Consider the following UML and the corresponding suggested implementation.

Find all the coupling between classes; make sure to identify the type of the

coupling.

Redesign the model in order to decrease the coupling as much as possible.

public create $($string id$,$ int $x)$

$\{$

account ac$=$new account$($id$)$;

db$.$add $($ac$,$ x$)$;

$\}$

public add $($account $c,$ int $x)$

$\{$

if $(x==0)$

$//$ get account id and insert it into student table.

if $(x==1)$

$\}$

$//$ get account id and insert in into admin table.
