the artist formerly known as Prince

[Martin Smith]

What's with the \f formfeed character. When I try to print it I get the symbol for "the artist formerly known as Prince" (as MTV would call him) -- Honest, try it. It's what people on this forum might call foobar.

Printing "control codes" can get you all sorts of strange looking characters in DOS. Try printing '\u0001' through '\u00031' for some interesting characters.

Marilyn;

Printing "control codes" can get you all sorts of strange looking characters in DOS. Try printing '\u0001' through '\u00031' for some interesting characters.

I tried looking up 'unicode' in the java docs as well as 'control codes' and found nothing - maybe I have the wrong search criteria. So...
Why do I get the following errors

>javac c.java
c.java:10: illegal unicode escape
                uni = "\u000" + i ;
                       ^
c.java:14: illegal unicode escape
                uni = "\u00" + i ;
                       ^
2 errors
>Exit code: 1

With this program

public class c
{
    public static void main( String[] args )
    {
        String uni ;
        for ( int i = 1 ; i <= 31 ; i++ )
        {
            if ( i < 10 )
            {
                uni = "\u000" + i ;
            }
            else
            {
                uni = "\u00" + i ;
            }
            System.out.println( uni ) ;
        }
    }
}

Thanks

Hi doco,
First, you must have exactly four digits following a unicode escape: '\u0001'. Next, your program isn't going to do what you want anyway. You need to iterate thur chars not Strings. Try this instead:

public class c {
    public static void main( String[] args ) {
        char uni = '\u0000';
        for ( int i = 1 ; i <= 31 ; i++ ) {
            uni++ ;
            System.out.println( uni );
        }
    }
}

I figured it out.

public class c
{
    public static void main( String[] args )
    {
        char bChar = '\u0000' ;
        for ( int i = 1 ; i <= 31 ; i++ )
        {
            System.out.println( bChar ) ;
            bChar = (char) ( bChar + 1 ) ;
        }
    }
}

Thanks Michael. I had left my post open while I was looking through other resources and posted what I learned before seeing yours. I like yours better.
