Pramod: >if i write a simple java program that uses a BufferedReader reader object >wrapped from System.in and then try to read a line from user and then echo >it back, cygwin for some reason already has stuff on the stream and so >without waiting for the user to type something in the program fetches that >and prints it out (it is usually) just a newline. why does this happen! The following code works on my system using JDK 1.4.0 and Windows 2000: * * * package test.io; import java.io.*; public class ConsoleInput { public static void main(String[] args) throws IOException { BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); String s = in.readLine(); System.out.println("Echo: " + s); } } * * * There are some issues with reading console input on Win 9x systems that have nothing to do with Cygwin. See, e.g., Java Developer Connection Bug #4071281 at http://developer.java.sun.com/developer/bugParade/bugs/4071281.html. Are you using a Windows 9x flavor?
