Help needed sorting a text file.

Question

I'm trying to simply open a file, which is a text file of a list of names, then sort that file, the print the sorted file. The problem is that I keep getting this error
Exception in thread "main" java.util.NoSuchElementException: No line found
     at java.util.Scanner.nextLine(Unknown Source)
     at pro.NamesFile.main(NamesFile.java:36)
Which is at this line[b] words= new String(inputFile.nextLine());
It's not reading any lines from the file and I can't figure out why.
Here's the rest of my code:
public class NamesFile {
     public static void main(String[] args) throws FileNotFoundException {
          Scanner inputFile;
        inputFile = new Scanner(new File("C:/Documents and Settings/Cougar/Desktop/New Folder (2)/names.txt"));
        String name;
        inputFile.next();
        String[] words = new String[100];
        while (inputFile.hasNext()) {
             name = inputFile.nextLine();     
             for (int i = 0; i < words.length; i++) {
                  words[i] = new String(inputFile.nextLine());
        Sort2.insertionSort(words);
             for (int index=0; index < words.length; index++)
                System.out.print(words[index].toString()+"\t");
}Here the sort algoritm I'm using, it the insertion sort one.
public static void selectionSort (String[] list)
           int min;
           String temp;
           for (int index = 0; index < list.length-1; index++)
              min = index;
              for (int scan = index+1; scan < list.length; scan++)
                 if (list[scan].compareTo(list[min]) < 0)
                    min = scan;
              // Swap the values
              temp = list[min];
              list[min] = list[index];
              list[index] = temp;
        public static void insertionSort (String[] list)
           for (int index = 1; index < list.length; index++)
                String key = list[index];
              int position = index;
              //  Shift larger values to the right
              while (position > 0 && key.compareTo(list[position-1]) < 0)
                 list[position] = list[position-1];
                 position--;
              list[position] = key;
        }I'm still relativly new at this, so forgive me if there's something obvious that I'm missing.And thanks for any help anybody can give me.

Answer 1

You haven't gotten to running the sort yet, so I didn't even check that the sort routine is correct.
Your problem is:
You say inputFile.hasNext() once, and then you read 1 line from it. Then, in your 'for' loop, you read 100 lines from it. So, you always attempt to read 101 lines, even if the file is shorter than that.
You should call "hasNext" before each call to "readLine". Also, you probably want a "while" loop, instead of a "for" loop, since you don't know how many words you will have. I assume you are expecting 100 or less (based on your array size).
Two more notes:
1. Don't do "new String(inputFile.readLine())". All you need is:
words= inputFile.nextLine();
2. You don't need toString here:
System.out.print(words[index].toString()+"\t");words[index] is already a String, and concatenating the "\t" to words[index] would create a String, anyway, no matter what type words[index] was. And, calling:
System.out.print(words[index]);would also automatically call "toString", even if words[index] were not a String.
You could avoid creation of new Strings by:
System.out.print(words[index]);
System.out.print("\t");Just make sure you add braces around them, if both lines are the body of a 'for' loop. You should also make the second 'for' loop into a 'while' loop, using a counter that you update as you read the lines--so that you don't process the "null" elements of the array. You also need to account for null elements in your sort method.
