)Which of following can be thrown using the throwstatement?
Amanda [17]

Answer:

All of Given

Explanation:

The throw keywords can be used to throw any Throwable object. The syntax is :

throw <Throwable instance>

Note that Error and Exception are subclasses of Throwable while RuntimeException is a subclass of Exception. So the hierarchy is as follows:

Throwable

-- Error

-- Exception

   -- RuntimeException

And all of these are valid throwable entities. As a result "All of Given" is the most appropriate option for this question.
