I$\text{'}$m trying to output a certain number $(7000),$ but it keeps returning the same number I put in$.$ Am I missing something or did I not type something correctly? This is the code so far:

class UML$\_$Lab$\_$Driver $\{$

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

Person Bob $=$ new Person$("$Bob$")$;

Bob.deposit$(9000)$;

Bob.withdraw$(4000)$;

Bob.deposit$(2000)$;

System.out.println$($Bob$.$getAccountBalance$())$;$//$expecting $7000$

$\}$

$\}$

class Person$\{$

private Account account;

private String name;

private int value;

public Person$($String name$)\{$

this.name$=$name;

$\}$

public String getName$()\{$

return name;

$\}$

public void deposit$($int amt$)\{$

account $=$ new Account$($amt$)$;

$\}$

public void withdraw$($int amt$)\{$

account $=$ new Account$($amt$)$;

$\}$

public int getAccountBalance$()\{$

return value$=$account.getValue$()$;

$\}$

$\}$

class Account$\{$

private int value;

public Account$($int value$)\{$

this.value$=$value;

$\}$

public Account $($Account p$)\{$

value$=$p$.$value;

$\}$

public int withdraw$($int amt$)\{$

value $-=$ amt;

if$($value $<0)\{$

System.out.println$("$EXCESS WITHDRAW ALERT.

You will only withdraw the amount equal to what was left in your account."$)$;

value$=0$;

$\}$

return value;

$\}$

public int deposit$($int amt$)\{$

value $+=$ amt;

return value;

$\}$

public int getValue$()\{$

return value;

$\}$

$\}$
