Problem in printing elements of a Set element

Question

I am using iterator to print the elements of a set as below:
Set<String> set = new HashSet<String>();
set.add("element");
Iterator it = set.iterator();
while (it.hasNext()) {
                 System.out.println(it.next() + "\n");
}The above code perfectly prints all the elements in the set.
I am facing problem when I am trying to store the value of set element in a string and print as below:
while (it.hasNext()) {
                 System.out.println(it.next() + "\n");
                 String e = (String)it.next();
System.out.println(e);
}All the elements in the set are not printed. Why is it behaving like so?

Answer 1

while (it.hasNext()) {
                 System.out.println(it.next() + "\n");
                 String e = (String)it.next();
System.out.println(e);
}You are calling it.next() method twice so it is printing alternate values.
try this:-
while (it.hasNext()) {
                 String e = (String)it.next();
                 System.out.println(e + "\n");
System.out.println(e);
}
