JAVA Scanner NoSuchElementException: No line found

Question

Sorry for baby question but I am very beginner. Please can you support with concern related to Scanner.

[BACKGROUND]: I wrote some code to study Scanner:

import javax.swing.JOptionPane;
import java.util.Scanner;

  class Main {
    public static void main (String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("What is day today? ");
        String day = scanner.nextLine();
        System.out.print("What is mounth today?");
        String mounth = scanner.nextLine();
        String outputText = "Today" + day + "mounth - " + mounth;
        JOptionPane.showMessageDialog(null, outputText);
               
    }
  
}

I have got an Exception: No line found. That is what I get in the output:

Task :run FAILED What is day today? Exception in thread "main" java.util.NoSuchElementException: No line found at java.base/java.util.Scanner.nextLine(Scanner.java:1651) at DemoOne.Main.main(Main.java:10)

FAILURE: Build failed with an exception.

I am using Apache NetBeans IDE 12.1. Looks like there is some of concern with System.in but I cannot understand how to fix it. Please support.

You just need to make sure you are using System.out.println()

When you ask what month it is, you only used System.out.print()

See below

 Scanner scanner = new Scanner(System.in);
        System.out.println("What is day today? ");
        String day = scanner.nextLine();
        System.out.println("What is mounth today?"); //right here
        String mounth = scanner.nextLine();
        String outputText = "Today" + day + "mounth - " + mounth;
        JOptionPane.showMessageDialog(null, outputText);
