What is the development plan for Java Developer?

Question

Java

Hey !
Help to make a career development plan, or just share your thoughts (indicate your experience).
My experience is 1.5 years as a tester (auto-tests in Java), and now I got a job as a Java junior developer (code generation project). I know Java Core and OOP with confidence. There is a nuance, I am 32 years old, i.e. there is not much time to try everything in a row .. Now I thought not to rock the boat, for 2 years to deepen my knowledge in Java .. Maybe back-end .. I'm also thinking about trying android development. BigData somehow does not attract me.
Becoming a developer is my old dream (I like to write code).

Answer 1

The general plan is as follows:
1) OOP principles,
2) Java Core (input, output, multithreading in all forms, etc.), design patterns, and
3) then it doesn’t really matter in what order. You can even in android, even in the backend, anywhere)
For the backend, it makes sense to look at working with the database and popular frameworks like spring.
