Given the following code fragment $($assume no compiling error$)$:

Student student $=$ null;

try $\{$

System.out.println$($student$)$;

System.out.println$($student$.$getName$())$;

$\}$ catch $($Exception e$)\{$

System.out.println$($null$)$;

$\}$ finally $\{$

System.out.println$($null$)$;

$\}$

How many times will null be printed when this code fragment is executed?
