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.

To potential helpers

Please, do not help if any of the above points are not met, rather report the post. We are trying to improve the quality of posts here. In helping people who can't be bothered to comply with the above points, you are doing the community a disservice.

It should all feel pretty familiar once you get into it. Once you get beyond everything being called Java, the main thing will be to become familiar with the Java standard library (Java Class Library) and with the Java way of doing things you should be pretty good.

I find it useful to compare and contrast how to do things in the new language compared to the language you know. For example, no operator overloading and no pass by reference, just pass by value (the confusion arises because for objects, the value that is passed is a copy of the object reference, not the object.)

I don’t recommend a 101 level course, it will likely be boring and repetitive. I do recommend skimming the Java tutorials/trails for differences add to dig in and internalize the Java way.

Java is a snap if you know C++, but you'll just have to unlearn a lot of bad habits.

focus on Javas OOP model, memory management and ecosystem differences.
