title: read in 2 files, convert to arrays, then print what has been called
body: <p>So the data in the files are girls &amp; boys names. The order is the popularity and the corresponding number is the number of times the name was registered in a certain year. eg:  </p>
  
  <p>Frank 678<br>
  William 2<br>
  etc  </p>
  
  <p>There are 1000 names in each file. I need to load each file into <code>string[]</code> &amp; <code>int[]</code>, then when a name is written into the keyboard, the program must go thou the arrays, find the name, print out the index of the string array (less one obviously) &amp; the number that is in the <code>int[]</code>. my current code is just returning 1000, 1000. so I'm not sure where I'm going wrong 
  Hope this makes sense, its for a uni question. Here is my code so far, sorry if it seems primitive, I'm still learning :-)</p>

  public class H252{
  
      static final int ENTRIES = 1000; // Number of entries in the file

          int number = 0;
  
          for (int i = 0; i &lt; entries.length - 1; i++)
              if (entries[i] == target)
                  number = i + 1;
              else
                  number = ENTRIES;
  
          return number;
      }
  
      public static void LoadFile(String[] entries, int[] count, String filename) {

                  entries[a++] = file.next();
  
              if (file.hasNextInt())
                  count[b++] = file.nextInt();
          }
  
      }

              Scanner kb = new Scanner(System.in);
              String getName = kb.next();
  
              String[] boyNames = new String[ENTRIES];
              String[] girlNames = new String[ENTRIES];
              int[] countB = new int[ENTRIES];
              int[] countG = new int[ENTRIES];
  
              LoadFile(girlNames, countG, "girlnames.txt");
              System.out.print(isInArray(girlNames, getName)
                      + countG[isInArray(girlNames, getName) - 1]);
              LoadFile(boyNames, countB, "boynames.txt");
              System.out.print(isInArray(boyNames, getName)
                      + countB[isInArray(boyNames, getName) - 1]);
