then the <code>File</code> interface is implemented by both <code>S1</code> and
<code>S2</code>, regardless of what other methods
<code>S1</code> and <code>S2</code> may have or share.

<p>
Every type that is a member of the type set of an interface implements that interface.
Any given type may implement several distinct interfaces.
