private String password;

public Customer(String userId, String password) {

}

2. Add three customers to the ArrayList in the Customer Data Access class with the following userIDs and passwords.

public class CustomerDataAccess {

private static ArrayList customers = new ArrayList();

static {

customers.add(new Customer("Cust1", "cust1"));

customers.add(new Customer("Cust2", "cust2"));

customers.add(new Customer("Cust3", "cust3"));

}

// methods to retrieve customers by userId or to add new customers

}
