Edit Question
Title
Body
Given the following code, with two alternative ways to iterate through it, is there any performance difference between these two methods? Map<String, Integer> map = new HashMap<String, Integer>(); //populate map //alt. #1 for (String key : map.keySet()) { Integer value = map.get(key); //use key and value } //alt. #2 for (Map.Entry<String, Integer> entry : map.entrySet()) { String key = entry.getKey(); Integer value = entry.getValue(); //use key and value } I am inclined to think that alt. #2 is the more efficient means of iterating through the entire map (but I could be wrong)
