Hi! Like most people starting out with coding, I've made a code of a finance-app in one single file. Now, I'm trying to devide my code in MyAccount.java to a second class CSVHandler.java, but I am encountering some errors. How can I best face this, and do you have any tips when you're at that stage where you have ~360 lines of code and want to divide it into maybe some classes? I really appreciate the help and if it would be easier to go over it together in a vc I would be down for that too! Thank you!

You'll get more people looking at it if you just drop the java sourcefile(s) here instead of a zip. The bot will upload it as a 'gist'.

If you drop the file here it'll get uploaded. You won't be able to paste it into a post.
@dense forum what problems are you having. You mentioned errors - what kind of errors?
I expect you might want to break it into
Transaction- a data-model class that represents a single transaction (instead of aLinkedHashMap)Account- a data-model class that allows deposits and withdrawals and answers questions about the balance and the history of transactions (this could still use aLinkedHashMap<String, Transaction>. This could have asaveToCsv(Path)and a factory method to yield an account from a CSV.PersonalFinance- The commandline UI of the application, holding a currently loaded account and having the application entry point (the main method).

model-view-controller
a way to organize ur code
splitting data/model, the view/display/ui and the logic/controller from each other
a technique that allows u to creates flexible and modular code
where u also can easily swap out parts against others
for example introduce a new ui system without having to touch most of the code
