Difference between save() and persist() in Hibernate

Save() and persist() both methods are used for saving object in the database. 

As per docs −

Save()  − Persist the given transient instance, first assigning a generated identifier. (Or using the current value of the identifier property if the assigned generator is used.) This operation cascades to associated instances if the association is mapped with cascade="save-update".

As per docs −

persist() −  Make a transient instance persistent. This operation cascades to associated instances if the association is mapped with cascade="persist". The semantics of this method are defined by JSR-220. 

Example of Save in Hibernate

@Entity
public class User {
   @Id
   Integer id;
   String name;
   public Integer getId() {
      return id;
   }
   public void setId(Integer id) {
      this.id = id;
   }
   public String getName() {
      return name;
   }
   public void setName(String name) {
      this.name = name;
   }
}
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import com.journaldev.hibernate.util.HibernateUtil;
public class SaveExample {
   public static void main(String[] args) {
      //get session factory to start transcation
      SessionFactory sessionFactory = HibernateUtil.getSessionFactory();
      Session session = sessionFactory.openSession();
      Transaction tx = session.beginTransaction();
      User user = new User();
      user.setId(1)
      user.setName("ABCD")
      session.save(user);
      //Close resources
      tx.commit();
      sessionFactory.close();
   }
}

Example of Persist in Hibernate

@Entity
public class User {
   @Id
   Integer id;
   String name;
   public Integer getId() {
      return id;
   }
   public void setId(Integer id) {
      this.id = id;
   }
   public String getName() {
      return name;
   }
   public void setName(String name) {
      this.name = name;
   }
}
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import com.journaldev.hibernate.util.HibernateUtil;
public class PersistExample {
   public static void main(String[] args) {
      //get session factory to start transcation
      SessionFactory sessionFactory = HibernateUtil.getSessionFactory();
      Session session = sessionFactory.openSession();
      Transaction tx = session.beginTransaction();
      User user = new User();
      user.setId(1)
      user.setName("ABCD")
      session.persist(user);
      //Close resources
      tx.commit();
      sessionFactory.close();
   }
}
