The following code would be good to: Iterator iter $=$ m$.$iterator$()$;while $($iter$.$hasNext$())\{$String name $=$ iter.next$()$;$\}$A$.$ iterate through a map m one element at a timeB. iterate through a String m one letter at a timeC. iterate through a set m one element at a timeD. iterate through a map m in the order elements were added E$.$ all of the above
