When use getOne and findOne methods Spring Data JPA
...a-Jpa modified findOne().
Previously, it was defined in the CrudRepository interface as :
T findOne(ID primaryKey);
Now, the single findOne() method that you will find in CrudRepository is which one defined in the QueryByExampleExecutor interface as :

Difference between “managed” and “unmanaged”
...rs is 'unmanaged code'. Also, since it compiles to machine code and not an intermediate language it is non-portable.
No free memory management or anything else the CLR provides.
Since you cannot create unmanaged code with Visual Basic or C#, in Visual Studio all unmanaged code is written in C/C++....
Normalization in DOM parsing with java - how does it work?
...
@user2043553, the newlines are actually the point there. Without newlines, you wouldn't see the difference. If you shouldn't have understood: Normalization "corrects" the XML so one tag is interpreted as one element. If you didn't do that, it might happen that these very...
Namespace + functions versus static methods on a class
...t: In C++ functions in the same namespace as a class belong to that class' interface (because ADL will search those functions when resolving function calls).
Namespaced functions, unless declared "friend," have no access to the class' internals, whereas static methods have.
This means, for example...

When is it right for a constructor to throw an exception?
...
The constructor's job is to bring the object into a usable state. There are basically two schools of thought on this.
One group favors two-stage construction. The constructor merely brings the object into a sleeper state in which it refuses to do any work. There's an a...
async/await - when to return a Task vs void?
... represent top-level async operations, and have additional rules that come into play when your task returns an exception. The easiest way is to show the difference is with an example:
static async void f()

await h();
}
static async Task g()
{
await h();
}
static async Task h()

The array+evaluator will represent the same logic as one of your functions, but only the evaluator will be code. The array is "data" and can be either generated at runtime or saved on disk and ...
What is a Windows Handle?
...organize physical memory transparently to the program. Resolving a handle into a pointer locks the memory, and releasing the handle invalidates the pointer. In this case think of it as an index into a table of pointers... you use the index for the system API calls, and the system can change the po...
