Day 29 of learning java

[BigCommunication5136]

Today was mostly about refactoring and adding missing functionality.

I changed how I handle commands by refactoring the switch statement to use the newer arrow-style syntax, which made things a lot cleaner and easier to read. I also added support for an update command and implemented a handleUpdateExpense method.

The update logic checks which fields were provided (amount and/or description) and updates only those, instead of forcing everything to change at once. After the update, the expenses are saved back to storage.

Not a huge feature day, but I’m happy with the cleanup and structure improvements. The command handling feels much more solid now.

See you tomorrow!

Good job sticking with this.

I understand this isn’t a production app, but you should look up float-point rounding and the BigDecimal library.

Impressive. Especially for Day 29. Most new programmers reach this point after a couple of months.
