title: Is toString() only useful for debugging?
body: <p>Besides of course, their use with primitives. Most (if not all) of the implementations I see are only useful from a programmer viewpoint.</p>
  
  <hr>
  
  <p><em>EDIT</em>: I understand that I'm supposed to override the default behavior, that's why I mentioned implementations :). And I do get the value of overriding it in some components requiring a String representation inside a GUI. However, in the JDK at least, I see <em>lots</em> of implementations that only come to use whenever you need to debug the object instances.</p>
  
  <p>Why is it rooted at the Object class, since that is only seems useful for GUI/debugging stuff? are there other uses I'm not aware of?</p>
