I have created a code to accept 10 integers into a stack and a queue and then print the output simultaneously removing items from both.

I can enter the inputs for both stack and queue, but there is no output shown.

Why is this and how can I resolve it?

Below is the code :

Code:

import javax.swing.*;
import static javax.swing.JOptionPane.*;

public class StacknQueue {
    public static void main(String args[]){
        StackArrayBased stack = new StackArrayBased();
        QueueArrayBased queue = new QueueArrayBased();
    
    
    for(int i=0; i<11; i++){
        stack.push(showInputDialog("Enter an integer into Stack :"));
        queue.enqueue(showInputDialog("Enter an integer into Queue : "));
    }
    
   System.out.println("\n Numbers stored in Stack \n");
   while((!stack.isEmpty())){
       System.out.println((String)stack.pop());
   }
   System.out.println("\n Numbers stored in Queue \n");
   while((!queue.isEmpty())){
       System.out.println((String)queue.dequeue());
   }
    
}
}
