I$\text{'}$m trying to output a certain result, but it keeps returning an unexpected thing. I know I$\text{'}$m missing something, but I don't know what it is$.$ This is the code so far:

class UML$\_$Lab$\_$Driver $\{//$le conductor

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

Bank Bob $=$ new Bank$()$;

Bob.addPerson$("$Bob$")$;

Bob.depositAccount$("$Bob$",40000)$;

Bob.withdrawAccount$("$Bob$",25000)$;

Bob.getAccountBalance$("$Bob$")$;$//$expecting $15000$

$\}$

$\}$

class Bank$\{$

private Person$[]$ persons $=$ new Person$[10]$;

private static int personCount;

public void addPerson$($String name$)\{$

Person person $=$ new Person$($name$)$;

persons$[$personCount$]=$ person;

personCount$++$;

System.out.println$($persons$[0])$;

$\}$

public void removePerson$($String name$)\{$

boolean found $=$ false;
