Bank Classs- logic for findAccount( )

Method findAccount( )

PUT message to user to enter account number

GET valid account number

FOR (i=0; i<numAccounts; i++)

IFaccounts[i].accNumber is NUM

RETURN i

ENDFOR

Class Bank . This class will contain the array of BankAccount objects (which are instantiated with either SavingAccount or ChequingAccount objects); You will need to keep two ints as well -a maxSize and numAccounts Methods o constructor )-allocates default size of 1000 o constructor (int) parameter is size of array to be allocated o addAccount:boolean success add or not; prompts user to enter data for an account which is added to arrayeither chequing or savings account is added if there is room displayAccount() - String prompts user to enter an account number to display, then returns data formatted to display or an error message should use toString() from BankAccount class This o printAccountDetails()- prints details of all accounts o updateAccount) prompts user to enter which account number to update, and by how much and then updates the balance appropriately returns success message or error message o findAccount) intprompts user to enter which account number they wish to find and re turns array index of where it is found otherwise returns -1 monthlyUpdate() process through each current account in the array and updates the balance appropriately
