Design the classes and data structures for this problem:

• Imagine you have a call center with three levels of employees: respondent, manager and director.
• An incoming telephone call must be first allocated to a respondent who is free. If the respondent can't handle the call, he or she must escalate the call to a manager If the manager is not free or not able to handle it, then the call should be escalated to a director
• Design the classes and data structures for this problem. Implement a method dispatchCalLO which assigns a call to the first available employee

//route the calls to the correct person
public class CallHandler{
   //Singlethon
   private static CallHandler instance;

   //3 levels of employees
   private final int LEVELS = 3;

   //initialize number of each level
   private final int NUM_RESPONDENTS = 10;
   private final int NUM_MANAGERS = 4; 
   private final int NUM_DIRECTORS = 2;

   //list of emplyees by level
   ArrayList<ArrayList<Employee>> employeeLevels = new ArrayList<ArrayList<Employee>>();

   //queues for each call's rank
   ArrayList<ArrayList<Call>> callQueues;

}

//represents a call from a user. it has a minimum rank and is assigned to the first emplyee who can handle it
public class Call{
   //minimal rank of employee who can handle the call
   private Rank rank;

   //person who is calling
   private Caller caller;

   //employee who is handling call
   private Employee handler;

   public Call(Caller c){
   	rank = Rank.Responder;
   	caller = c;
   }

   public void setHandler(Employee e){
   	handler = e;
   }

   public void reply(String message){

   }

   public Rank getRank(){
   	return rank;
   }

}

abstract class Employee{
   private Call currentCall = null;
   protected Rank rank;

   public Employee(){

   }
   
}
