Question $1$: What is the output of the

following?

class Changelt

$\{$

static void dolt$($ int$[]$ z $)$

$\{$

z $=$ null ;

$\}$

$\}$

class Testlt

$\{$

public static void main $($ String$[]$ args $)$

$\{$

int$]$ myArray $=\{1,2,3,4,5\}$;

Changelt.dolt$($ myArray $)$;

for $($int $j=0$;$j$ myArray.length; $j++)$

System.out.print$($ myArray$[$j$]+"")$ ;

$\}$

$\}$

$12345$

Nothing will be printed.

The program will halt with a run time error.

$000000$
