The (1), (4), (5) and (6) are the only four that can be thrown. An Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch. The Throwable class is the superclass of all errors and exceptions in the Java language. The class Exception and its subclasses are a form of Throwable that indicates conditions that a reasonable application might want to catch (checked exceptions) RuntimeException is the superclass of those exceptions that can be thrown during the normal operation of the Java Virtual Machine.
