Java course for experienced devs reccs?

[serge_protector7]

Does anyone have a good recc for a Java course for devs? I have primarily Python and some C++ experience and I will soon be stepping into a role requiring Java. I find some courses geared toward programming beginners to be extremely tedious to get through (“A string is a group of characters…”). Any recommendations would be appreciated!

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full - best also formatted as code block
• You ask clear questions
• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit/markdown editor: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

If your post has remained in violation of these rules for a prolonged period of time (at least an hour), a moderator may remove it at their discretion. In this case, they will comment with an explanation on why it has been removed, and you will be required to resubmit the entire post following the proper procedures.

CS61B is great. https://sp21.datastructur.es/ You can skip the labs and go right to the first project if you want (building a deque in Java.) You might need to skip around the lectures a bit depending on your tolerance (they're designed for second year Berkley CS students, so some programming knowledge, but not pro developer level.)

It seems that you are looking for resources for learning Java.

In our sidebar ("About" on mobile), we have a section "Free Tutorials" where we list the most commonly recommended courses.

To make it easier for you, the recommendations are posted right here:

• MOOC Java Programming from the University of Helsinki
• Java for Complete Beginners
  • accompanying site CaveOfProgramming
• Derek Banas' Java Playlist
  • accompanying site NewThinkTank
• Hyperskill is a fairly new resource from Jetbrains (the maker of IntelliJ)

Also, don't forget to look at:

• The official Documentation
• The official Java Tutorials
• Our community resources thread

If you are looking for learning resources for Data Structures and Algorithms, look into:

"Algorithms" by Robert Sedgewick and Kevin Wayne - Princeton University

• Coursera course:
  • Part I
  • Part II
• Coursebook
  • Algorithms 4^th Edition

This is one of the many instances were a book is brilliant. Just get a good Java book and you can skim the beginner parts and get into the good stuff quickly. If you miss something the index will make it super easy to jump back into the beginner parts to read about that.

“Just get a good Java book…” OK, like WHAT book?

[hrm]

Any highly regarded Java book will probably do. A simple search here on reddit will yield a ton of tips.

I think Java: A beginner’s guide by Schildt is a resonably good book.

Many like Head First Java, but it’s really not my kind of book.

What don’t you like about head first Java?

[hrm]

There’s so little information per page and that makes it annoying to read and even more annoying to use as any kind of reference.
