Books on java server side. What to read?

Question

Java

What can I read (see) to understand the basics of the Java back-end? If it matters, then I write mainly for android.
There is practically no knowledge in this area, I would like to get at least a basic understanding of this. Thanks

Answer 1

Spring In Action is good for the comprehensive study of Spring.
I advise you to watch Evgeny Borisov's lectures "Spring Builder" and "Spring Ripper" + his other lectures on Spring on the JUG channel
To learn Java Zen, you can study "On Java 8" by Eckels.
Good luck with learning!

Answer 2

Spring and its ecosystem. The vast majority are written using this framework. You can read this Spring 5 Rob Harrop
