The Set Class in C++ and Java

[coosa]

Dear all,

I'm familiar with the Set Class in C++ and Java; however, i have been
searching in C# for a similar container as in c++ or collection as in
java, but couldn't find one.
Could some one tell me about the the Set implementation inside .NET?

Best regards

[Kevin Spencer]

Re: The Set Class in C++ and Java

There is no equivalent in C# for the Java Set class, unfortunately. I did,
however, come across an excellent implementation of a Set class here:

The link works from here, but I wouldn't bother using the class as it is not
typesafe at all, items in the set are added and removed as objects.

I am able to download the file. I don't know where you got the URL for the
file that you posted, because the link I used was an ASP.Net Control on the
page which performs a PostBack to retrieve the file. If you look on the page
near the top of the article, you will see the following text:

Download This Tool: Set.cs

The text "Set.cs" is the hyperlink to download the code. I would post it
myself, but I'm not sure that would be kosher, since I was not the author.

My bad, my mozilla firefox prevented the scripts for the page, so i
couldn't download it! :-)
any way, i have checked the file; it doesn't first implement generics
and doesn't really consider strong typing.
Any way; i really hope that Microsoft comes out with a Set
implementation in their future releases.
As an alternative, i see the HashTable, but considering a constantly
sorted range complexity of the tree, a HashTable is not always the
better choice since the fast lookup is what makes it very powerful.

The Java Set Interface is not strongly-typed either. In fact, it can contain
any combination of data in it, not just one type. See
http://java.sun.com/j2se/1.4.2/docs/.../util/Set.html. I saw quite a
number of other C# Set Class implementations (see
http://www.google.com/search?hl=en&q=C%23+Set+Class), but the one that I
pointed you to was the closest one to the Java Set Interface, which I
thought was what you were looking for.

In any case, you are free to create your own Collection classes, derive from
any existing Collection class, and implement whatever functionality you
desire. Perhaps, considering your desire for strong typing, you might want
to start from one of the System.Collecti ons.ObjectModel
(http://msdn2.microsoft.com/en-us/lib...jectmodel.aspx)
or System.Collecti ons.Generic
(http://msdn2.microsoft.com/en-us/lib...s.generic.aspx)
namespace classes.

Well, that was pre-generics in Java. Look at:

Just to clarify :)

Re: The Set Class in C++ and Java

Understood, Jon. However, I do think that the ability to include instances
of multiple types is useful, and of course, this is still possible with the
generic Set class if you define the type as object.

That is not true at all,

Since JDK 1.5 Update 2, Java came up with alot of stong typed generics
including the vector , set, ...etc. classes.
Earlier you could not for instance use a statement in Java like this:
java.util.Vecto r <SomeClassv; It took every thing as object and u
needed to cast. However, as from Update 2 i guess of 1.5 jdk, they
adapted the STL implementation of strong typing.

Generics were in Java 1.5 from the start. It was not added
in update 2.

Java generics and C++ STL are not the same.

I'm aware they are not the same, but so far i recall the adding of a
template class for the Vectors in java by update 2 <since i by 1.5 i
couldn't find such in the api until i downloaded update 2.
But whether update 1, 2 or from the star tof 1.5, i just wanted to say
that Java supports generics

I still have the first release of 1.5 installed.

Vector is generic.

They do not add new functionality to updates, they only
fix bugs.

As far as I'm aware Java generics are just syntactic sugar enforced at
compile time, but the resultant code will still be a collection of
Objects.

C# generics result in a collection of the correct type, so I generic
list specified as <intwill actually be a list of ints with no
boxing/unboxing required.

(I am not saying that one language is better than the other, just
pointing out a difference)
