Become a kickass Java developer

Hey campers,

I have a question. We know if someone completes the FCC course, they get junior to mid level expertise in building node applications.

In the same way what projects or apps one should build to get senior level expertise in Java.
Like is there a specific path one could take, or make a specific projects to gain that much expertise?

I don’t know if I fully understand your question.
But why don’t you replicate those projects in Java?
