body: <p>Objects with the same attributes and methods belongs to the same class?</p>
  
  <ol>
  <li><p>Can't I declare two identical classes with the same methods and attributes, instanciate them and have "<strong>objects with the same attributes and methods belonging to different classes</strong>"?</p></li>
  <li><p>Can't I declare a class A and a sub-class B (children of the class A) both with the same methods and attributes (and don't declare any new attribute or method on the class B), instanciate them and have "<strong>objects with the same attributes and methods belonging to different classes</strong>"?</p></li>
  </ol>
  
  <p>This question is not about good practices... It's about the logical value (true or false) of the question on the title.</p>
