Here is what's right.

The the root of the exception class hierarchy is class java.lang.Throwable. This class has two subclasses: java.lang.Error and java.lang.Exception.

A throw statement can throw any object o where o instanceof Throwable.

A catch clause can catch any object o where o instanceof Throwable.

The throws clause in a method signature can include any type that is Throwable or a subtype of Throwable.
