You are compering 2 different types String accountNum and int accountNumber[0]. This is interesting, that you run it without troubles :)
As I understand, it must be like that:
f(accountNum2==bank.accountNumber[0])

In your BankAccount class create a getter that will return the bank account information.

public int[] getBankAccountInformation(){
    return accountNumber;
}

and then when it is returned, see if what the user inputted matches the data in the array.
