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.

  • Lead Java Developer (Higher Level)

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.
