Assignment: Imagine you're developing a digital library system, which includes a base class Book with properties title $($String$)$ and pages $($int$),$ along with their respective public getters getTitle$()$ and getPages$().$ You are tasked with creating a subclass named Ebook that extends Book. This subclass adds an additional property, format $($String$),$ representing the ebook's format $($e$.$g$.,"$PDF$",$ "ePUB"$).$

Construct a variable named digitalRead of type Ebook, and instantiate it with an Ebook object that has the title "Advanced Java", $350$ pages, and is in the $"$PDF$"$ format. Assume the Ebook subclass has a constructor Ebook$($String title, int pages, String format$).$

Secondly, write a statement to declare an int variable named objectPages and set it to the attribute pages of the digitalRead object $($don$\text{'}$t use the hardcoded value $350$ here, but access the object property$).$
