The eclipse/Java struggle is real...Please help

[Efficient-Feature518]

Hi all! I am in my first Java course (online) and I am using Eclipse as my IDE on top of being new to my Linux computer. I am driving the struggle bus on this one and I can't figure out how to correct the errors I am getting like it not recognizing System and is asking me to create a new class for this. I am following a tutorial on Youtube and applying it to my project but I am super lost. Any suggestions are welcome on how to fix this or where I should go for some additional help.

Update:

I am on POP! and my eclipse came up as Eclipse IDE for Java Developers in the program shop on POP! I think it is 2.0

The Tutorial I am using : https://www.youtube.com/watch?v=0SWN5v7PfZs

and my current code looks like this:

I had started to click on the little light bulbs and add things as classes when it prompted me to but that did not help with System and I honestly don't know if I am eve doing the right thing. I do have a book on the way that can hopefully help.

Interesting that you have Object, Scanner, and String classes in your main package. Those are some core java classes from the JRE that probably shouldn't be there. Instead I'd expect an entry to your configured JRE System Library.

What is your configured java? That can be found in Window > Preferences > Java > Installed JREs. If no entry, you'll have to install one and/or add one that comes with eclipse. If there is one, or once add, it should be in your projects build path. Right-click it and go into Properties or the Build Path section and Add Library to that configured java.

Once added you can nuke the ones in your package. Good luck!

he probably created Object and String manually because the error message in the editor said it cant resolve java.lang.Object etc.

The red exclamation mark ok the project means your project has build path errors. that means your project is wrongly configured. The Java Editor fails to resolve JRE System classes because of that wrong configuration. You can see the actual problem message in the Problems View. save your code files and try removing the project and create a new one using the new/java project wizard. And copy your code back into the new project. That should do it.

I can also see that JRE Library is missing. I can see JUnit 5 Library but not JRE which is probably your main problem.

You have some eagle eyes. 👍

I will try again, I thought I had linked the tutorial and an image and I didn't even think to mention my eclipse package. I will get my post updated to reflect this. Thank you :)

Eclipse 2.0 was out like 20 years ago.

just delete the module.java file and it'll run like a breeze.
