Using Java language, figure out a solution to the following. Thanks

A college bookstore wants to estimate its business for next term. Experience has shown that sales for a course textbook depend greatly on whether a book is required or just suggested reading, and whether or not it has been used for a course in previous terms. The bookstore tells you that a new, required book will sell to 90% of prospective course enrollment, but if it has been used before, only 65% will buy. Similarly, 40% of the prospective enrollment will buy a new, suggested book, but just 20% will buy a book which is suggested and is old.

Write a program that takes as input a book\'s identification number, the book\'s single-copy cost (the price the store pays to buy the book from its supplier), the current number of volumes on hand, the prospective course enrollment (for a particular course), and data that indicates whether the textbook is required or suggested, as well as whether it is new or old. As output, first give the number of books that must be ordered (if any). Then, if books must be ordered, show the total cost the store must pay for the books ordered, and the expected profit on the books ordered assuming that the store pays 80% of list price to obtain them from its supplier, and sells them for list price.

This program requires that you read in the following data values: z book ID number (an integer) z cost per copy (a real number) z volume on hand (an integer) z expected enrollment (an integer) z code for required versus suggested (a character, \'R\' or \'S\') z code for new versus used (a character, \'N or \'O\')

Thank You
