Using enum as key for map

I want to use enum as keys and a object as value. Here is the sample code snippet:

public class DistributorAuditSection implements Comparable<DistributorAuditSection>{      

     private Map questionComponentsMap;  

     public Map getQuestionComponentsMap(){  
         return questionComponentsMap;  
     }  

     public void setQuestionComponentsMap(Integer key, Object questionComponents){  
         if((questionComponentsMap == null)  || (questionComponentsMap != null && questionComponentsMap.isEmpty())){ 
             this.questionComponentsMap = new HashMap<Integer,Object>();  
         }  
         this.questionComponentsMap.put(key,questionComponents);  
     }
}

It is now a normal hashmap with integer keys and and object as values. Now I want to change it to Enummap. So that I can use the enum keys. I also don't know how to retrieve the value using Enummap.
