Given these two functionally identical code samples in c# and java, what is the output?

C#:

public class A
{
  public String Method()
  {
    return "this is A";
  }
}

public class B : A
{
  public String Method()
  {
    return "this is B";
  }
}

A thisA = new B();

thisA.Method();

Java:

public class A
{
  public String Method()
  {
    return "this is A";
  }
}

public class B extends A
{
  public String Method()
  {
    return "this is B";
  }
}

A thisA = new B();

thisA.Method();

What does thisA.Method() return?

It turns out that there are two different answers to this. In .NET/C# it returns from A (“this is A”). In Java, it returns from B (“this is B”).

So far it appears that this is a type issue; new B() must be getting cast back to A in C#. Looking for some documentation on this specifically. Links anyone?

That’s right, our latest project turned into a pretty big effort; live election results for the entire US! We’re allowing you to customize which races you want to watch in real-time.

The idea for this project started back in August of 2010 as a simple site to show some local live election results for one county. It was a quick and simple application that worked really well.

In October, we started working on some improvements and decided to expand the scope of the results to cover all U.S. Senate, U.S. House races, and as many states as we could before November 2nd. Oh, and we redesigned the Silverlight UI and added a ton of functionality.

On top of that, the project now includes a mobile web version for the iPhone, Android, and Blackberry devices. And a custom Windows Phone 7 client application with some really advanced features. Not to mention a ton of new really smart high-availability back-end data services.

So, yeah, lots of work and not much sleep. But it’s really awesome and we’re very happy with it. Check it out: Live Election Results for November 2nd 2010.
