Trouble inputting to an Array...

Question

I have the following setup:
CLASS STORAGEBUSINESS
private ArrayList<Customer> storageCustomer;
// setters & getters
public void setCustomers() {
  if (storageCustomer == null)
     storageCustomer = new ArrayList<Customer>();
public ArrayList getCustomer() {
  return storageCustomer;
// This method adds a customer ...
public boolean addCustomer(Object inCustomer)
  if (inCustomer instanceof Customer)
       return getCustomer().add(inCustomer);
  else
     return false;
}CLASS INTERFACE
public void createACustomer()
  if (storageBusiness != null)
    Customer customer
     = new Customer(
                Console.readInt  ("Customer ID created: "),
                Console.readLine ("Please enter name:  "),
          Console.readLine ("Please enter address: "),
          Console.readInt  ("Please enter contact phone number: "));
                System.out.println(customer);
    if (storageBusiness.addCustomer(customer))
     System.out.println("\n Customer was added successfully");
    else
     System.out.println("\n Customer was -NOT- added");
  else
         System.out.println("Function did not perform");
}But for some reason I am not able to input into Array storageCustomer, can anyone help.

Answer 1

Do you mean that,
private ArrayList<Customer> storageCustomer;
public void setCustomers() {
  if (storageCustomer == null)
     storageCustomer = new ArrayList<Customer>();doesn't actually create an array (or array list). I must be way off here. What do I need to create an array? One that is created from Class Customer.
