<li>[] This is in CONTRAST to other OOP languages where objects typically inheirit from Classes which define an objects properties and methods.<strong> </strong><strong>&nbsp;</strong></li>
</ol>
<li><strong>[+=] ADVANTAGE/BENEFIT/PRO of PI VS CBI&nbsp;</strong></li>
<ol>
<li>[] One advantages is the that memory footprint of a PI application can be much smaller because all object instances refer to the same method definition, whereas with CBI, every object instance has its own copy of every method definitions</li>
