Show key headers only | View raw
when i use the (reply = myScanner.findInLine(".").charAt(0);) method i get the following error message
Exception in thread "main" java.lang.NullPointerException
at Ifexercise1a.main(Ifexercise1a.java:18)
and i am sure i wrote it write cause i tried copying and paste it from another prog which is working fine, i am using eclipse and i don`t know if it`s a bug in eclipse or something wrong in the class itself.
the complete code is
import java.util.Scanner;
public class Ifexercise1a {
public static void main(String[] args) {
Scanner myScanner = new Scanner(System.in);
int age;
double price;
char reply;
System.out.println("how old are you?");
age = myScanner.nextInt();
System.out.println("you have a coupon? (Y/N)");
reply = myScanner.findInLine(".").charAt(0);
if(age <= 12 || age > 65){
price = 5.25;
}else{
price = 9.25;
}
if (reply == 'y' || reply == 'Y'){
price-=2.00;
}
System.out.println("you will pay $" + price);
}
}
