Java checked and unchecked exceptions

Question

1. If I create an exception class that extends Exception, will my class be checked or unchecked? I note that the subclass of Exception called RuntimeException is an unchecked exception whereas all other subclasses of 'Exception' are checked exceptions.

2. If I create an exception class that extends RuntimeException, can I specify that this class is checked?

Answer 1

1) Checked

2) No

If you extend Exception -> checked

If you extend RuntimeException -> unchecked

From documentation:

The class {@code Exception} and any subclasses that are not also * subclasses of {@link RuntimeException} are checked * exceptions
