This program is going to maintain a list of customers’ names and bank account balances. 1. Create a class called CustomerList with a main method that instantiates an ArrayList of String objects called customerName. Invoke the add method to add the following names into the ArrayList: Cathy Ben Jorge Wanda Freddie 1. Print each name in the ArrayList using a for a loop. 2. Create another ArrayList object called customerBalance, to save users’ balance. What is the type of this ArrayList? double or Double? You just need to declare this ArrayList and leave it empty for now. 3. For each customer, print the name and ask the user to enter the initial balance for this customer. Save the initial balance into ArrayList customerBalance. Use a loop to get this done for all 5 customers. The program should print out this for the first customer: Example: Please enter the account balance for Cathy: (waiting for user’s input …) Code: for(int i=0; i<5;i++) { Print(“Please enter the account balance for ”+customerName.get(i)); customerBalance.add(scan.nextDouble()); } 4. Print the balance for each customer to validate that you did right in the step above.
