Question ask about what kind of objects can be thrown using a throw statement? Throwable and Exception are obvious but RuntimeException is thrown by jvm not by user, isn't?


Thanks!

Not necessarily. You can throw any exception including RuntimeException using a throw statement.

A resposta correta seria: Throwable, Exception e RuntimeException?

Can you write it in English please?

The correct answer would be: Throwable, Exception and RuntimeException

Exception and Error are two main subclasses of Throwable.

What are the other subclasses?

There are several but not direct. Updated the explanation to make it clearer.

thank you for your feedback!

You can only throw a Throwable using a throws clause

Is this true? It seems that I can throw new Throwable(), just like with any other exception.

Yes, it is correct. You quoted only half of the sentence. The complete sentence written in the explanation is:

You can only throw a java.lang.Throwable object (i.e. an instance of Throwable or any of its direct or indirect subclasses) using a throws clause.

Please check the part written within the parentheses. That should make it clear.

Thanks!
From the explanation, I got the impression, that

you can only throw a Throwable object using a THROWS clause,

but I should've read It

is you can only throw a THROWABLE object using a throws clause
