Java my program's array is not showing any values

I'm writing a program to search for a string and tell me were it was found.

import java.io.*;


public class BinarySearchTest
{
   public static void main(String [] args) throws IOException
   {
      int result;
      String searchValue;
      String input;

      // An array of numbers to search.
      String[] numbers = {"Jake", "Jerry", "Bill", "Lousie", "Goku", "Ivan", "John", "sarah", "kim"};

      // Create the consol开发者_开发技巧e input objects.
      InputStreamReader reader =
                 new InputStreamReader(System.in);
      BufferedReader keyboard =
                 new BufferedReader(reader);

      // First we must sort the array in ascending order.
      IntQuickSorter.quickSort(numbers);

      do
      {
         // Get a value to search for.
         System.out.print("Enter a value to search for: ");
         input = keyboard.readLine();
         searchValue = input;

         // Search for the value
         result = IntBinarySearcher.i;

        // Display the results.
        if (result == -1)
           System.out.println(searchValue + " was not found.");
        else
        {
           System.out.println(searchValue + " was found at " +
                              "element " + result);
        }

        // Does the user want to search again?
        System.out.print("Do you want to search again? (Y or N): ");
        input = keyboard.readLine();
      } while (input.charAt(0) == 'y' || input.charAt(0) == 'Y');
   }
}

There's something missing:

searchValue = input;

//IntBinarySearcher.search(numbers, searchValue); here?

// Search for the value
result = IntBinarySearcher.i;

Edit:

This won't work either since IntBinarySearcher.i is never "correctly" set (see Edit2) :).

Better:

result = IntBinarySearcher.search(numbers, searchValue);

Edit 2:

Oh, and this would throw a NumberFormatException for value="Bill": setI(Integer.parseInt(value));

You don't appear to be performing the search. You need the line:

IntBinarySearcher.search(numbers, searchValue);

before the line:

result = IntBinarySearcher.i;

---

You don't call IntQuickSorter.search() anywhere. Call it after

searchValue = input;

---

I don't see in your code where you're making a call to IntBinarySearcher.search. Without that i won't be set to anything, right?
