How to set a string s color

Question

Does anyone know how I would set the color of a string that will be printed using System out  This is the code I currently have   System out println  TEXT THAT NEEDS TO BE A DIFFERENT COLOR

Console

See the Wikipedia page on ANSI escapes for the full collection of sequences, including the colors.

But for one simple example (Printing in red) in Java (as you tagged this as Java) do:

System.out.println("\u001B31;1mhello world!");

The 3 indicates change color, the first 1 indicates red (green would be 2) and the second 1 indicates do it in "bright" mode.

GUI

However, if you want to print to a GUI the easiest way is to use html:

JEditorPane pane = new new JEditorPane();
pane.setText("<html><font color=\"red\">hello world!</font></html>");

For more details on this sort of thing, see the Swing Tutorial. It is also possible by using styles in a JTextPane. Here is a helpful example of code to do this easily with a JTextPane (added from helpful comment).

JTextArea is a single coloured Text component, as described here. It can only display in one color. You can set the color for the whole JTextArea like this:

JTextArea area = new JTextArea("hello world");
area.setForeground(Color.red)

Strings don t encapsulate color information    Are you thinking of setting the color in a console or in the GUI

I created an API called JCDP  former JPrinter  which stands for Java Colored Debug Printer  For Linux it uses the ANSI escape codes that WhiteFang mentioned  but abstracts them using words instead of codes which is much more intuitive  For Windows it actually includes the JAnsi library but creates an abstraction layer over it  maintaining the intuitive and simple interface created for Linux   This library is licensed under the MIT License so feel free to use it   Have a look at JCDP s github repository

If you re printing to stdout  it depends on the terminal you re printing to  You can use ansi escape codes on xterms and other similar terminal emulators  Here s a bash code snippet that will print all 255 colors supported by xterm  putty and Konsole    for   i 0 i lt 256 i      do echo -en   e 38 5   i m  i     done   You can use these escape codes in any programming language  It s better to rely on a library that will decide which codes to use depending on architecture and the content of the TERM environment variable
