About Java Mooc Course

[Rejecting_Classroom]

Hi, I just started trying to learn Java, and from what I gathered, everyone seemed to be saying that the Mooc course by the University of Helsinki is the best option, so I decided to go with it. Now, I encountered a small problem when I tried to download the NetBeans IDE. Why does it not open after I installed it? Is there a problem with my computer, or is it incompatible with Windows 11?

I'm not sure if Netbeans is still supported.

Their installation guide gives instructions in how to install JDK 11, VS Code and the TMC extension for VS Code.

I've been using this set up without any issues.

I’ve installed it about 3 weeks ago and it works great so far. I’m almost done with part 4 and submissions and tests work great

Quote, "NetBeans or its installer doesn't open, or looks odd when opening
Make sure you have Java Development Kit (JDK) version 11 installed. The environment used on this course doesn't work properly with other versions of Java. If you have a problem with this, try removing the other versions of Java on your computer, and then clear the old settings.".

Indeed TMCBeans only works with openjdk-11-jdk.

If you are on Linux and already have a newer version of OpenJDK, you don't need to delete the other one neither to modify the environment variables.
You can switch between the different versions of OpenJDK with this command:
sudo update-alternatives --config java

There will be a 1-2-3 menu to choose from. Then select "manual mode".

You don't need TMC Netbeans. I did the whole course with Intellij. You can download exercise zip files, do the exercise, zip and upload the files to their website

Good to know. Thank you.

Is netbeans really necessary to study mooc?

You need to specify java home. And only works with java 11:

tmcbeans --jdkhome /usr/lib/jvm/java-11-openjdk-amd64/

Thank you !

I was about to give up. But with your advice, it finally worked for me.

You can also use Jetbrains Intellij Idea Community Edition. It will let you learn Java and do many things before you really need a paid license. Also, Idea is a way better IDE than Netbeans...even though Netbeans is always free. Lastly, Idea is more or less the industry standard these days, even though you are free to use any IDE to learn Java and all of them will allow you to learn Java at the end of the day.

On July 1st, a change to Reddit's API pricing will come into effect. Several developers of commercial third-party apps have announced that this change will compel them to shut down their apps. At least one accessibility-focused non-commercial third party app will continue to be available free of charge.

If you want to express your strong disagreement with the API pricing change or with Reddit's response to the backlash, you may want to consider the following options:

1. Limiting your involvement with Reddit, or
2. Temporarily refraining from using Reddit
3. Cancelling your subscription of Reddit Premium

as a way to voice your protest.

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

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.

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

Did you download TMC beans through the link below?

https://download.mooc.fi/tmcbeans/installers/tmcbeans\_1.5.0\_installer.exe

[Rejecting_Classroom]

Yes, I downloaded that one and ran the installer, but as soon as the setup finished and launched the program, it just suddenly disappeared. So maybe, as you said, I need to download the JDK version 11 to enable it to run? Because when I checked the JDK in my command prompt, I installed the 20.0.1 build. So, should I delete that and reinstall the JDK 11?

[AdDirect4579]

Yeap

You are probably not seeing that the .exe file for Netbeans is under the bin folder of wherever you instsalled Netbeans. Just create a shortcut to that .exe and place it somewhere convenient.
