It gives error since I closed the scanner in main method but I created a new scanner in the method

Question

i tried to creating a new scanner after i closed the former in the main. but it gives error. i thought that i created a new scanner in the method than i closed it so it would read the new inputs through my method but it did not. what is the issue here? chatgpt couldn't illuminate me :(

package gross_calculator;

import java.util.Scanner;

public class GrossPayCalculator {
    
    static void story() {
        
        System.out.println("Which season the day is of?");
        Scanner scanner1 = new Scanner(System.in);
        String season = scanner1.nextLine();
        System.out.println("How is that day?");
        String adjective = scanner1.nextLine();
        System.out.println("What is the number?");
        int number = scanner1.nextInt();
        System.out.println("On a "+adjective+" "+season+" day,\nyou read "+number+" pages of book.");
        scanner1.close();
    }
    
    public static void main(String[] args) {
        
        int hours = 0;
        System.out.println("How many hours did you work?: ");
        Scanner scanner = new Scanner(System.in);
        hours = scanner.nextInt();
        
        double payRate = 0;
        System.out.println("What is your pay rate?: ");
        payRate = scanner.nextDouble();
        
        scanner.close();
        
        double grossPay = hours*payRate;
        System.out.println("Gross pay: "+grossPay);
        
        story();
    }

}

error message:

What is your pay rate?:

Answer 1

Use a single Scanner object, and don't close it since you are reading from System.in

See the comments on this answer for further clarification.

package gross_calculator;

import java.util.Scanner;

public class GrossPayCalculator {

    private static void printStory(Scanner scanner) {
        System.out.println("Which season is it?");
        String season = scanner.nextLine();
        System.out.println("How is the day?");
        String adjective = scanner.nextLine();
        System.out.println("Enter a number:");
        int number = Integer.parseInt(scanner.nextLine());
        System.out.println("On a " + adjective + " " + season + " day, you read " + number + " pages of a book.");
    }

    private static double calculateGrossPay(Scanner scanner) {
        System.out.println("How many hours did you work?: ");
        int hours = Integer.parseInt(scanner.nextLine());
        System.out.println("What is your hourly pay rate?: ");
        double payRate = Double.parseDouble(scanner.nextLine());
        return hours * payRate;
    }

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        double grossPay = calculateGrossPay(scanner);
        System.out.println("Gross pay: " + grossPay);
        printStory(scanner);
    }
}

Example Usage:

How many hours did you work?: 
8
What is your hourly pay rate?: 
100
Gross pay: 800.0
Which season is it?
Spring
How is the day?
Sunny
Enter a number:
42
On a Sunny Spring day, you read 42 pages of a book.
