Java is widely used and ranks fifth among the most popular programming languages. Java celebrated its 15th-anniversary last year, i.e. in 2020. It is now widely used, as it has always been. It is a compiled language that does not restrict object code to a single processor or computer, making it an excellent choice for cross-platform software such as web applications and server code.
Java is also the most widely used programming language for developing Android apps. It’s also popular in cloud systems, deep learning environments, and Internet of Things technology. Java developers must have a wide range of skills, from a thorough knowledge of the basics to understanding the most current developments. Aside from the language, Java developers must consider how the programming process works and how to handle the environments in which it is executed.
Java is used by about 40-50 per cent of programmers worldwide. Java developers face fierce competition. To stand out from the other programmers, you must be a skilled Java programmer.

Who is a Java developer?
A Java Developer is in charge of designing, developing, and managing Java-based software. Since Java is so commonly used, especially among large organizations, everyday roles vary greatly, including having a specific programme or operating on many at the same time.
As a Java developer, you would most likely be part of an IT group. Based on how the company is organized, you can have a single IT team or several smaller IT teams that focus on individual tasks. This second approach is often used in Agile settings.
The Java developer can report to a senior project manager or overall IT manager, who then reports to the CIO or another old IT head.
Employers also recruit Java Developers based on their skills when searching for new employees. Usually, job postings have the following designations:
● Java developers who are only starting out
● Developers at the mid-level
● Senior Java programmers/developers
Early in her career, one Java developer may be delegated to work on application design. At the same time, a senior-level Java Developer may be responsible for the project’s overall operation, including maintaining streamlined architecture and overseeing teams.
