    Default Loop to deposit money into bank account array

    Ask the user how much they would like to deposit into the first account and how much would they like to deposit into the second account. Update the accounts accordingly.

    You must use a loop here to process the deposit for each account in the array.

    How do i create a for loop that loops through the array and deposits into each account?

    public class BankAccountTesting {
     
        public static void main(String[] args) {
     
            BankAccount[] account = new BankAccount[2];
            account[0] = new BankAccount("12345","John Brown");
            account[1] = new BankAccount("6789","Paul brown");
     
            printAccounts(account);
     
            System.out.println("How much to deposit to Account 1 ?");
            double deposit1 = EasyScanner.nextDouble();
     
            System.out.println("How much to deposit to Account 2 ?");
            double deposit2 = EasyScanner.nextDouble();
     
     
            for(int i = 0 ; i < account.length ; i++){
     
                account[i].deposit();
     
     
            }
     
     
            printAccounts(account);
     
        }
     
        public static void printAccounts(BankAccount [] account){
            for (int i = 0 ; i<2 ; i++){
                System.out.println("Bank Account Details" + (i+1));
                System.out.println("Account Name : " + account[i].getAccountName());
                System.out.println("Account Number : " + account[i].getAccountNumber());        
                System.out.println("Balance : " + account[i].getBalance());
                System.out.println(" ");}       
        }
     
    }

    begin loop
    get the next account object from the array
    do the processing for that account
    end loop

    The do the processing step needs to be expanded into all the steps needed to process the account.
    such as asking the owner some questions, getting his response and calling methods in the account object to update it

    Thanks. Should it take and store the variables then run the loop?

    System.out.println("How much to deposit to Account 1 ?");
            double deposit1 = EasyScanner.nextDouble();
     
            System.out.println("How much to deposit to Account 2 ?");
            double deposit2 = EasyScanner.nextDouble();
     
     
            for(int i = 0 ; i < 2 ; i++){
     
                account[i].deposit(Not sure what goes here);
     
     
            }

    Everything should be done when looking at the account object inside the loop.

    Bit i cant figure out is how to move to the next deposit? Switch between deposit0 and deposit1 variables. Cant figure out the use of i.


            for(int i = 0 ; i < 2 ; i++){
     
            System.out.println("How much to deposit to Account " + (i + 1) + " ?");
     
            double deposit0 ;
            double deposit1 ;
     
            deposit[i]= EasyScanner.nextDouble();
     
            account[i].deposit(deposit[i]); }

    There should only be one deposit amount for the current account that is being processed. What if the array had 100s of accounts in it?

    Is this looking like its heading in the right direction?

     
            for(int i = 0 ; i < 2 ; i++){
     
            System.out.println("How much to deposit to Account " + (i + 1) + " ?");
     
            double deposit ;
            deposit = EasyScanner.nextDouble();
     
            account[i].deposit(deposit); 
             }
