WRITE A PROGRAM THAT STORES THE DETAILS OF THE SOFTWARE AND HARDWARE BOOKS. THE SOFTWARE BOOKS INCLUDES THE SOFTWARE VERSION AND SOFTWARE NAME. THE HARDWARE BOOK INCLUDES THE HARDWARE CATEGORY AND PUBLISHER. HOWEVER, BOTH THE BOOKS INCLUDE SOME COMMON DETAILS, SUCH AS AUTHOR NAME,TITLE,PRICE,AND NUMBER OF PAGES. THEREFORE, YOU NEED TO STORE AND DISPLAY THE BOOK DETAILS BY IMPLEMENTING THE CODE REUSABILITY IN THE PROGRAM.



ANSWER



class book {
   
   string author;
   string title;
   int price;
   int pages;
   int stock;

    public void getdetails(string at, string tt, int pr, int pg, int st) {
       author = at;
       title = tt;
       price = pr;
       pages = pg;
       stock = st;
   }
      public void showdetails () {
       system.out.println (" ");
       system.out.println ("books information");
       system.out.println ("============================");
       system.out.println (" book author: " + author);
       system.out.println (" book title: " + title);
       system.out.println (" book price: " + price);
       system.out.println (" number of pages: " + pages);
       system.out.println (" book of stock: " + stock);
  }
   
}
    class hardwarebook extends book {

    }
         public void showdetails() {
           system.out.println (" ");
           system.showdetails ();
           system.out.println ("hardware category: " + hardwarecategory);
