Today, you will use features of Reflection in Java programming language to examine and manipulate internal properties of the library program written in the previous labs $($use the first version

without subsequent modifications$).$

Create an object of Class for the Book class created during the last lab, using forName$()$

method which takes the name of the class to be reflected as its argument. Create it also using

getClass$()$ method and $.$class extension. You will use this object to get information about the

corresponding class at runtime. Using object of the getClass$()$ get and print all the declared

methods of Book. To this end, create an object of the Method class, looping over all declared

methods, get names of methods, get the access modifier of methods and get the return types for

each method.

Add the private field pagesNr to the Book class and set its default value as $100.$ Use Reflection

to get and to modify the value of this private field. Likewisely with methods, list and inspect all

the fields with their access modifiers in the Book class.

Get the superclass for Book class, using Reflection, and inspect all methods and fields of the

superclass.

Add the private constructor and the public constructor for the Book class with different number

of arguments as the original constructor. The constructurs should set some arguments with default

values, while leaving the others, you can add some extra fields to the class. Using Reflection, find

the information about the constructors of the class.
