Trouble sorting a database

Question

My program is supposed to sort a database based upon whatever key is supplied by the user. The database has 4 parts to each entry, so say the user were to enter the key as 1, the database would sort according to the first part of the entry.
As my program stands now i have key set to 1 without any user input...however I am having trouble with my sort method.
I appreciate anyone willing to take a look
import java.io.*;
import java.util.*;
public class Prog8
     final static int BIG = 16;
     final static int MAX = 4;
     static int count = 0;//# of records
     public static void main(String[] asd)
          DataBase[] dv = new DataBase[BIG];
          readArray(dv);
          System.out.println("before sort");
          printArray(dv);
          System.out.println();
          sort(dv, 2);
          System.out.println("after sort");
          printArray(dv);          
     public static void readArray(DataBase[] dv)
          String line;
          FileStringReader f = new FileStringReader("db.txt");
          DataBase db;//must be instantiated in the loop
          do
               line = f.readLine();
               if(line != null && line.trim().length() != 0)
                    db = new DataBase();
                    readRecord(line, db);
                    dv[count] = db;
                    System.out.println(line+ "|"+count);
                    count++;
          }while( line != null);                    
          System.out.println("final count "+ count);     
     public static void readRecord(String line, DataBase db)
          int j = 0;
          StringTokenizer toke = new StringTokenizer(line);
          while(toke.hasMoreTokens() )
               db.item[j] = toke.nextToken();
               j++;
     public static void printRecord( DataBase db)
          for(int k = 0; k < MAX; k++)
               System.out.print(db.item[k] + " ");
          System.out.println();
     public static void printArray(DataBase[] dv)
          for(int j = 0; j < count; j++)
//               System.out.println("j = "+j);
               printRecord(dv[j] );
     public static void sort(Comparable[] x, int key)
     boolean sorted = false;
     int n = x.length;
     Comparable Database;
     while(!sorted)
          n--;
          sorted = true;
          for(int j = 0; j < n; j++)
               if(x[j].item[key].compareTo(x[j+1].item[key])>0)
                    Database = x[j];
                    x[j] = x[j+ 1];
                    x[j+1] = Database;
                    sorted = false;
class Database
     final int MAX = 4;
String[] item = new String[MAX];
my database is:
