findInLine

[noisepoet]

Can anyone tell me why this code doesn't compile? It has something to do with the line that reads: reply = myScanner.findI nLine(".").char At(0);

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!");
	}
}

compiles OK but has nullpointer exception - try replacing

     reply = myScanner.findInLine(".").charAt(0);

with

     reply = myScanner.findWithinHorizon(".",0).charAt(0);

haha this is from java for dummies right? even i've been trying to figure out the same problem, but its probably coz the author has worked on an older version of java, and that makeshift method of his is no longer valid...gonna try out the suggestion put here and lets see if it works...
the problem has something to do with the 0 in charAt, coz that doesnt seem to accept null values any more...

UPDATE : ok i tested the suggestion here and it does work...thanks a lot...
