JAVA DEVELOPER

Java Developer

A?Java developer?is a specialized programmer who collaborates (working with two or more people) with software engineers and web developers to integrate Java into applications, software, and websites. He is responsible for developing a robust code that can be easily integrated with the larger systems. Hence, he plays a vital role in the software development life cycle. He serves many duties (from designing to testing) during the software development such as design, development, and management of Java-based applications.

Roles and Responsibilities

The roles and responsibilities both are different terms. These terms are proportional to each other. The role (designation) decides what duties you have to perform in an organization. While the responsibilities include?functions, duties,?and?obligations.?Let's discuss the role and responsibilities that a Java developer.

Java Developers Roles

The role of a Java developer is highly responsible. An organization categorizes the Java developer role in the following three levels:One who is fresher or having 1- or 2-years' experience in?Java?or any programming language may get this position. The?junior Java developer?position does not require too much knowledge about Java. But one should have the basic knowledge of object-oriented programming, along with core and advanced concepts with?Servlet?and?JSP. A little bit of knowledge about front-end development.

Anyone who has more than 5 years' experience in the working of Java technology may get this position. The?senior Java developer?positions are highly responsible for project development. They perform lots of responsibilities to develop the project. They work with junior level staff.

One who has more than 10 years' experience in Java may get the position. It is a highly responsible job. The?lead Java developer?design and recommend technical solutions for IT-related issue. The lead developer works with the senior developer and ensures the quality of the product, identifies the issues that may affect the project delivery and also monitors the junior level staff.

At the last of this section, we will discuss the road map to become a successful Java developer.

Java Developer Responsibilities

A Java developer serves the following responsibilities:

• Design and implement Java application phases.
• Participate in architectural and software development activities.
• Conduct software analysis, testing, programming, and debugging.
• Recognize the production and non-production application issues.
