    <p>I have the following program in which a user enter his social security number and is assigned a location that correspond to it.</p> <p>One thing I do not get is how can I add a loop to search through through my array until it find the correct area number and the area it correspond to for example 3 correspond to new hampshire. I tried a loop in my program but I am not sure how to make it work. </p> <pre><code>import jpb.*; public class SSNInfo { public static void main(String[] args) { SimpleIO.prompt("Enter a Social Security number: "); String ssn = SimpleIO.readLine().trim(); while (true) { if (ssn.length() != 11) { System.out.println("Error: Number must have 11 " + "characters"); } else if (ssn.charAt(3) != '-' || ssn.charAt(6) != '-') { System.out.println( "Error: Number must have the form ddd-dd-dddd"); } else break; SimpleIO.prompt("\nPlease re-enter number: "); ssn = SimpleIO.readLine().trim(); } // Get the area number (the first 3 digits of the SSN) int area = Integer.parseInt(ssn.substring(0, 3)); int[] areaNumbers = { 3, 7, 9, 34, 39, 49, 134, 158, 211, 220, 222, 231, 236, 246, 251, 260, 267, 302, 317, 361, 386, 399, 407, 415, 424, 428, 432, 439, 448, 467, 477, 485, 500, 502, 504, 508, 515, 517, 519, 520, 524, 525, 527, 529, 530, 539, 544, 573, 574, 576, 579, 580, 584, 585, 586, 588, 595, 599, 601, 626, 645, 647, 649, 653, 658, 665, 675, 679, 680}; String[] locations = {"New Hampshire", "Maine", "Vermont", "Massachusetts", "Rhode Island", "Connecticut", "New York", "New Jersey", "Pennsylvania", "Maryland", "Delaware", "Virginia", "West Virginia", "North Carolina", "South Carolina", "Georgia", "Florida", "Ohio", "Indiana", "Illinois", "Michigan", "Wisconsin", "Kentucky", "Tennessee", "Alabama", "Mississippi", "Arkansas", "Louisiana", "Oklahoma", "Texas", "Minnesota", "Iowa", "Missouri", "North Dakota", "South Dakota", "Nebraska", "Kansas", "Montana", "Idaho", "Wyoming", "Colorado", "New Mexico", "Arizona", "Utah", "Nevada", "Washington", "Oregon", "California", "Alaska", "Hawaii", "District of Columbia", "Virgin Islands", "Puerto Rico", "New Mexico", "Pacific Islands", "Mississippi", "Florida", "Puerto Rico", "Arizona", "California", "Texas", "Utah", "New Mexico", "Colorado", "South Carolina", "Louisiana", "Georgia", "Arkansas", "Nevada"}; } int i; for (i = 0; i &lt; areaNumbers.length; i++) if areanumbers[i] == int area; break; } </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.
