Recently, If you are using Hibernate 5.2 or higher, then the Query::list() method has been deprecated.
Now, what the difference in using these two methods?
If anyone knows, please explain with examples.

getSingleResult() Execute a SELECT query that returns a single untyped result. boolean.
getResultList() returns an empty list instead of null . So check isEmpty() in the returned result, and continue with the rest of the logic if it is false. Save this answer.
The documentation of Hibernate 3.2 says that Query#list() returns the query as List<T>.
Return the query results as a List. If the query contains multiple results pre row, the results are returned in an instance of Object[].
As you can read from the newer documentation of Hibernate 5.2 about the same named class and its method Query#getResultList is the overridden implementation of the the javax interface's method TypedQuery#getResultList.
Execute a SELECT query and return the query results as a typed List.
This method is a replacement of the one from the previous versions.
The idea is to implement Java EE interface (most of javax library) and keep the naming consistent.
