    <p>Here, try this:</p> <p>I think it pretty much does what you need.</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 = 0; double total = 0; Scanner entrada = new Scanner(System.in); System.out.println("Please enter the cost of the product."); cost = entrada.nextInt(); System.out.println("Please enter the amount of units to be sold"); number = entrada.nextInt(); cost_unit = cost * 1.4; if (number&gt;0) { total = cost_unit*number; } System.out.printf("Cost per unit will be $ %f\n",cost_unit); System.out.printf("Total cost will be $ %f\n",total); } } </code></pre> <p>Try it out and see if it works. By any chance are you at the ITAM?</p> <p><strong>EDIT</strong></p> <p>About the loop your original was correct. Just have to surround the code you want to repeat, and add a condition to exit.</p> <p>Something like this after creating the scanner ( pretty much the way you did in the first attempt ) :</p> <pre><code> while( cost &gt; 0 ) { System.out.println("Please enter the cost of the product ( 0 to exit the progam"); cost = entrada.nextInt(); ......... ......... ......... System.out.printf("Total cost will be $ %f\n",total) } </code></pre> <p>That will repeat the code between braces while cost is greater than 0.</p> <p>Of course you should change the initial value of cost, otherwise it won't enter in the lopp the first time and perhaps you should clean up the values before each iteration.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
