This was helpful. Thank you, Sir.
Just to summarise:

If you want to create a Checked Exception i.e. an exception that must be handled or reported, without it you can’t even compile the program.
Then one should extend their custom Exception class from Java's *Exception* class.
Otherwise, if you want to create an Unchecked Exceptions i.e. you don't care whether the user of the class reports or doesn’t handle it.
Then in that case extend your custom Exception class from Java's *RuntimeException* class.
