Iterate through a HashMap What's the best way to iterate over the items in a HashMap? solution: Iterate through the entrySet like so: public static void printMap(Map mp) { Iterator it = mp.entrySet().iterator(); while (it.hasNext()) { Map.Entry pair = (Map.Entry)it.next(); System.out.println(pair.getKey() + " = " + pair.getValue()); it.remove(); // avoids a ConcurrentModificationException } } Read more on Map http://stackoverflow.com/questions/1066589/iterate-through-a-hashmap
