Why won't the array not sort alphabetically?

Question

public static void main(String[] args)
{
    String file = "";
    Scanner a = null;
    try
    {
        a = new Scanner(new File("names.txt"));
    }
    catch (FileNotFoundException e)
    {
        System.out.println("There was an error with your file");
        e.printStackTrace();
    }
    while(a.hasNextLine())
    {
        file = file +a.nextLine();
        file +="\n";
    }
    System.out.println(file);
    String name [] = {file};
    int i;
    for(i=0;i<name.length;i++)
    {
        for(int j=i+1;j<name.length;j++)
        {

            if(name[i].substring(0,1).compareTo(name[j].substring(0,1))<0)
            {
                String temp = name[i];
                name[i] = name[j];
                name[j] = temp;
            }
        }
    }
    for(i = 0;i < name.length;i++)
        System.out.println(name[i]);

note: the file's content is as follows:

John
Rachel
Peter
Illyana
Erik
Jimmy
Dan
Ken
Guile
Barbara

The output is:

John
Rachel
Peter
Illyana
Erik
Jimmy
Dan
Ken
Guile
Barbara

John
Rachel
Peter
Illyana
Erik
Jimmy
Dan
Ken
Guile
Barbara

**I'm using OS X, can that be the source of the problem?

Answer 1

String name [] = {file};
You just initialize the array with one item in it , you just connected names with \\n ,seems like an array with multi items . You can initialize it like this :
String name[] = file.split("\\n");

Answer 2

public static void main(String[] args) {
    String file = "";
    Scanner a = null;
    try {
        a = new Scanner(new File("E:\\names.txt"));
    } catch (FileNotFoundException e) {
        System.out.println("There was an error with your file");
        e.printStackTrace();
    }
    List<String> name;
    name = new ArrayList<String>();
    while (a.hasNextLine()) {
        file = a.nextLine();
        name.add(file);
        file += "\n";
    }
    System.out.println(file);
    int i;
    for (i = 0; i < name.size(); i++) {
        for (int j = i + 1; j < name.size(); j++) {

            if (name.get(i).substring(0, 1)
                    .compareTo(name.get(j).substring(0, 1)) < 0) {
                String temp = name.get(i);
                name.set(i, name.get(j));
                name.set(j, temp);
            }
        }
    }
    for (i = 0; i < name.size(); i++)
        System.out.println(name.get(i));
}

Use ArrayList instead of String so that you don't have to specify the size to initialize.

The above code is working. You can make modifications if required.
