Java checked and unchecked exceptions

Question

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

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

Exceptions are checked unless they inherit from RuntimeException or Error

If your class extends Exception it can throw checked exceptions.

If your class extends Error or RuntimeException it can throw unchecked exceptions.

If you create class that extends Exception it would be checked. You can't specify RuntimeException as checked since it is unchecked exception
