Modern Java Book
https://www.reddit.com/r/programming/comments/1gnew38/modern_java_book/

This is a book intended to teach someone the Java language, from scratch. You will find that the content makes heavy use of recently released and, for the moment, preview features. This is intentional as much of the topic ordering doesn't work without at least Java 21. Right now I have several key areas where I could use some help: Writing Challenges. Most of the early sections have challenges students can do to test their understanding of the topics covered and for practice. I've shifted my focus away from these to make more progress on the main content of the book. Any assistance would be appreciated. Theming. A lot of the chapters are...bland. Purely technical. I find that when I have the imagination to "theme" the subjects they become higher quality and more engaging overall. See an anime you liked recently and think you can make the math chapters use the characters from it? Give it a shot! Fixing Mechanical Issues. I don't have an editor and I don't often proofread. If you find mechanical errors in my grammar or find issues with the way topics are ordered I would welcome fixes. Notably I do not want to open the floodgates for contributions on the main chapter content just yet. This has the downside of slower progress but the upside of a more coherent result. My primary goals with this are Get the ordering of topics right. By this I mean that every topic covered should have had its prerequisites covered in the topics previous. While "lesson 1: Inheritance" is clearly wrong in this regard, some things are more subtle. Be a template for other people. This is a book. Not everyone likes books, some like youtube videos, some like over priced udemy courses, some attend College, etc. Everyone has different learning paths. I hope this to be of use to anyone looking to make a more up to date Java curriculum and hope that the vague order of things (which I consider superior to the content produced with the Java of years' past) is carried through. Write as if the newest Java wasn't new. It's obvious when a book was written before Java 8 because it always has newer additions with "addendum: brand new stuff in Java 8." But the order language features were introduced is hardly a good order to teach them. You have to pretend that Java 23+ has always been the Java. Does it really make sense to show terrible C-style switch statements way before switch expressions? Write as if the words Object Oriented Programming, Functional Programming, etc. didn't exist. While I understand that these all have definitions and are useful concepts to know about, introducing them early seems to lead to either dogma, rejection of said dogma, or some mix thereof. None of them are actually needed to understand the mechanics of and motivation behind what we would call "object oriented" or "functional" techniques. They certainly don't work as justification for adding getters and setters to every class. My immediate short term goal is to get this "ready to go" for when anonymous main classes is in a stable Java release. Thats the point at which we could start to: Have actual students go through it without also needing to explain the --enable-preview mechanism. Use the topic order to build other sorts of non-book resources like videos, curriculums, projects, etc. Convince actual teachers to change from "objects first" to something less insane. I haven't integrated println or readln yet, but will do so eventually.  submitted by /u/bowbahdoe (https://www.reddit.com/user/bowbahdoe)
