System.out.print-method doesn´t work right
<p>I am doing excercises in a book called "Java, how to program". I have created a small program with 2 classes. The program is supposed to be used by a hardware store to represent an invoice for items sold. It is supposed to includ 4 pieces of information: A string value for the items number, a string value which describes the product, an int value for the quantity of items sold, and a double value for the items price. I have created 2 objects of the class in a class which contains the main method. I am supposed to use "set and get-methods" for each instance variables.</p>

<p>The problem is that when the programs prompts the user to write the values of the variables, it doesn´t read the first value for the variable "second items number" (Line 5 in the copy of the command window under). I really can´t read in the code why this happens. Can anyone please help me?</p>

<p>The code of the two classes are as follows:</p>

<pre><code>public class aInvoice
    {
    private String number;
    private String description;
    private int quantity;
    private double price;

    public aInvoice(String pNumber, String pDescription, int pQuantity, double pPrice)
        {
        number = pNumber;
        description = pDescription;
        if (pQuantity &lt; 0)
        {quantity = 0;}
        else
        {quantity = pQuantity;}
        if (pPrice &lt; 0)
        {price = 0;}
        else
        {price = pPrice;}
        }

    public String getNumber()
        {
        return number;
        }
    public String getDescription()
        {
        return description;
        }
    public int getQuantity()
        {
        return quantity;
        }
    public double getPrice()
        {
        return price;
        }

    double totalAmount;
    public double getaInvoiceTotalAmount()
        {
        return quantity * price;
        }
    }
</code></pre>

<p>and:</p>

<pre><code>    import java.util.Scanner;
    public class aInvoiceTest
    {
    public static void main(String[]args)
        {
        String partNumber1 = null;
        String partDescription1 = null;
        int partQuantity1 = 0;
        double partPrice1 = 0.0;
        String partNumber2 = null;
        String partDescription2 = null;
        int partQuantity2 = 0;
        double partPrice2 = 0.0;

        Scanner input = new Scanner (System.in);
        System.out.print( "Enter first items number: ");
        partNumber1 = input.nextLine();
        System.out.print( "Enter description: ");
        partDescription1 = input.nextLine();
        System.out.print( "Enter quantity: ");
        partQuantity1 = input.nextInt();
        System.out.print( "Enter price: $");
        partPrice1 = input.nextDouble();
        System.out.print( "Enter second items number: ");
        partNumber2 = input.nextLine();    
        System.out.print( "Enter description: ");
        partDescription2 = input.nextLine();
        System.out.print( "Enter quantity: ");
        partQuantity2 = input.nextInt();
        System.out.print( "Enter price: $");
        partPrice2 = input.nextDouble();

        aInvoice aInvoice1 = new aInvoice(partNumber1, partDescription1, partQuantity1, partPrice1);
        aInvoice aInvoice2 = new aInvoice(partNumber2, partDescription2, partQuantity2, partPrice2);

        System.out.printf( "\n\nPart 1´s item number: %s\nItem description: %s\nQuantity: %d\nPrice each: $ %.2f\n\n", aInvoice1.getNumber(), aInvoice1.getDescription(), aInvoice1.getQuantity(), aInvoice1.getPrice () );

         System.out.printf( "\n\nPart 2´s item number: %s\nItem description: %s\nQuantity: %d\nPrice each: $ %.2f\n\n", aInvoice2.getNumber(), aInvoice2.getDescription(), aInvoice2.getQuantity(), aInvoice2.getPrice () );

        System.out.printf( "Total amount: $ %.2f\n\n", (aInvoice1.getaInvoiceTotalAmount() + aInvoice2.getaInvoiceTotalAmount()));
        }
    }
</code></pre>

<p>THe reading in the command window is:</p>

<p>Enter first items number: 44
Enter description: pc
Enter quantity: 1
Enter price: $10
Enter second items number: Enter description: phone
Enter quantity: 1
Enter price: $100</p>

<p>Part 1´s item number: 44
Item description: pc
Quantity: 1
Price each: $ 10.00</p>

<p>Part 2´s item number: 
Item description: phone
Quantity: 1
Price each: $ 100.00</p>

<p>Total amount: $ 110.00</p>
