The following link gives some comparative values of cube vs cylinder strengths... .
Cylinder strength is lower than cube strength due to the geometric properties of the samples .
As far as I'm aware there is no mathematical formula for converting between the two .

In an OO component, when you have only one implementation available for an class and that class is not 'published' to other components, is it still advisable to have an interface and work with the interface instead?
I am fully aware of 'programming to...
Answer Snippets (Read the full thread at stackoverflow):
The alternative to that would be to not use the interface and subclass the concrete class....
Creating interfaces for concrete types is a delicate balancing act as you can easily create with the interface as opposed to the concrete class.

General contractor has put in 2 garage pads with footings and the bill is quite high. We were referred to him & I'd gotten prices from the other gc's in the area so we knew approx how much it should be.
The concrete alone was a total of $9290 w/concrete...

What kind of loads and guidelines were thats rediculous....
The concrete and air entrained and the concrete is more than $80.00/yard.
The excavating, compacted base and forming costs in addition to the amount of concrete needed.

In C# , when I have an interface and several concrete implementations, can I cast the interface to a concrete type or is concrete type cast to interface?
What are the rules in this case?
Thanks

Access to the concrete classes which is one major reason to have an interface in the first place (down)cast an interface to a concrete implementation, iff the reference you cast actually is a reference to the specific concrete implementation....

Needing some advise on what should be done with my little sister's concrete front porch. I'd like to think of myself as the king DIYer, but this one is probably best left to the pros.
Here's the facts:

- Porch area...

How would design and organize tests for the concrete methods of an abstract class? Specifically in .NET.

Answer Snippets (Read the full thread at stackoverflow):
You have to create a subclass that implements the abstract methods (with empty methods), but none of the concrete ignore the overridden abstract methods....
The first thing that comes to mind is to test those methods in a concrete child class.

Are there some practical programming situations for someone to declare a class abstract when all the methods in it are concrete?

To facilitate implementation of your concrete classes you might want to provide an abstract class providing default behavior for each method....
They cannot be instantiated so if you have an abstract class with concrete methods then it can.

I have class with a forwarding method foo:
void foo( Concrete c, String s ) { c.bar( s ); }
I wish to test that foo in fact forwards. Unfortunately for me, Concrete is a class in a third-party library, and is a Concrete type, not an interface. Thus I ...

For Concrete like this:
public class ConcreteStub extends Concrete { public int numCallsToBar = 0 , it is more complicated and the answer depends on the complexity of Concrete and your project's use of the Concrete class.

I'm drawing some UML in which a concrete class inherits from an abstract class which defines a pure virtual method. Is it required to show this method in the concrete class as well? It's implied by inheriting from the abstract class.

The best guide I know of for UML is UML Distilled by Martin Fowler... .
In fact, in general, don't put any more in the UML than you must have to clarify what you're saying, unless you're (god forbid) trying to generate code from it .
Nope, you don't need to.
