Program to read two integer and print product of them

This program asks user to enter two integer numbers and displays the product. To understand how to use scanner to take user input, checkout this program: Program to read integer from system input.

import java.util.Scanner;

public class Demo {

    public static void main(String[] args) {

        /* This reads the input provided by user
         * using keyboard
         */
        Scanner scan = new Scanner(System.in);
        System.out.print("Enter first number: ");

        // This method reads the number provided using keyboard
        int num1 = scan.nextInt();
        
        System.out.print("Enter second number: ");
        int num2 = scan.nextInt();

        // Closing Scanner after the use
        scan.close();
        
        // Calculating product of two numbers
        int product = num1*num2;
        
        // Displaying the multiplication result
        System.out.println("Output: "+product);
    }
}

Output:

Enter first number: 15
Enter second number: 6
Output: 90
