    <p>I am trying to make a method that searches a String array for an inputted state and returns the index. If the user enters a query that is not in the array, I would like it to ask for a new state to search. At the moment I am stuck in the loop. I know I am entering a valid state, but it keeps asking for a valid state and will out let me out of the loop.</p> <p>Thank you.</p> <pre><code>public static void main(String[] args) throws FileNotFoundException { String[] stateNames = importFile("stateNames.txt"); String[] nicknames = importFile("nicknames.txt"); String[] populations = importFile("population.txt"); String[] flowers = importFile("flowers.txt"); String[] Capital = importFile("capitals.txt"); int index = askState(stateNames); System.out.println("The index of your state is"+ index); } static final int NUM_STATES = 50; public static String[] importFile(String fileName) throws FileNotFoundException { String[] array = new String[NUM_STATES]; File inputFile = new File(fileName); Scanner scanner = new Scanner(inputFile); for (int i = 0; i &lt; NUM_STATES; i++) { array[i] = scanner.nextLine(); } return array; } public static int askState(String[] stateNames) { Scanner keyboard = new Scanner(System.in); String state; int statePosition = -1; System.out.println("Please enter a state that you would like to search:"); state = keyboard.nextLine(); { for (int i = 0; i &lt; NUM_STATES; i++) { if (state.equals(stateNames[i])) statePosition = i; else { System.out.println("Please enter a valid state:"); state = keyboard.next(); }} return statePosition; } } </code></pre> <p>}</p>

    1. COYou tell the user to enter a valid state as soon as you find an item in the array that is not equal to the entered state. You must do that only when you're sure that ALL the items in the array are different from the entered state. And you'll only know that once you've examined every element of the array. My advice: write a method `int indexOfItemInArray(String[] array, String item)`

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.
