The PetDAO class is used for various database operations on the Pet entity.

Finish the findNamedPetsBySpecies method so that it returns all pets of the appropriate species. The method should not return any Pets whose name field is null. The method accepts a Hibernate Session object that it should use to make the query.

For example, if the Pets table contains:

id  name   species
--------------------
0   Lady   Dog
1   Max    Cat
2   null   Camel

calling findNamedPetsBySpecies with "Cat" as the species, should return a list that contains a pet named "Max" with the id 1.

Java SE 13, Hibernate 5.4  


  •   Example case: java.lang.UnsupportedOperationException at PetDAO.findNamedPetsBySpecies(PetDAO.java:11)
  •   All pets have names: java.lang.UnsupportedOperationException at PetDAO.findNamedPetsBySpecies(PetDAO.java:11)
  •   Some pets don't have names: java.lang.UnsupportedOperationException at PetDAO.findNamedPetsBySpecies(PetDAO.java:11)

Screening Applicants: The Good, the Bad and the Ugly

Since we’re all biased and we use incorrect proxies, why not just outsource hiring to experts or recruitment agencies? After all, they’ve been screening people for many years, so they must know how to do it right?

Not really. I was surprised to discover that many experts disagree with each other. Everybody praises their pet method and criticizes the others. Many of these methods look legitimate, but are based on...
