Read user input from Windows commandline print only from second letter - Java

Question

When I run below lines in Windows command line it does not take the first letter. If I enter 22 it prints only '2'

private static String  readInput() {
    try {
         BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
         input = br.readLine();
         System.out.println("input "+input);

   } catch (Exception ioe) {
      System.out.println("Error trying to read your input!");
      ioe.printStackTrace();
   }
}

are you sure that Eclipse version and DOS version are the same? — Scary Wombat, Mar 12 '14 at 08:04
Sorry I'm lost what is it? I build the jar file and use the command >java -jar MyProg.jar then it call my main class and that class tries to get the user input — user2771655, Mar 12 '14 at 08:06
@Homayoun Afshari This is the code. From the main method its calling this method to take the user input. — user2771655, Mar 12 '14 at 08:13

Try this.

   while((input = br.readLine()) != null){
         System.out.println("input "+input);
    }

Program doesn't continue. Its continues within the while. EX: Enter the service number : 1 input input input – user2771655 Mar 12 '14 at 08:10

try like this!

private static String  readInput() {
try {
     DataInputStream in=new DataInputStream(System.in);
     input = in.readLine();
     System.out.println("input "+input);
     return input;
   } catch (Exception ioe) {
      System.out.println("Error trying to read your input!");
      ioe.printStackTrace();
   }
}

Ok I found the problem. Its not relate to scanner or BufferedReader. All works fine. One of my another back end thread is reading System.in.read();. That's why I always missed first input. Sorry for confusing all of you.
