Map
to fix the size, preventing add/remove. Any action that would change the size of the map is disallowed. The put method is allowed to change the value associated with an existing key however. If trying to remove or clear the map, an UnsupportedOperationException is thrown. If trying to put a new mapping into the map, an IllegalArgumentException is thrown. This is because the put method can succeed if the mapping's key already exists in the map, so the put method is not always unsupported.
