Android Room @Delete with parameters

The beauty of room is, we play with the objects. As per requirement you can use for kotlin:

@Delete
fun delete(model: LanguageModel)

for Java:

@Delete
void delete(LanguageModel model)

it will delete the exact object which is stored in the db with the same values. LanguageModel is my model class and it works perfectly.

Actually, you can use @Query to perform a delete.

@Query("DELETE FROM users WHERE user_id = :userId")
abstract void deleteByUserId(long userId);

Extracted from Query javadoc:

UPDATE or DELETE queries can return void or int. If it is an int, the value is the number of rows affected by this query.
