Suppose that the T is a reference to a container object that has a cursor and that T implements the Cursor interface from Topic $4,$ exercise $1.$ Which of the following code fragments would correctly perform iteration over all elements in T$,$ assuming that T is non$-$empty? $($check all that apply$)$

$//$ Fragment A

T$.$goFirst$()$

while$($T$.$itemExists$())\{$

$//$ Do something with T$.$item$()$

T$.$goForth$()$

$\}$

$//$ Fragment B

T$.$goFirst$()$

while$(!$T$.$after$())\{$

$//$ Do something with T$.$item$()$

T$.$goForth$()$

$\}$

$//$ Fragment C

T$.$goFirst$()$

while$($T$.$item$()!=$ null$)\{$

$//$ Do something with T$.$item$()$

T$.$goForth$()$

$\}$

$//$ Fragment D

while$(!$T$.$before$()$ && $!$T$.$after$())\{$

$//$ Do something with T$.$item$()$

T$.$goForth$()$

$\}$
