Will the Java 2019 course and books be relevant in 2021?

Question

Java

I want to start learning Java using Schildt's book "Java. A Beginner's Guide" and the course "Java (Java) for Beginners: From Zero to Oracle Certification" on Udemy ( https://www.udemy.com/course/java-oca- oracle/ ). The only thing that confuses is that both the book and the course were released in 2019. How relevant will they be for an initial dive into Java? If there is something more recent, can you advise?

Answer 1

Good afternoon.
I would recommend reading G. Schildt's Complete Guide to Java instead of G. Schildt's "A Beginner's Guide to Java".

The only thing that confuses is that both the book and the course were released in 2019.

The year of issue is not so important. You can take the book at least 2009. It's important that the book you're reading was written about Java 8 or later, since many changes to the language (Java Stream API, etc.) have been made since that version.

How relevant will they be for an initial dive into Java?

For beginners, everything that can be read is relevant.

If there is something more recent, can you advise?

You can safely start with the books of G. Schildt. There is another tutorial for beginners - Java Head First. But for me there is too much water...
As for the courses on Udemy or youtube, coursera, etc. Of all the authors, I like Nail Alishev. I saw his courses on git & spring framework. He seems to have 2 java courses on udemy too. I can’t say anything objective about your course on Udemy, because I don’t know.
There are also foreign developers. For example, John Thompson, Tim Buchalka and others.

Answer 2

Java is fully backwards compatible, most of the knowledge from Java2 books is still relevant.

Answer 3

We need to look at something specific.
Sometimes books carry deep, unchanging and very important foundations and they can be read in N years.
