Answer / brijendra kumar (xavient)
Actually in HashSet we are able to add the duplicate value,
but at the execution time JVM ignore the duplicate value.
HashSet<String> T= new HashSet<String>();
T.add("k");
T.add("k");
System.out.println("size" +T.size());
when we execute these line of code then we got the size of
HashSet is 1.
Due to this reason we are unable to iterate the duplicate
value from HashSet.
