      error: cannot find symbol
                courses.save(course);
                       ^

According to Interface PagingAndSortingRepository, there is no save method in this interface. Hence your code is failing.

But Interface CrudRepository has a save method.

Also, this hierarchy might help to clear the picture even more:

Why not use JpaRepository and have best of both worlds! – hiren Dec 28 '22 at 11:49
Yes you could as the java doc of the PagingAndSortigRepository Interface suggests. https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/repository/PagingAndSortingRepository.html#:~:text=Repository%20fragment%20to,Author%3A – Tr1monster Dec 28 '22 at 11:51

PagingAndSortingRepository repository has mainly been created for fetching records and not modify it.

In this case your repository interface can extend both PagingAndSortingRepository & CrudRepository

All your links go to the javadoc for `CrudRepository` – tgdavies Jul 20 '23 at 04:37
You can extend both of them : public interface YourRepository extends PagingAndSortingRepository, CrudRepository – amine Aug 16 '23 at 13:44
