How to become a java developer?

Question

Java

I want to become a java developer, I myself don’t understand everything in what area, but I’m looking towards enterprise.
at the moment:
-I know the basic functions of the language (collections, multithreading, io) but without theory, only with OOP everything is fine.
-have experience in developing android applications and a bit of retrofit 2
-basic knowledge of spring boot (handling GET / POST requests)
-understanding of http requests.
perhaps something was written incorrectly.

I don't know how to act. I can’t go for an internship because of my studies, it’s somehow incomprehensible to me with freelancing.

Answer 1

Write some applications to your taste. Simple toys, chat rooms, calculators.
Read about the correct design of the code, write autotests.
Then read the requirements for vacancies and learn the technologies that are listed there.
Ask for an internship. Just because you can't now doesn't mean you won't be able to later. But by the time you graduate, you may already have a confirmed internship agreement, and for this you can walk around in a year or two, find out the conditions, improve the necessary knowledge and agree on the actual device.
PS Well, the most important thing is to learn how to use Google. After all, there are many ready-made answers, and they are all similar ..
