title: Java and Ruby: "everything is an object" in OO?
body: <p>Is everything in Java an object, the way it is in Ruby?</p>
  
  <p>Books, tutorials, everything states "everything in Ruby is an object", but is that common for object oriented languages?</p>
  
  <p>Is everything an object is Java as well, or is object oriented just a paradigm of programming, and it doesn't mean that everything is or evaluates to an object?</p>
