Im stuck with the code challenge, please help me. I write the code but the message show me "Try again" error.
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 ((csr = mSupportReps.poll()) != null) { csr.assist(customer); if (csr.getAssistedCustomers().contains(customer)) { mSupportReps.add(csr); } } playHoldMusic();
/********************************************
* TODO (1)
* Wait until there is an available rep in the queue.
* While there is not one available, playHoldMusic
* HINT: That while assignmentcheck loop syntax we used to
* read files seems pretty similar
********************************************
*/
/********************************************
* TODO (2)
* After we have assigned the rep, call the
* assist method and pass in the customer
********************************************
*/
/********************************************
* TODO (3)
* Since the customer support rep is done with
* assisting, put them back into the queue.

}
public void playHoldMusic() { System.out.println("Smooooooth Operator....."); }
}

40,533 PointsmSupportReps not being null means someone is available to assist, so you'll want to check for the opposite:
// While there are no support reps ready
while((csr = mSupportReps.poll()) == null) {
// Continue to play the hold music
playHoldMusic();
}
If the loop stops that means someone got selected, so we can use csr:
// Assist the customer
csr.assist(customer);
// Move back into the queue since they've finished assisting
mSupportReps.add(csr);
