If we add duplicate items in a hashmap as in MyHashMap.put("Shree",7000); MyHashMap.put("Shree",9000); when i ask to print out the contents using an iterator, i see that only the last stored value is valid. That is, I get Shree 9000 What exactly happens out there? Is the first reference removed and the new one added?
