Android : get data from SQLite in ascending order: android

I have below code to get data from SQLite database in android.

SystemCountryListDS system_country_list_ds;
system_country_list_ds.open();
List<SystemCountryList> system_country_list = system_country_list_ds.findAll();

I want to get this list in ascending order by country name. How can I do that?

I tried to do this on list:

Collections.sort(system_country_list);

It's giving me error:

inferred type is not within its bound; should implement java.lang.comparable
