Question

Create the java program called Product that prompts the user to enter names of hardware devices. The program includes a sentinel loop with a value of ### that stops the input from the user. Include a counter variable called inputnum inside the loop, that counts the number of hardware devices the user entered. Using a system statement inside the loop, display the names of hardware devices the user entered. Include a dialog box outside the loop that displays the counter variable value (number of hardware device names entered by the user).

Answer 1

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

public class Product {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        long inputnum = 0;
        String s = "";
        while (!s.equalsIgnoreCase("###")) {
            System.out.println("Enter name of hardware device");
            if (!(s = scanner.nextLine()).equalsIgnoreCase("###")) {
                System.out.println("Hardware device: " + s);
                inputnum++;
            }
        }
        JOptionPane.showMessageDialog(null, "Number of entered names: " + inputnum);
    }
}
