# addEntries method Null safety

void addEntries (

1. Iterable<MapEntry<K, V>> newEntries

)

Adds all key/value pairs of `newEntries` to this map.

If a key of `newEntries` is already in this map, the corresponding value is overwritten.

The operation is equivalent to doing `this[entry.key] = entry.value` for each MapEntry of the iterable.

## Implementation

    void addEntries(Iterable<MapEntry<K, V>> newEntries);
