Accessing a public array from extra class.

Question

I am trying to access a public array that I declared in my main class from a separate class. I am a bit confused about why this is not working.
The method search in the extra class is called in the extra class in part one of the nextKeystream method. How can I get it to use the int array "key". That I declared in the MainSolitaireDriver?
Thanks
My main class:
import java.util.*;
import java.io.*;
import java.util.Scanner;
public class MainSolitaireDriver
   int pcount = 0;
   public int[] key = new int[26];    
   public MainSolitaireDriver()
       getValues();
        public void getValues()
            try
                Scanner inFile = new  Scanner(new File("input.txt"));
                for (int counter = 0; counter < key.length; counter++ )
                    key[counter]= inFile.nextInt();
                    System.out.print(key[counter]+" ");
            catch(FileNotFoundException e )
            e.printStackTrace();
            System.err.print("Failure- File Not Found");
     public static void main (String[] args)
            /*String whereInTheWorldMyFileShouldBe = new File("input.txt").getAbsolutePath();
System.out.println(whereInTheWorldMyFileShouldBe); */
}My extra class:
public class Solitaire
     private Deck deck;
     *  Initialize the deck from the current key deck ordering.
     public Solitaire (int[] shuffle)
          deck = new Deck(shuffle);
        public void getArray(int[] Array)
        public int search(int [] span, int target)
            for (int indexcount = 0; indexcount < span.length; indexcount++)
                if (span[indexcount]==target)
                    return indexcount;
        public void getArray(int[] a)
     *  Returns the next keystream generated by the Solitaire  Algorithm
     public int nextKeystream()
          // Step one: Move Joker A one card down.
                int jokerAindex = search(MainSolitaireDriver(key), 27);
                System.out.print(jokerAindex);
          // Step two: Move Joker B two cards down.
          // Step three: Perform a triple cut.
          // Step four: Perform a count cut.
          // Step five: Find the output card.
          return 0;
     *  Returns the ciphertext corresponding to the specified
   *  plaintext, according to the current key deck ordering.
     public String encrypt(String plaintext)
          return "";
     *  Returns the plaintext corresponding to the specified
   *  ciphertext, according to the current key deck ordering.
     public String decrypt(String ciphertext)
          return "";
}
