dictionary - How do I efficiently iterate over each entry in a Java Map?
Answer
Answer
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?
Answer
Map map = ...
for (Map.Entry entry : map.entrySet()) {
System.out.println(entry.getKey() + "/" + entry.getValue());
}
