object of an interface? Hows possible

[Rahul Shilpakar]

Hi,

  

                  new Thread(
                           new Runnable()
                          { 
                               public void run()
                               {
                                    doStuff();
                               }
                               ).start();

 

The above code is compilable. I wonder how can we make object of Interface Runnable.
What is this concept? :evil:

Search for the term "anonymous class".

actually this is not an object of an interface however in a piece of code like this one you are extending/implementing the specified class/interface and then you override the needed methods. this method is named anonymos classes. and if you ever written swing code all your listeners are generally created in this way.
