java System.err.println output is red

Question

I am programming following thing:

public static void main(String[] args){
System.err.println("Watch on youtube: Mickey en de stomende drol");
}

My output is:

Watch on youtube: Mickey en de stomende drol

Which seems ok but the font color of the output is red. It should be black. How do I make the output black?

This is not problem of your Java code, this is your console setting. — vojta, Mar 19 '15 at 15:26
why did you print out `err` instead of `out`? `err` is standard printed red because it's used for errors like `err` should suggest — Zorian, Mar 19 '15 at 15:26
`System.err.println` prints red because it is an error while `System.out.println` prints black... — brso05, Mar 19 '15 at 15:29
I didn't know that System.out.println existed. I thought that err existed for Ending Readable Reddit message, not for error. — Jonas Audenaert, Mar 19 '15 at 15:30
so the easiest is to change `err` to `out` [here](http://tutorials.jenkov.com/java-io/system-in-out-error.html) you find some informations about that and I suggest to read a bit more on this topic because if you change the color in your IDE and you have a lot ouf output in your console, it could be hard to find a printed out error — Zorian, Mar 19 '15 at 15:37

This is due to your console, not Java code. The console is displaying stderr differently from stdout, to make it stand out a bit more.

In IntelliJ IDEA (which you mentioned in your comments), the setting is:

Preferences -> Editor -> Colors & Fonts -> Console error output

Change that to whatever color you want.

you must use

System.out.println("Watch on youtube: Mickey en de stomende drol");

err is always red in default if you want change it you must change your ide setting

that is because you are printing an error you should use System.out.println()

The color of standard error is environment specific and nothing to do with your code. That said for various environment there are various ways :

For IntelliJ go to Settings -> Editor -> Colors & Fonts -> ConsoleColors

Change the colors as per your wish.
