java: colorful system.out messages on console

Question

I would like my command line java program to output colored texts into the unix console. I am specifically using gnome-terminal on Ubuntu 10.4. I am able to get colors with something like echo "\\033[01;32m"Hello on the terminal.

How can I trigger this with java code? Thanks

Answer 1

如果您不关心终端兼容性，只需将echo替换为System.out.println(上面。例如，

System.out.println("\033[01;32mHello\n");

Answer 2

The color of text is at the OS layer so I think you can do it using JNI call.

Try this example

Note: make unix equivalent of that,

OR

javacurses is also helpful in your case

OR

enigma-shell is also helpful

Answer 3

This would do the trick:

Process p = Runtime.getRuntime().exec("echo -e \\"\\\\033[01;32m\\"Could Not Add The Task!");

Then redirect the inputStream into the System.out like this:

        BufferedReader stdInput = new BufferedReader(new 
             InputStreamReader(p.getInputStream()));

        while ((s = stdInput.readLine()) != null) {
            System.out.println(s);
        }
