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);
  }
  }
