Throwing exceptions and changing name to a default name

[geforce]

Okay lets say I have a method called setName() and it needs to follow the regex and it cant be empty, if that statement is false, it throws an exception. Once it's false and throws it's exception I want it to turn into a default name for example like "unknown name" but whenever I do and run it only the error exception pops out, would I need to do something in the setName() part or getName() part? I tryed the getName() already and setName(), don't know what I'm doing wrong.

Can You show what You tryed?

You can have method called getName(), but not class, since getName() is not valid class definition.
But if You say class getName{}, than it could be class.

It's a method, typo.

Please explain: what do you mean by "follow the regex"?

... and it cant be empty,...

Please explain: what can't be empty? The parameter passed? Something returned from the method?

... if that statement is false, it throws an exception.

Please explain: what statement? What do you mean by "is false"?

... Once it's false and throws it's exception I want it to turn into a default name for example like "unknown name"

Please explain: turn what into a default name?

... but whenever I do and run it only the error exception pops out, would I need to do something in the setName() part or getName() part? I tryed the getName() already and setName(), don't know what I'm doing wrong.
