Java Forum / General / November 2005formatted printing of text- color
I don't know how to use println with diferent color of text from default and to print ascii of card signes, like hearts, spike, etc... like: System.out.println("This text is RED, and this is BLUE") Thnx >I don't know how to use println with diferent color of text from > default and to print ascii of card signes, like hearts, spike, etc... > > like: System.out.println("This text is RED, and this is BLUE") > > Thnx Colors are terminal specific (and thus OS specific (and thus probably you won't find direct support for that within Java)). Try looking up ANSI as a starting point. For the card suits and things like that, you can probably find appropriate symbols in Unicode, which Java fully supports. - Oliver "babo" <moron68@hotmail.com> wrote in news:1133303338.159155.299140 @g49g2000cwa.googlegroups.com: > I don't know how to use println with diferent color of text from > default and to print ascii of card signes, like hearts, spike, etc... > > like: System.out.println("This text is RED, and this is BLUE") > > Thnx There currently is no way to change the colour of the output on the console window. There are no ascii heart or spike symbols, so that's out too. You may want to look into using a Swing GUI with a JEditorPane.

This is because the first 32 ASCII characters are non-printing characters such as tab, newline, backspace, escape, ... How these are represented depends greatly on the implementation, the platform, and the platform's settings. Try running this same C program before and after setting the KEYB setting on DOS systems (I don't know if it still works on 32 bit windows systems). You will get very different results. You can see the complete ASCII table at http://www.asciitable.com/ Compare the output from your code above to the table, and you will see that the first 32 characters come out differently, but after that it should be the same. The bottom line is, you can't do what you want in ASCII code. Unicode might help, but you're still not going to get the colours you mentioned in your first post. Why do you want this in the console window anyway? If you want something that looks nice, you really need a GUI.

Consoles don't support colour. You have to create your own logging window that supports colour.

There are libraries that can shield applications from the differences between different console interfaces. A quick Google turns up this library, which I have not used: http://sourceforge.net/projects/javacurses/ Alternatively, if the output is meant only for logging, it might be easier to write some kind of rich text, e.g. HTML. If the output is to be read in real-time, and color is absolutely necessary, Swing might be the best option.

It does not just mean a log display. It is implemented in a platform independent way, which is why no colour. It is surprisingly easy to write your own console log class that has colour, timestamping, persistence etc. SignatureCanadian Mind Products, Roedy Green. http://mindprod.com Java custom programming, consulting and coaching.
