5,114 PointsCall Center Challenge! It keeps asking me to call the assist() method even though I already have.
I am on the Call Center Challenge and I am having trouble finding out what I did wrong. The preview looks good, however there is an error on the top of the screen that Says "Bummer! did you remember to call the assist method?". I did call the assist method so I am not sure what is wrong. Any help is greatly appreciated.
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 = new CustomerSupportRep("csr");
customer = new Customer("customer");

23,733 PointsHi Shane! You shouldn't create a new CustomerSupportRep. You just need to get one from the queue. Also, the customer is passed into the method so no need to create one:
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;
/********************************************
* 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
********************************************
*/
while(mSupportReps.size() == 0){
playHoldMusic();
}
/********************************************
* TODO (2)
* After we have assigned the rep, call the
* assist method and pass in the customer
********************************************
*/
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.....");
}
}

5,114 PointsI completely missed that. The part about poll one out of the customer support queue. Thank you for the help again.
