What does this code mean ?

Question

Handler myHandler = new Handler();
myHandler.post(new Runnable() {
//some code });

My question is what's "new Runnable()" here ? Is it a nameless object of class Runnable ?
Can someone break this code down , like create a real object from Runnable() and call that object in post () method by name.

Runnable is an interface not a class but we can create an object of interface like in this case

new Runnable () {

}

But there is a difference in object creation of class and interface. In an interface we need { } block to implement all methods but in an object of class there is no { }. There is paranthesis () which used to pass the arguments in method.

Looks somehow related to this too:

I'll leave further explanations for the experts.

Edit:
P.S: Can you share the full code, maybe give some more context to it?

Runnable is an interface to create threads.
