Yeah because exception1 and exception2 are both checked exceptions and when you are catching a checked exception, there should be a statement in the try block which throws or declares that it throws that checked exception. I guess the explanation given by examlab is pretty much clears that point.

I think the error message is pretty self explainatory:

Exception in thread "main" java.lang.Error: Unresolved compilation problem:
Unreachable catch block for exception1. This exception is never thrown from the try statement body
