If I have an object implementing the Map interface in Java and I wish to iterate over every pair contained within it, what is the most efficient way of going through the map? Will the ordering of elements depend on the specific map implementation that I have for the interface? 4 46
How can I loop through all the entries in an array using JavaScript? 40 40
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 } }
I use a for loop to iterate the string and use charAt() to get each character to examine it. Since the String is implemented with an array, the charAt() method is a constant time operation. String s = “…stuff…”; for (int i = 0; i < s.length(); i++){ char c = s.charAt(i); //Process char } That’s what I would … Read more
