how does one explain this syntax?

This passes for a demonstration and teaching example for a TreeMap


import java.util.TreeMap;
import java.util.Set;
import java.util.Iterator;
import java.util.Map;

public class Details {

   public static void main(String args[]) {

      /* This is how to declare TreeMap */
      TreeMap<Integer, String> tmap =
             new TreeMap<Integer, String>(); <<studdering is always good

      /*Adding elements to TreeMap*/
      tmap.put(1, "Data1");
      tmap.put(23, "Data2");
      tmap.put(70, "Data3");
      tmap.put(4, "Data4");
      tmap.put(2, "Data5");

      /* Display content using Iterator*/
      Set set = tmap.entrySet(); <<random obscure syntax... that is a
constructor for another class?
      Iterator iterator = set.iterator(); <<again, twice?
      while(iterator.hasNext()) {
         Map.Entry mentry = (Map.Entry)iterator.next();  <<What the heck
is this?
         System.out.print("key is: "+ mentry.getKey() + " & Value is:
"); <<How many levels of random systax does one need to just to do a loop?
         System.out.println(mentry.getValue());
      }

   }
}
