public class ConsoleReadingDemo {

public static void main(String[] args) {

  // ====
  BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
  System.out.print("Please enter user name : ");
  String username = null;
  try {
    username = reader.readLine();
  } catch (IOException e) {
    e.printStackTrace();
  }
  System.out.println("You entered : " + username);

  // ===== In Java 5, Java.util,Scanner is used for this purpose.
  Scanner in = new Scanner(System.in);
  System.out.print("Please enter user name : ");
  username = in.nextLine();      
  System.out.println("You entered : " + username);

  // ====== Java 6
  Console console = System.console();
  username = console.readLine("Please enter user name : ");   
  System.out.println("You entered : " + username);

}
}
