Adds all key/value pairs of other
to this map.
If a key of other
is already in this map, its value is overwritten.
The operation is equivalent to doing this[key] = value
for each key and associated value in other. It iterates over other
, which must therefore not change during the iteration.
void addAll(Map<K, V> other);
