Question

This needs to be in Java:

Bank Class- addAccount()

Bank Class data members:

-->private BankAccount[ ] accounts;

-->private int numAccounts = 0;

--> private int sizeBank =100;

Method addAccount( ):

IF numAccount >= sizeBank

PUT error message- no room

RETURN

PUT message to user to enter type of account - c or s (where c = chequing and s = savings)

GET type

IF accType == 's'

account[numAccounts] = new SavingsAccount( );

ELSE accounts[numAccounts] = new ChequingAccount( );

IF(accounts[numAcccounts].addBankAccount())

//account added successfully

numAccounts++

ELSE PUT account not added

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
