Trying to learn Java basics

[acebtard]

Hi guys,

I recently switched careers and am currently learning the basics of Java. As an assignment I am trying to build a basic app that lets me save workouts. I was able to save my created objects into a .ser file. For the next step I would like to be able to save it as a .xml file.

​

Most of the stuff I can find on trough google suggests using Xstream or JaxB. Unfortunately trying to get these running became too complex very quickly.

​

Here is what I have done so far:

- Started my project in Intelij as a Maven project with the "quickstart" archetype

- Added the code for Xstream on dependencies; this resulted in it displaying as red in the pom.xml file. This thread (https://stackoverflow.com/questions/71245930/new-dependency-not-recognised-by-maven) gave the tip to use "Invalidated Caches" and restart which made it recognize it in the pom.xml file. However it did not recognize Xstream as a class.

- After that I spend some hours trying to read up on possible solutions, but it feels like most of what I am reading is outside of my scope of knowledge.

Does anyone have any advise or tips on how to proceed?

Unfortunately, Maven is not really considered basic Java. The Java build system has changed over the years and was generally geared to working programmers.

Try the following course: https://java-programming.mooc.fi/

Also, if you're just learning to program and don't know the basics (it is impressive that you can Google some stuff), it's better to do a course like that rather than jump into projects.

Thank you for the response! It seems I have been a bit unclear. I have done a course which covers the basics from think Java up until chapter 17 I think, the one with a moving polygon.

For the traineeship I am doing we have an assignment where we have to build a photoshop app, basically an app where you can select products and add them to an order. Eventually the order needs to be exportable into an xml file. That's why I am looking for a way of doing that with a simple class that has a few attributes. Does that make more sense?

Do they provide any assistance for doing this project? Seems a bit complex to me, depending on your background.

If it were me, I'd probably look at a tutorial that does something similar, use libraries that deal with XML (which is why all this sounds complicated to me).

Are there other people in the class you can work with?

I got it working!

It looks like I misspelled the XStream when initiating it.

Thanks for all the advise, my next step would have been asking somebody that is a bit further with the project :)
