Hi sir, this is the answer with some comments:

import java.util.ArrayDeque;
import java.util.Queue;


///this was my take
public class CallCenter {
  Queue<CustomerSupportRep> mSupportReps;

  public CallCenter(Queue<CustomerSupportRep> queue) {
    mSupportReps = queue;
  }

 /*task 1 = First i did a while loop and checked if there there is any "representative" in the queue by checking the queue size, if its 0 there
  is none and i call the playHoldMusic.
*/
  public void acceptCustomer(Customer customer) {
     CustomerSupportRep csr;
    while(mSupportReps.size() == 0)
    {
      playHoldMusic();
    }

  /* task 2 = then we need to get an available representative from the queue and we do this by assigning csr(which is of type CustomerSupportRep) to the result of the poll method which remove a representative out of the queue and retrieves an avilable one which stored in csr.
then i use the assist() method and pass customer. 
*/  

    csr = mSupportReps.poll();
    csr.assist(customer);

   //task 3 = i put the csr which is a  "representative" back to the queue
   mSupportReps.add(csr);
  }

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

}

hope that helps.
