Using interfaces in java..Newb question
<p>Suppose there in an interface Displaceable and a class Circle which implements Displaceable. Displaceable has a method named move() which of course is implemented in Circle.</p>

<p>What would happen in the following scenario?</p>

<pre><code>Circle a =  new Circle(..);
Displaceable b = a;
b.move()
</code></pre>

<p>Would the object refer to the Circle's move method?</p>
