Clear the console and control attributes

For example, on Win9x installation, you need something like this in the CONFIG.SYS :

device=c:\windows\command\ansi.sys

public class AnsiConsole {
  public static void main(String args[]) {
    String ANSI_CLS = "\u001b[2J";
    String ANSI_HOME = "\u001b[H";
    String ANSI_BOLD = "\u001b[1m";
    String ANSI_AT55 = "\u001b[10;10H";
    String ANSI_REVERSEON = "\u001b[7m";
    String ANSI_NORMAL = "\u001b[0m";
    String ANSI_WHITEONBLUE = "\u001b[37;44m";

    System.out.println(ANSI_CLS);
    System.out.println
       (ANSI_AT55 + ANSI_REVERSEON + "Hello world" + ANSI_NORMAL);
    System.out.println
       (ANSI_HOME + ANSI_WHITEONBLUE + "Hello world" + ANSI_NORMAL);
    System.out.print
       (ANSI_BOLD + "Press a key..." + ANSI_NORMAL);
    try {System.in.read();}catch(Exception e){}
    System.out.println(ANSI_CLS);
    }
  }

NT's CMD.EXE does not support ANSI escape sequences. The Good news is that you can use COMMAND.COM instead. To use ANSI.SYS, add the following lines in the CONFIG.NT file:

 dosonly
 device=c:\winnt\system32\ansi.sys

So the only solution left for NT (unless you write some JNI functions, see this HowTo) is to use brute force.
