Can exceptions be caught?
Mistake 2: Catch unspecific exceptions Exception in the main method of your Java SE application. But keep in mind that the first catch block that handles the exception class or one of its superclasses will catch it. So, make sure to catch the most specific class first.
What happens when an exception is thrown and never caught?
What happens if an exception is not caught? If an exception is not caught (with a catch block), the runtime system will abort the program (i.e. crash) and an exception message will print to the console.

Which is an example of catching multiple exceptions?
1. Catching multiple exceptions There are as many catch blocks as the number of exceptions which can be thrown from the code safeguarded by the try block. Here’s an example:
How to catch Unknown Exception and print it?
