18,813 PointsPart 3: Add CustomerSupportRep back to queue not working
My code seems to do what's asked, but doesn't work. No compile errors - just "Bummer! Try again."
Here's the code including the directions for this part:
import java.util.ArrayDeque;
import java.util.Queue;
public class CallCenter {
Queue<CustomerSupportRep> mSupportReps;
public CallCenter(Queue<CustomerSupportRep> queue) {
mSupportReps = queue;
}
public void acceptCustomer(Customer customer) {
CustomerSupportRep csr;
while (mSupportReps.size() == 0) {
playHoldMusic();
}
csr = mSupportReps.poll();
csr.assist(customer);
/********************************************
* TODO (3)
* Since the customer support rep is done with
* assisting, put them back into the queue.
********************************************
*/
mSupportReps.add(csr);
}
public void playHoldMusic() {
System.out.println("Smooooooth Operator.....");
}
}
import java.util.List;
import java.util.ArrayList;
public class CustomerSupportRep {
private String mName;
private List<Customer> mAssistedCustomers;
public CustomerSupportRep(String name) {
mName = name;
mAssistedCustomers = new ArrayList<Customer>();
}
public void assist(Customer customer) {
System.out.printf("Hello %s, my name is %s, how can I assist you.%n",
customer.getName(),
mName);
System.out.println("...");
System.out.println("Is there anything else I can help you with?");
mAssistedCustomers.add(customer);
}
public List<Customer> getAssistedCustomers() {
return mAssistedCustomers;
}
}
public class Customer {
private String mName;
public Customer(String name) {
mName = name;
}
public String getName() {
return mName;
}
}

It looks like the test script for the challenge doesn't (or didn't at one point) accept all correct ways of doing this. Just change your while loop code to match a successful example from that discussion.
(Yes, I answered my own question...)
