    <p>Consider only starting to read the input again. If it is what you need, the following would be suitable:</p> <p>Put the method getData() in the Distance class. The class Distance must have a nonparametric constructor.</p> <p>Distance.java</p> <pre><code>private double latitude; private double longitude; private double elevation; private double latitude2; private double longitude2; private double elevation2; public Distance() {} public boolean getData(){ Console.WriteLine("Please enter the two points that you wish to know the distance between:"); string point = Console.ReadLine(); string[] pointInput = point.Split(' '); int pointNumber = Convert.ToInt16(pointInput[0]); int pointNumber2 = Convert.ToInt16(pointInput[1]); try{ latitude = (Convert.ToDouble(items[pointNumber * 3])); // longtitude = (Convert.ToDouble(items[(pointNumber * 3) + 1])); // elevation = (Convert.ToDouble(items[(pointNumber * 3) + 2])); // latitude2 = (Convert.ToDouble(items[pointNumber2 * 3])); // longtitude2 = (Convert.ToDouble(items[(pointNumber2 * 3) + 1])); // elevation2 = (Convert.ToDouble(items[(pointNumber2 * 3) + 2])); // I assume the exception goes from these 6 lines return true; } catch (IndexOutOfRangeException) { return false; } } </code></pre> <p>Main.java:</p> <pre><code>Distance curDistance = new Distance(); while(!curDistance.getData()) Console.WriteLine("You have selected a point number outside the range of the data entered, please select two new pointnumbers"); Console.WriteLine("The distance in km's to two decimal places is:"); Console.WriteLine(String.Format("{0:0.00}", curDistance.toDistance()) + "km"); </code></pre> <p>The while loop makes the program ask for the input as long as it's incorrect.</p>

Guidance
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.
