How many Java projects have you worked on during your development process?

The number of Java projects I have participated in depends on my experience and career stage. For example, at the junior level, it is usually 1-2 educational or small commercial projects, where I familiarize myself with the basics of the language and frameworks.

At the middle level, there are already several projects (3-5 or more), including more complex tasks, working with databases, multithreading, web services, etc.

It is not so much the quantity that matters, but the depth of understanding and experience in solving real-world problems within projects.
