    Default Trouble calculating a product and allowing a user to specify a range

    I'm in a beginning programming class and am having trouble with this question:
    Write an application that gives you the product of odd integers from 3 to 35. Now change your program to allow a user to specify a range to calculate.

    So far, I have-

    package HMWK; //


    import javax.swing.*;

    public class HMWK {

    public static void main( String args[] )
    {
    int product = 1;int num1; String input;

    input= JOptionPane.showInputDialog ("Enter your number");
    num1= Integer.parseInt(input);

    for ( int x = 0; x <= 15; x += 2 )
    product *= x;


    JOptionPane.showMessageDialog( null, "Your product is " + product,
    "Odd Product", JOptionPane.INFORMATION_MESSAGE );

    System.exit( 0 );
    }

    What does your program do? Does it compile? Does it run? Does it give you any errors? Does it do what you expect? Where are you stuck?
