Book store project using an array

Suppose you are a Bookseller. You have 3 items of books like java, C, and Python. You give Discount to your customer as .2% for teacher  .3% for student .5% for wholesale.

Your program will ask your customer which book he needs. Then the program will ask who is he or she, teacher, student, or wholesaler.



Code:
import java.util.Scanner; public class BookStor { static Scanner myScanner= new Scanner(System.in); static String[] books={"Java","C","Python"}; static final double studentDiscount = .3; static final double teacherDiscount = .2; static final double wholesaleDiscount = .5; public static void main(String[] args) { Scanner myScanner= new Scanner(System.in); prln("--------------Welcome---------------"); prln("Which book you want?/n Ans:"); String choice = myScanner.nextLine(); if (books[0].toLowerCase().endsWith(choice.toLowerCase())) { prln("You want"+ books[0] +" book"); calculateResult(books[0]); } else if (books[1].toLowerCase().equals(choice.toLowerCase())) { prln("You want "+ books[1] +" book"); calculateResult(books[1]); } else if (books[2].toLowerCase().equals(choice.toLowerCase())) { prln("You want"+ books[2]+ " book"); calculateResult(books[2]); } else { prln("We don't have this one!!!"); } } static void calculateResult(String result){ prln("Are you a Teacher / Student / Wholesale? \n Ans:"); String ans = myScanner.nextLine(); double piz = 200; if (ans.toLowerCase().equals("teacher")) { prln("Your prise is: "); piz = piz -(piz* teacherDiscount); showPrice(piz); } else if (ans.toLowerCase().equals("student")) { prln("Your prise is: "); piz = piz -(piz* studentDiscount); showPrice(piz); } else if (ans.toLowerCase().equals("wholesale")) { prln("Your prise is: "); piz = piz -(piz* wholesaleDiscount); showPrice(piz); } else { prln("Your prise is: "+piz); } } static void showPrice(double piz){ prln("Your total cost is: "+piz); prln("=======Thankyou========="); } static void prln(Object anyObject){ System.out.println(anyObject); } }
