planning, discovery
  • Implementing work time
  • Ensuring deadline delivery
  • Reporting
  • Planning for release

    These skills are crucial for project management. You may require more depending on the project or the role of the developers.

    Java developers need to play an integral part in Pre-planning and Discovery.

    Java developers can use project management tools in order to provide reports to stakeholders. These reports give a high-level overview of the project's progress towards completion.

    During the Release Planning phase, the project was tested and debugged. The Java Developer now focuses on timing and market conditions.

    Leading & liaising

    Senior Java developer is responsible for the project's success.

    As a key member, the Senior Java developer plays a crucial role in coordinating with stakeholders and testers to ensure seamless user experiences. Some tasks may be delegated to program architects who are only focused on program architecture.

    The Senior Java developer responsible must be able to understand the overall vision and scope of the project. The Senior Java developer in charge will then need to identify the best people to oversee the project and ensure it meets its deadlines.

    Vendor management

    Senior Java developers can come up with innovative ideas and get approvals from clients before they are implemented.

    This task can also be applied to Java Developers who hold a leadership position within Vendor Management.


  • Conceptualize Vendor Management strategy
  • Set selection criteria and processes
  • Prepare an RFQ questionnaire.
  • Compare and negotiate with vendors


Stay in touch with vendors who like

A strategy to ensure vendor accountability. Java developers must be able to do many things to make a career of it.

  • Companies also seek experience in:
  • Java-based Web Services
  • Relational databases
  • SQL, ORM
  • Test-driven development (TDD)

    Pathways for a Career
