    java input help

    I'll get straight to the point.

    I have the following procedure:

    public static String readLine (String prompt) {
       	System.out.print( prompt );
       	try {
       	InputStreamReader isr = new InputStreamReader (;
       	BufferedReader br = new BufferedReader(isr);
       	String s = br.readLine ();
       	System.out.println ("");
       	return s;
       	catch (IOException e)
       	{ System.out.println("IO Exception ");
       	System.exit (-1);
    	return "EXCEPTION";
    } // end readLine
    and this procedure:

    public static void login() 
    	String user = readLine("user:") ;
    	String pass = readLine("pass:") ;
    System.out.println("user is " + user + " pass is " + pass) ;
    } // end login

    both procedures are in the same .java file.
    My question is, when im running this in a dos prompt window, If i want input from a file, I type
    java [classname] < [input file]

    but when I have a simple text file with the following data:


    .. and I direct this file into my program with the above line of code, I get the following output:

    "user is scott pass is null "

    can someone please tell me why the second line in the text file is not being read in?

    thanks in advance.

    No offense or anything, but what is the title of this site?

    You might want to try where there are a lot more java developers.

    Even though this isn't "", I'll suggest that you try putting a blank newline or some dummy text after the password.
