Need help with transfering names from a txt file to array

[supahsain08]

Hello, my program is suppose to read data from a txt file
txt file has like 20 names (each name on a different line)

code:

For example Sam dam dog lamb

I am almost done, but i am experiencing problems reading names from a txt file

here's my code so far

code:

import java.io.*; public class sort {     public static void main (String[] args) throws Exception     {         FileInputStream File1;         DataInputStream In;         String fileInput = "";         File1 = new FileInputStream ("names.txt");         In = new DataInputStream (File1);         while (In.available () > 0)         {             fileInput = In.readLine ();             System.out.println (fileInput);         }         System.out.println ("\n\n\n");          // How do i import names from the txt file here         String[] names = {"joe", "Slim", "Ed", "george"};         sort1 (names);         for (int k = 0 ; k < 4 ; k++)             System.out.println (names [k]);     }     public static void sort1 (String x[])     {         int i, j;         String temp;         for (i = 0 ; i < x.length - 1 ; i++)         {             for (j = i + 1 ; j < x.length ; j++)             {                 if (x [i].compareToIgnoreCase (x [j]) > 0)                 { // ascending sort                     temp = x [i];                     x [i] = x [j];                     x [j] = temp;                 }             }         }     } }

Well to start I would suggest switching to a Scanner just to reduce the linecount:

code:

Scanner s = new Scanner(new File("File.txt"));

I believe you are asking how to transfer the names into an array. IMO the easiest way would be to use an ArrayList:

code:

ArrayList<String> a = new ArrayList<String>(); while (s.hasNext())     a.add(s.nextLine());

I really don't see any reason not to use the built in classes to do this. Since it seems that you are learning sorting algorithms, you probbably want a real array so you can use ArrayList.toArray() and have the entire thing read into an array in 5 lines.
