Problem implementing java.util.Iterable

[ozzyman]

import java.util.*;
import java.io.Serializable;

public class Customers implements Iterable<Customers.Customer>, Serializable {

    public class Customer {
        ...
        //constructor
        Customer(params) {
            ...
            addCustomer(this);
        }
    }

    private Set<Customer> customerSet = new HashSet<Customer>();

    public void addCustomer(Customer c) {
        customerSet.add(c);
    }

    public Iterator<Customer> getCustomers() {
        return customerSet.iterator();
    }

    public Iterator<Customer> iterator() {
        return getCustomers();
    }

    public Customer getCustomer(int cid) {
        for (Customer c:[COLOR="Red"][U]Customers[/U][/COLOR]) {
            if (c.id == cid) {
                return c;
            }
        }
    }
    
}

NetBeans is giving me the error for Customers (underlined in my code) that "cannot find symbol". Does anyone know what am I doing wrong here? I need to be able to iterate through all instances of Customer :confused:

Turns out this is the correct usage:

    public Customer getCustomer(int cid) {
        [COLOR="Red"]Customers myCustomers = new Customers();[/COLOR]
        Customer thisCustomer = new Customer();
        for (Customer c:[COLOR="red"]myCustomers[/COLOR]) {
            if (c.id == cid) {
                thisCustomer = c;
                break;
            }
        }
        return thisCustomer;
    }

Problem solved. Thanks for looking.

Makes me wonder though, will this mean it will iterate through ALL customers created or just the ones added to "myCustomers" variable?
