does `try-catch` actually throw the exception before catching it?

The code inside the `try` block throws an exception, and then the `catch` block is executed with the thrown exception

well, at least the code in the `try`  block is supposed to be capable of throwing the particular exception that the `catch` block takes care of, but since unchecked exceptions doesn't have to be declared (and all exceptions in Kotlin are unchecked), I can be hard to figure out where a particular exception can be thrown. And it's also possible that after a refactoring or code change, a particular exception isn't thrown any more, but due to an overside of the dev who did the code change, the catch-block wasn't updated as well.
The compiler won't complain about unneccessary catch-blocks, but IDEs should mark unused exceptions (at least IntelliJ does).
