Question

in JAVA please

Some of the characteristics of a book are the title, authors, publisher, ISBN, price, and year of publication. Design the class Book so that each object can hold the following information about a book: title, up to four authors, publisher, ISBN, price, and number of copies in stock. To keep track the number of authors, you can add a variable; Including the methods to perform various operations on the objects of book. For example, the usual operations that can be performed on the title are to show the title, set the title, and check whether a title is an actual title of the book. In the similar way, the typical operations that can be performed on the number of copies in stock are to show the number of copies in stock, set the number of copies in stock, update the number of copies in stock, and return the number of copies in stock. Add similar operations for the publisher, ISBN, book price, and authors. Add the appropriate constructors. Write the definitions of the methods of the class Book based on the instruction in a). Write a program that uses the class Book and test various operations on the objects of class Book. Say declare an array of 100 components of the type book. Some the operations that you should perform are to search for a book by its title, search by ISBN, and update the number of copies of a book.
