Assignment:

Enhance your CinemaPrice assignment from last week by adding a while loop that continues to prompt the user for their age (instead of randomly generating as in the previous version) until a zero is entered.

This is called using a sentinel value (0).

Example output:

 Please enter the cinema ticket price: 15.00 Please enter age (0 to quit): 10 Your age : 10 Your ticket price is $7.50 which is half price. Please enter age (0 to quit): 24 Your age : 24 Your ticket price is $15.00 which is full price. Please enter age (0 to quit): 0 Good bye 

My Script so far:

import java.text.NumberFormat;

import java.util.Random;

import java.util.Scanner;

public class CinemaPriceEnhanced {

public static void main(String[] args) {

Random gen = new Random( ); //Creates a random generator

int age = gen.nextInt(100) +1; // Random generator between the #1-100

NumberFormat nFmt = NumberFormat.getCurrencyInstance(); // Returns a currency format

Scanner scan = new Scanner(System.in);

System.out.println("Welcome to the Cinema Price Calculator");

System.out.println("--------------------------------------");

System.out.println("Please enter the full cinema ticket price: "); // User puts in a ticket price

double price = scan.nextDouble();

System.out.println("Please enter age (0 to quit): " + age);

System.out.println("Your age: ");

age = scan.nextInt();

while (age <5) // Generates ticket price based on random age

{

price = 0.0;

System.out.println("Your ticket price is $0.00 which is free.");

age++;

}

if (age >=5 && age <=13)

{

System.out.println("Your ticket price is " + nFmt.format(price/2) + " which is half price.");

age++;

}

else if (age >=14 && age <60)

{

System.out.println("Your ticket price is " + nFmt.format(price) + " which is full price.");

age++;

}

else

{

System.out.println("Your ticket price is " + nFmt.format(price = price - 1.10) + " which is the senior discount price.");

age++;

}

System.out.println("Good bye");

scan.close();

}

}

My Output:

Welcome to the Cinema Price Calculator

--------------------------------------

Please enter the full cinema ticket price:

12

Please enter age (0 to quit): 58

Your age:

58

Your ticket price is $12.00 which is full price.

Good bye

My Question is, how do I get it to continue looping until it gets to zero? Thanks.
