Build Java Classes to implement the previous UML diagram.
* Instructions:
• The Item class is the Parent Class of Laptop and Book classes.
• The Laptop and Book classes are child classes of Item class.
• The purchaseDate data member is of the Date object type,
here you can find details of how to use the Date class.
• The viewFullDescription method must be overridden for each
child class to return a unique full detail.
• Build a main class called (ItemDemo) and create an array of
Item objects with different forms (i.e., polymorphism
approach).
