Trying to learn java, I have a problem.
In the code I have a problem with this I think
price -= 2.00; (is there some other - that I should be using? because this doesn't work)
its not subtracting the 2.00 it skips it and ends.
this is the error i get when I compile. type Y to have a coupon.
Have a coupon? (Y/N) Exception in thread "main" java.lang.NullPointerException
at TicketPriceWithDiscount.main(TicketPriceWithDiscount.java:14)
import java.util.Scanner;
class TicketPriceWithDiscount {
public static void main(String args[]) {
Scanner myScanner = new Scanner(System.in);
int age;
double price = 0.00;
char reply;
System.out.print("How old are you? ");
age = myScanner.nextInt( );
System.out.print("Have a coupon? (Y/N) ");
reply = myScanner.findInLine(".").charAt(0);
if (age >= 12 && age < 65) {
price = 9.25;
}
if (age < 12 || age >= 65) {
price = 5.25;
}
if (reply == 'Y' || reply == 'y') {
price -= 2.00;
}
if (reply != 'Y' && reply != 'y' &&
reply!='N' && reply!='n') {
System.out.println("Huh?");
}
System.out.print("Please pay $");
System.out.print(price);
System.out.print(". ");
System.out.println("Enjoy the show!");
}
}
