How do I return a value in a HashSet?

I need to write a method for this:

** returns the customer with the specified id, or null if the

* customer is not registered at the branch

* @param id the customer's number

* @return the customer is registered with the branch,or null

**/

allCustomers is the HashSet of customers. So I need to return the customer in the HashSet that has the id specified in the parameter....

Its not something I want! Its a question on my University coursework. But yeah it sounds like HashMap would have done a better job, don't know why they chose HashSet.

Would this work:

public Customer getCustomer(int cNo)

{

for(Customer c: allCustomers){

if(c.getCustomerNo()==cNo){

return c;

}

}

return null;

}
