[Bluej-discuss] "Backspace" escape character

[TJ Evert]

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?
