Are there any good Java courses that will teach you for free, besides StartAndroid?

Question

Java

Suggest a couple of projects. Because I want to know Java at a professional level! I need free courses because I unfortunately don’t have any money (. I’ll go through StartAndroid, but then, now I can’t understand anything there. JavaRush also tried it, but now from level 2 all tasks are only for a premium subscription, and it’s 50 dollars Tell me please, but only those who really teach for free.

Answer 1

Books. Free and efficient.

Answer 2

It's too early for you java
* Learn how to use google properly
* Learn how to use a torrent
* Learn English
Full of free books, ready-made answers to your questions, tasks, and so on. And if you can't find it on the very first links in Google - to program only from books or courses - you won't learn.

Answer 3

There is an excellent resource stepik.org, there is a lot of useful and free information, use it.
