See if this helps,

  HashMap< String, String> map = new HashMap<>();
  Set keySet = map.keySet();
  Iterator iterator = keySet.iterator();
  while(iterator.hasNext())
  {
    //iterate over keys
  }

//or iterate over entryset 
Iterator> iterator2 = map.entrySet().iterator();

while(iterator2.hasNext())
{
    Entry next = iterator2.next();
    //get key
    next.getKey();
    //get value
    next.getValue();
}
