Problem Statement  A Book has such properties as title, author, and numberOfPages. A Volume will have properties such as volumeName, numberOfBooks, and an array of book objects (Book [ ]). You are required to develop the Book and Volume classes, then write an application (DemoVolume) to test your classes. The directions below will give assistance.  Create a class called Book with the following properties using appropriate data types: Title, Author, numberOfPages, Create a second class called Volume with the following properties using appropriate data types: volumeName, numberOfBooks and Book [ ]. The Book [ ] contains an array of book objects.   Directions  Create a class called Book with the following properties using appropriate data types: Title, Author, numberOfPages, The only methods necessary in the Book class, for this exercise, are the constructor and a toString(). Create a second class called Volume with the following properties using appropriate data types: volumeName, numberOfBooks and Book [ ]. Book [ ] will contain an array of book objects. The only methods necessary in the Volume class, for this exercise, are the constructor, toString() and getBookArray(). The getBookArray returns a string of book properties for each book. Create an application called DemoVolume In the main method, Create an array of book objects to be added to the volume Create a volume object called volume1 Display the properties of volume1 Document each statement concisely.
