Does the Map class implement the Iterable interface and can it be iterated over in a for-each loop?

The Map interface in Java does not inherit from the Iterable interface. This means that objects of type Map cannot be directly iterated over in a for-each loop.

However, Map has methods that return collections implementing Iterable, such as:

• keySet() — returns a set of keys,
• values() — returns a collection of values,
• entrySet() — returns a set of key-value pairs (Map.Entry).

These collections can be iterated over in a for-each loop.

Example of iterating over Map elements:

Map<String, Integer> map = new HashMap<>();
map.put("one", 1);
map.put("two", 2);

for (Map.Entry<String, Integer> entry : map.entrySet()) {
    System.out.println(entry.getKey() + " = " + entry.getValue());
}
