The easiest way of adding menu items (to specify the options menu for an activity) is inflating an XML file into the Menu via MenuInflater. With menu_main.xml we can do it in this way:

• A.override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.menu.menu_main)
  }
• B.override fun onCreateOptionsMenu(menu: Menu): Boolean { menuInflater.inflate(R.menu.menu_main, menu) return true
  }
• C.override fun onOptionsItemSelected(item: MenuItem): Boolean {
  menuInflater.inflate(R.menu.menu_main, menu) return super.onOptionsItemSelected(item)
  }

If no any folder like res/anim-<qualifiers>, res/drawable-<qualifiers>, res/layout-<qualifiers>, res/raw-
<qualifiers>, res/xml-<qualifiers> exist in the project. Which folders are required in the project anyway? (Choose two.)

• A.res/raw/
• B.res/layout/
• C.res/xml/
• D.res/drawable/
• E.res/anim/

For example, we have a BufferedReader reader, associated with the json file through InputStreamReader. To get a file data we can do this:

• A.String line; try {
  while ((line = reader.readLine()) != null) { builder.append(line);
  }
  JSONObject json = new JSONObject(builder.toString());
  return json;
  } catch (IOException | JSONException exception) {
  exception.printStackTrace();
  }
• B.String line; try {
  while ((line = reader.readLine()) != null) { builder.append(line);
  }
  JSONObject json = new JSONObject(builder.toString());
  return json;
  } catch (RuntimeException|ArrayIndexOutOfBoundsException exception) {
  exception.printStackTrace();
  }
• C.JSONObject line; try {
  while ((line = reader.readJSONObject ()) != null) { builder.append(line);
  }
  JSONObject json = new JSONObject(builder.toString());
  return json;
  } catch (IOException | JSONException exception) {
  exception.printStackTrace();
  }

What do you want from Room when you create a DAO method and annotate it with @Delete?
Example:
@Dao
interface MyDao {
@Delete
fun deleteUsers(vararg users: User)
}

• A.Room generates an implementation that inserts all parameters into the database in a single transaction.
• B.Room removes a set of entities, given as parameters, from the database. It uses the primary keys to find the entities to delete.
• C.Room modifies a set of entities, given as parameters, in the database. It uses a query that matches against the primary key of each entity.
