[Bluej-discuss] "Backspace" escape character

[RDP]

My experience has been that the font selected will print a square character for unknown values.

The encoding for the font, Western (ISO) also affects the output.  So the character set used (for example Unicode).  I've tried selecting a font-face in the code.

  Dear all,

  My class and I are writing methods that act on Strings and (in the past) I've used the "\b" escape character for an "untype()" method (which uses a delay() method) as follows:

  public static void untype(String str)
  {
      int len = str.length();
      System.out.print(str);

      for(int i = 0; i < len; i++)
      {
          delay(1000);
          System.out.print("\b \b");
      }
  }

  public static void delay(long milliSeconds)
  {
      long now = System.currentTimeMillis();
      long later = now + milliSeconds;
          
      while(later > now)
      {
          now = System.currentTimeMillis();
      }
  }

  The problem is that BlueJ types out a "box" character. Any thoughts?
