This is a simple doubt .Here tree is of type Tree and it points to an object of pine .so in the output
tree is an instance of Pine ..that is fine .. tree is not an instance of Oak ..that is also fine.. tree is of type Tree ...is it right to say that tree is an instance of Tree..
coz in the output i get.. pine Tree Oops

Doubt is obvious. Ok Do you belive that every String is an Object Or Do you belive that every Chair or Table is a Furniture...??
If you DO then why, simply because String extends Object and ofcourse Chair is a Furniture (we can say Chair extends Furniture)
If we say that String is an object or Chair is a Furniture that means we say that String is an instance of Object or Chair is an instance of Furniture.
Similary every Pine is also instance of Tree you will get the same result if you try Pine isntanceof Object.......would'nt you?
Hence every subclass Object is ofcourse an instance of its super class
