Help Need To Correct Java Code
<p>I have this but there is an error, I don't get it :(. I'm relatively new to Java.</p>

<pre><code>package hw;
import java.util.Scanner;

public class Problem1
{
    public static void main (String [] args)
    {
        int cost; int number; double cost_unit; double total;

        Scanner entrada = new Scanner(System.in);            

        System.out.println("Please enter the cost of the product.");
        cost = entrada.nextInt();

        while (cost&gt;0){

            System.out.println("Please enter the amount of units to be sold");
            number = entrada.nextInt();

            if (number&gt;0);

            cost_unit = cost * 1.4;
            total = cost_unit*number;

            System.out.printf("Cost per unit will be $ %d\n",cost_unit);
            System.out.printf("Cost per unit will be $ %d\n",total);                                
        }
    }                
}
</code></pre>

<p>// I just want the user to enter the cost for a product, give a number of units to be ordered, and I want the program find out the final price of the product with a 40% profit.</p>
