How do you iterate through a HashMap with the iterator object

Answer 1

Create entrySet() then create iterator for it.
HashMap hm = new HashMap() ;
Iterator it = hm.entrySet().iterator();

Now it.next() returns a mapEntry() which have key, value pair.
MapEntry<> e = it.next() ;
e.getKey() returns key
m.getValue() returns value...
