Trying to add API to room database. Not sure if I am creating the data classes correctly. Getting this error public final class DatabaseBitcoin {
^
Tried the following constructors but they failed to match:
DatabaseBitcoin(int,com.example.paywithbitcoin.database.Time,java.lang.String,java.lang.String,java.util.List<com.example.paywithbitcoin.database.Currency>) -> [param:id -> matched field:id, param:time -> matched field:unmatched, param:disclaimer -> matched field:disclaimer, param:chartname -> matched field:chartname, param:bpi -> matched field:unmatched]/Users/drsilaswiggin/dev/kotlin/PayWithBitcoin/app/build/tmp/kapt3/stubs/debug/com/example/paywithbitcoin/database/DatabaseBitcoin.java:7: error: Entities and Pojos must have a usable public constructor. You can have an empty constructor or a constructor whose parameters match the fields (by name and type).

To make it work you need default constructor, so at least you need default value for time and bpi, otherwise it cannot be created from database data
