Is it ok to throw actions in Spring boot web app?

Question

Java

I know that the program slows down during the try {} catch, but I already wrote it and there is no time to redo it.
The logic of the program is as follows:
If the user wants to place an order and he has no money -> the InsufficientFunds exception is thrown and caught in the controller -> it is logged and sent to the front.

To what extent is this a gross error and is it a mistake at all?

Answer 1

Fine.
