Why should you catch a checked exception late in a catch {} block?

You should not try to catch the exception before your program can handle it in an appropriate manner. The natural tendency when a compiler complains about a checked exception is to catch it so that the compiler stops reporting errors.
It is a bad practice to sweep the exceptions under the carpet by catching it and not doing anything with it.
The best practice is to catch the exception at the appropriate layer (e.g. an exception thrown at an integration layer can be caught at a presentation layer in a catch {} block), where your program can either meaningfully recover from the exception and continue to execute or log the exception only once in detail, so that user can identify the cause of the exception.
