Hello Jan Kalasnikov
entrySet() method is from the Map Interface.
When called on a Map<Key,Value> object it returns a Set<> Object containing all the keys and values.
You can then easily iterate on the returned Set<> object using the for-each loop and an object of type Map.Entry<Key, Value> will be returned with each iteration. You can then use the Map.Entry<Key, Value> to get the key and the value for each entry on the Map.
