    <p>I'm new to using Java, but I have some previous experience with C#. The issue I'm having comes with reading user input from console.</p> <p>I'm running into the "java.util.NoSuchElementException" error with this portion of code:</p> <pre><code>payment = sc.next(); // PromptCustomerPayment function </code></pre> <p>I have two functions that get user input:</p> <ul> <li>PromptCustomerQty</li> <li>PromptCustomerPayment</li> </ul> <p>If I don't call PromptCustomerQty then I don't get this error, which leads me to believe I am doing something wrong with scanner. Below is my full code sample. I appreciate any help. </p> <pre><code>public static void main (String[] args) { // Create a customer // Future proofing the possabiltiies of multiple customers Customer customer = new Customer("Will"); // Create object for each Product // (Name,Code,Description,Price) // Initalize Qty at 0 Product Computer = new Product("Computer","PC1003","Basic Computer",399.99); Product Monitor = new Product("Monitor","MN1003","LCD Monitor",99.99); Product Printer = new Product("Printer","PR1003x","Inkjet Printer",54.23); // Define internal variables // ## DONT CHANGE ArrayList&lt;Product&gt; ProductList = new ArrayList&lt;Product&gt;(); // List to store Products String formatString = "%-15s %-10s %-20s %-10s %-10s %n"; // Default format for output // Add objects to list ProductList.add(Computer); ProductList.add(Monitor); ProductList.add(Printer); // Ask users for quantities PromptCustomerQty(customer, ProductList); // Ask user for payment method PromptCustomerPayment(customer); // Create the header PrintHeader(customer, formatString); // Create Body PrintBody(ProductList, formatString); } public static void PromptCustomerQty(Customer customer, ArrayList&lt;Product&gt; ProductList) { // Initiate a Scanner Scanner scan = new Scanner(System.in); // **** VARIABLES **** int qty = 0; // Greet Customer System.out.println("Hello " + customer.getName()); // Loop through each item and ask for qty desired for (Product p : ProductList) { do { // Ask user for qty System.out.println("How many would you like for product: " + p.name); System.out.print("&gt; "); // Get input and set qty for the object qty = scan.nextInt(); } while (qty &lt; 0); // Validation p.setQty(qty); // Set qty for object qty = 0; // Reset count } // Cleanup scan.close(); } public static void PromptCustomerPayment (Customer customer) { // Initiate Scanner Scanner sc = new Scanner(System.in); // Variables String payment = ""; // Prompt User do { System.out.println("Would you like to pay in full? [Yes/No]"); System.out.print("&gt; "); payment = sc.next(); } while ((!payment.toLowerCase().equals("yes")) &amp;&amp; (!payment.toLowerCase().equals("no"))); // Check/set result if (payment.toLowerCase() == "yes") { customer.setPaidInFull(true); } else { customer.setPaidInFull(false); } // Cleanup sc.close(); } </code></pre>

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.
