$9.$ Consider the following method.

$\{$

$$ int j $=1/$ k;

Part A$.$

Assume that variable x is an array of int that has been initialized to be of length $3.$ For each of the following calls to method f$,$ say what $($if anything$)$ is printed by f$,$ and what, if any, uncaught exceptions are thrown by f$.$

$$

$$

A$.$f$(0,$ x$,"$hi$")$; $$

prints:

$$

$$

throws:

$$

$$

B$.$f$(10,$ x$,"")$;

prints:

$$

$$

$$

$$

throws:

$$

$$

C$.$f$(10,$ x$,$ "bye"$)$;

prints:

$$

$$

$$

$$

$$

throws:

$$

$$

D$.$ f$(10,$ x$,$ null$)$;

prints:

$$

$$

$$

$$

throws:

$$

$$

Part B$.$

Why doesn't f need to have a throws clause?
