Question

Write a Java class (program) which inputs a simple integer and outputs a list of values from the input variable down to 0 (not including 0). You should only show every other value in the output, starting with the input value. You must use a for loop.

For example, if the input is 23, the output should be:

The input value was 23

23 

21

19

17

15

13

11

9

7

5

3

1

Code given:

import java.util.Scanner;

/**

  * This program counts down from the input number down to (but not including) 

  * 0, skipping alternate numbers.

  * 

  */

public class Countdown

{      

   /**

     * The entry point for the program.

     * 

     *  @param args The command-line arguments.

     */

  

   public static void main(String args[]) 

   {

       // Create a new Scanner object...

       Scanner scnr = new Scanner(System.in);

       

   }

}
