title: Will implementation implement what it's interface extends?
body: <p>It's a very basic thing but the point is that I don't know it. My question is that will a class <strong>implicitly</strong> implement an interface, which is extended by the interface implemented by the class, <strong>explicitly</strong>. For example:</p>
  
  <pre><code>interface Foo extends Bar {
  }
  
  class FooImpl implements Foo {
  }
  </code></pre>
  
  <p>Now, will <code>FooImpl</code> be implementing <code>Bar</code> automatically ?</p>
