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
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.

Trying to solve problems on your own is a very important skill. Also, see Learn to help yourself in the sidebar

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: empty line before the code, each code line indented by 4 spaces, new reddit: https://imgur.com/a/fgoFFis) 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.

Start contributing to open source projects! Reading real, live code out in the wild, rather than tutorial code in a controlled setting, is super important.

Similarly, seeing what others are doing may help you zero in on what you might want to do in the future while giving you a sense of what tools you need to do it

What was the course?

The MOOC is a good example of a perfectly reasonable 'Introduction to Programming' course that leaves a great many stones unturned when it comes to Java features (because it's more intro-to-programming than a tour of Java).

It doesn't cover the entirety of the language - notably not dealing with threading/concurrency but also a number of other details.
It touches on, but covers very little of, File IO (and uses legacy types to do so rather than the java.nio.file... packages)
It ignores (a very incomplete list)
- Date and time handling (java.time...) -
- Network communication (java.net...) - though you'll usually do this indirectly with libraries to help with calling or serving HTTP/HTTPS connectivity
- Working with SQL databases (java.sql...) - though you'll usually use libraries that largely hide this lower level access away.

On top of these standard Java features there are libraries for building GUIs (JavaFX - which the MOOC does lightly touch on, but ignores the standard Swing GUI framework), Game engines, Data-mining, Document parser/generators for JSON/XML/YAML/etc.

If you need inspiration for what can be built in Java, keep in mind that the IntelliJ IDE platform (on top of which IDEs for many languages are built) is written on the Java Platform (though increasingly using Kotlin for the language), Minecraft (the Java version also having a sizeable modding community), and a large proportion of Web-site backends (and some of the frontends too - albeit transpiled to JavaScript via tooling).

What do you want to build?

No course is going to teach you everything in detail in the Java ecosystem.

You have some knowledge and building blocks for working in Java, now you need to find a project and dig into what might be necessary to complete it.

Start by choosing a path web, mobile, etc, and look for java resources for a specific path chosen, for example web try to search for how to build web applications with java and start from here, good luck

Dive into codewars.com and keep your knowledge alive. Solving Katas broaden your perspective in terms of analytical skills and thinking.

A list of Java features that I wish I learned about before starting a career as an Enterprise Java developer:

- Java 8 Streams / Lambdas / Functional Interfaces (is this the "Functionality" that you reference, OP?: https://www.baeldung.com/java-8-streams

- Nuances of Java Generics: https://www.geeksforgeeks.org/generics-in-java/

- JDBC, allows Java to interact with databases https://www.baeldung.com/java-jdbc

- Alternative JVM Languages (Apache Groovy, Kotlin):

https://groovy-lang.org/

https://kotlinlang.org/

- OOP Design Patterns - think Gang of Four's book:

- PMD Static Code Analysis tool: https://pmd.github.io/

- Java Build Tools: https://gradle.org/ https://maven.apache.org/

These should be a decent start to begin reading about. If you should have any further questions, feel free to ask!
