Practice and in-depth study of Java?

Question

Java

Having scoured the Internet, I did not find any sensible advice about self-learning java, further than online courses like sololearn, codecademy etc.
Do not tell me where to move further in the study, perhaps some hidden courses, or how it is normal to get at least some kind of practice, and not just the same type of tasks on similar sites with courses.
I will be grateful.

Answer 1

Depends on what direction you are going to develop. Let's say a backend, a couple of links, when I looked for the sake of interest, for a start it seems to be not bad, they explain the basics
of the Java 1
web service Java 2 web service
for theory, read something interesting, from all the blogs that I once read, this is very a lot of topics covered
. You can, for example, write some kind of your own service (select interesting music for you, for example), which will have a normally separated backend and frontend, that is, for example, you will have a web interface, and the ability to add mobile applications (using your server API). Here, REST and services and everything can be uploaded to the cloud. You can also start looking towards the spring projects frameworks andtrend pieces
The main desire is to develop and everything will work out !!!

Answer 2

Do you think that each of your TK will be unique and entertaining, and not the same type and boring?

Answer 3

look at hexlet.io, there is a slack chat, write simple 2D games, if you work in the IT field, try to write some utilities for yourself.
